FC Front Brake Upgrade

[Oly AE86]

AE86 Brake Upgrade Using RX7 FC3S Calipers and Mini Cooper S Rotors.

Items required:

*Brake Calipers, 1990 Approx RX7 Series 4/5 Turbo $135 Calipers, $160 to rebuild
*Brake Pads, Brakes Plus Premium Plus $75 Trade
*2001 Mini Cooper S Rotors, 276mm dia, 22mm thick, 64mm centre hole (same as AE86) DBA P.N. 542 RDA P.N. 7352S (slotted) $285 Pair
*Custom made bracket to fit Calipers to AE86 Hubs
*4x M12 x 30mm Cap Head Bolts
*8x M12 x 35mm Cap Head Bolts

First, brake adapter bracket.

Using CAD drawings from Twinky on Toymods (Link (http://www.toymods.net/forums/showthread.php?t=8314)), brackets are milled from solid steel on CNC. These were made cheaply by some guys at work, but with the drawings I think any fabrication shop could do it. Bracket 1 (http://www.mediafire.com/imageview.php?quickkey=mjzzq5hyqvx&thumb=4) Bracket 2 (http://www.mediafire.com/imageview.php?quickkey=vjommxqcb2m&thumb=4) I have dimensioned CAD drawings if anyone is interested.

Second, modify Mini rotors

The rotors have a chamfer on the inside where they locate on the hub, a new chamfer needs to be made on the opposite side to fit over the AE86 hub, this can be done on a lathe in a few minutes.

http://www.ae86drivingclub.com.au/dcimages/4/8/4/3/119826.jpg

Third, modify Sprinter hub

Because the disk is so much larger, I replaced the standard M10 bolts that mount the disc on the hub with new High Tensile M12 items, so the holes on the hub were drilled out to 10.2mm, and re-tapped at M12.

Then, using the AE86 hub, re-drill holes in rotors to mount onto reverse of hub, PCD is about 87mm but having the old rotors and hubs you have a template.

Then, assemble the whole setup. Original AE86 brake lines can be used, or replacement braided units (ex. From AJPS $180) would sweeten up the system. Original master cylinder can also be used, with a T-18 rear end my pedal feels squishy at first, then firms up. Nissan R32 non-ABS units apparently bolt straight on, with 15/16 bore create better pedal feel, will try that next.

Clearance is good with 15'' SSR wheels, about 1cm to the outside of the rim. There is a clearance issue with the spokes so I am currently running a 7mm spacer, and looking into either different offset 15'' or another SSR wheel.

There is no problem with clearing the LCA, other setups use a rotor with high offset that requires NCRCA's, I do have these fitted but are not necessary.

awesome article. will be a great lot of help in the near future

did you just take the dimensions down to a machining shop? or have you made up a CAD drawing yourself?

[Oly AE86]

I got some CAD drawings from Twinky on Toymods, changed them around so they are easier to understand and took them to work.

The guys drew them on the CNC and the machine did the rest. I think if you took the printed drawings to a machine shop they could make them without too much hassle.

[Tom86]

What the stopping power like now? is it worth the effort?

[Oly AE86]

Its pretty good once the rotors get a bit of warmth into them. When they are cold or if I start driving when its raining they take a bit to warm up and work well.

I am putting in the R32 master this weekend, should take away the spongy feel and improve the bite.

[Bustin_86]

thats awesome man... many thanks for such a comprehensive article!

[RobertoX]

good work man! thx for the plug

[Hen is a total nutcase]

Wow, those adaptors are awesome. Whoever designed them must have been a genius.

Hen

[Oly AE86]

Yea, thanks Hen! Without your originals these would not have been created. http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

[70XIN]

Thanks for your reply! http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

Oh, and another quick question .. who would be a good person to try for the lathe work on the brakes?

And in regards to the adaptors, would your work be able to make up a couple more? http://www.ae86drivingclub.com.au/forums/emoticons/wub.gif I have the brake calipers and the money waiting, i was just a bit scared to do the upgrade until now http://www.ae86drivingclub.com.au/forums/emoticons/2thumbs.gif

[Oly AE86]

In regards to the rotor mods, if you found a place that could machine the brackets, they would have a lathe and could do the chamfer on the rotor.

The guys at work did the brackets as a one off for me, they can't easily make any more.

Maybe try yellow pages to find an engineering or machining shop that can do this kinda thing for you. http://www.ae86drivingclub.com.au/forums/emoticons/huh.gif

[balistic]

If anyone decides to get brackets made up I would be very insterested in a set as well. I will looking at maybe getting some made up but it wont be for a little while yet as I have other priorities on the car at the moment.

[butterz]

Hay dude sweet tech info could u pm me the dimensioned CAD drawings????
let us know how the R32 master goes 2 http://www.ae86drivingclub.com.au/forums/emoticons/2thumbs.gif do u have a part number for it ect??

[Gilly]

S13, R32, 33 and 34 2 port master work (can't remeber whether thats ABS or not) they bolt up to the 86 booster, just need solid lines made to suit

[Hen is a total nutcase]

With R32 (non-ABS) master, all lines fit, the front driver's is tight though, and could do with a new, slightly longer one.

I suspect this would also be true for the other masters listed above, but cant confirm.

Hen

[mc68]

r32 NA or gtst?

[Oly AE86]

I have ordered R32 GTS-T Non-ABS, hopefully getting here today or tomorrow.

From what I have heard like Hen said should be a little tight but will fit with standard lines.

[Hen is a total nutcase]

I got one from a GTS-t, never checked if NA is the same.

20V, where are you ordering one from? I heard Nissan no longer stocked them.

Hen

[PuGZoR]

Could you email me the CAD drawings mate? Email addy is pugzor(at)pugzor(dot)net. I can repost them on my website if anyone wants them, or if it makes it easier for you rather than sending them to anyone who wants them?

[Oly AE86]

Hey

Zip file with CAD Drawings is located here: zip File (http://putstuff.putfile.com/3741/8474889)

You will need AutoCad 2000 or newer to view the files.

I got the R32 GTS-T Non ABS Master cylinder from Autotech Imports in Adelaide.

They had a listing for an R33 Item on eBay, but after an email they sourced an R32 model. Autotech Website (http://www.autotechimports.com.au/)

Its obviously a used item, but I will try and re-seal it. It cost me $80 shipped.

I'm checking out the possibility of getting some brackets to fit FC calipers to AE86 using Honda Civic EG6 vented rotors. They are from a maunfacturer in Japan. If anyone else is interested I'll see if we can get a better price for a larger order.

Not sure if anythings going to go ahead yet but I'll post back when I know more.

Leo, is that the EG6 rotor in the middle with the FC caliper? You have this setup now?

[44GTE]

I Already have the brackets from Japan and was told that i would only need to mill off about 2mm on the caliper mount flange to then be able to use the Cooper S 276mm rotors.

I can post up picks of these brackets if anybody is interested.

Yes please~! I have calipers now and just need to source brackets.

[rthy]

yes it is

wats the difference from the eg6 and coopers rotor?

[balistic]

I just checked the DBA catalog:

Mini Cooper S (Supercharged)rotor:
A = 276
B = 44
C = 22
D = 19
E = 64
F = 4

Honda Civic EG rotor:
A = 262
B = 45
C = 21
D = 19
E = 64
F = 4

They appear to be VERY close but the Mini Cooper S rotor is 14mm larger in diameter? I would think this would require the caliper to be located further away of the hub?

[mc68]

what are the chances you reckon of fitting 14's over these? No chance? http://www.ae86drivingclub.com.au/forums/emoticons/tongue.gif

[rthy]

the eg6 disks fit under 14"

[44GTE]

I have a set of 14" superlights in the shed and they fitted over this setup with the brackets and Mini Cooper S 276mm rotors.

hmm fuck yeah, this will be tops on a rally car http://www.ae86drivingclub.com.au/forums/emoticons/biggrin.gif

and also, are the rotors from an Eg6 special or anything,like a type R or something? or just a normal aus delivered cvic?

does anyone have a dba number? http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

taa.

[44GTE]

Any intersted parites if i can get these made in steel ??/

[hilux08]

depending on price might be

[balistic]

Yeah price will be the deciding factor - I'm currently looking at getting a price for the alloy ones from Japan through an importer mate, if they work out cheaper than that then yeah I'm keen! Any reason your not getting them done in alloy?


and also, are the rotors from an Eg6 special or anything,like a type R or something? or just a normal aus delivered cvic?

does anyone have a dba number?[/b]

AFAIK they are a standard rotor for most late model Civics, the DBA part number I have from their catalog is #474, I'm assuming these are the correct rotors, as mentioned they are very close specs to the Mini Cooper S rotors which are being used here for FC caliper conversion. I would prefer the Mini Cooper S rotors as I will be using 15" wheels - so no clearance issues http://www.ae86drivingclub.com.au/forums/emoticons/biggrin.gif

[44GTE]

I am pretty keen to just put them on the car in the alloy setup but am under the impression that most enginers don't like alloy brackets and want steel ones thats all.

I have everthing here now along with the R32 master cycl to just bolt up but will need the bracket off the car to have a set made up as the masters first though.

Anybody know of a good maching shop for replicating these in Steel ??

Pm ME if you do with there contacts, preferably on the north side of Brisvegas .

how much where the r32 master cylinders? and where can u get them from?

[44GTE]

Highlife
These weren't cheap , i will add as i had then brought in from Japan through a import broker.
But would be willing to sell if you were interested once i have some steel ones though. PM Me what you are offering for them.

ryth

I brought mine from Jap Performance Moorebank NSW 0296016715 , it was $105 delivered. I think that they had this one on the shelf already removed froma booster though. Not sure if they have any more at the moment, just drop them a line to see.

Cheers

[Hen is a total nutcase]

Guys a few years ago when I had a set of these made, a machinist friend quoted a normal price of about $500-600 a pair for these machined from a single piece of steel.

Using Mini discs reduces the amount needed to be milled out, of the adaptor but it could well still be fairly steep in steel.

The guy who did mine was Gerard Hook from Hand-On Engineering in Melbourne, (03) 9431 0457. He will probably remember the job. Also he's all set up so if you email him a CAD file he'll produce it from that no problem.

Yeah I know they arent that cheap, I have a price for the kit from Japan(EG Civic rotors and brackets). But have a mate chasing down what he can get just the brackets for as I can source rotors locally. Also checking if its cheaper to get 2 or 3 sets and on sell the others to save some cash? When I have a price for them from Japan I'll be able to make you an offer. http://www.ae86drivingclub.com.au/forums/emoticons/wink.gif

There is also an R32 Master Cylinder available in Capalaba, QLD if someone more local is after one.

Will be working on car over the Christmas break, will get it fitted up then. Will upload some photos after its done too.

BlueAE86, i would be very intersted in a kit for the RX7 calipers

[mc68]

heh, got my kit from jland today...im happy with that http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif calipers are in top condish too!..i dont even have to get them rebuilt :\

pretty good bang considering it was only 670 odd too my door.

[balistic]

..just continuing on from this - I can get brackets made up pretty cheaply(<$300 pr) if its possible to have them cut out of 2 x 10mm plates and welded together. (have a mate who works for a laser cutting mob).

I'm going to pull my struts off this weekend and see what I can come up with - in the meantime does anyone have any ideas if this is possible? The CAD drawings posted above have the material thicknesses at 9mm and 11mm if it were made up from two plates welded together.

Could these be made from mild steel or will there be issues?

[Oly AE86]

Mild Steel would be fine, that is what my plates are milled from.

Also, the 2 plates welded idea is also a good one. The original plates that "Twinky" from Toymods made were 2 separate items that were doweled then welded together.

[balistic]

I've seen master cylinders with 2 outlets and 3 outlets, I'm assuming you only need the 2 outlet master? Whats the 3rd outlet for?

[Big T]

3rd outlet is probably for left/right front brakes. Means you can get rid of the factory splitter on the firewall.

[Joel-AE86]

I once created a CAD design of one of these adapters. I reckon someone who I did if for may be/or sent it to Twinky!

I should've patented it!

^^^ Joel, I drew them from scratch too, and sent them to Twinky.

Patenting FTW though.

My GF does Patents and Copyrights, I can hook you up. http://www.ae86drivingclub.com.au/forums/emoticons/tup.gif http://www.ae86drivingclub.com.au/forums/emoticons/biggrin.gif

As long as I can keep my brackets. http://www.ae86drivingclub.com.au/forums/emoticons/cool.gif

Still havn't got the R32 master installed, there is more work required than just bolt-on and has not been off road for long enough.

Spend a day at Mt Cotton doing an advanced car control driving course, and the brakes were friggin awesome.

I was stopping with ease where some people with ABS were struggling, they have pretty good bite.

Will probably install it one day, and see how it goes.

Good work Oly,

I am still in the process of getting all the bits together but I was JUST about to order the rotors but I am going to use the Mini Cooper S rotors but the bracket I have are the ones made in Japan.

Anyone know if you can use the Mini rotors on this type of bracket or do I have to use the EG rotors?

I was not sure about the disk thicknesses or offsets.

Thanks,

Blake

[ae86 drifter]

thanks mate for rehosting pics.

[44GTE]

Spirited Away

I have done a complete mockup with the mini cooper S rotor and Jap Yahoo brackets.

I had to mill approx 2mm off one surface of the caliper mount to centralize the rotor and also machines about 1-2mmoff the overall dia of the RDA rotor so as not to rub on the inside surface of the caliper.

Hope this helps

Cheers

[dori_86]

hey just some quick questions

how much would *I* be looking at for getting the adapter plate CNC machined by some1 300? instead of buying off some1

also is $300 for a a pair of FC calipers a good price? also the guy said something about these being better/special-er because of something like theyr off a aus FC or something?

cheers

[Oly AE86]

$300 would be ok, provided they are in great condition and don't require a rebuild.

Cheap places to look are Mazda forums, or Ebay for example. I got mine of Ebay US and were only $135 AUS Delivered (y) Just had to stay up till 2am to steal the auction ;)

As for brackets, from what people say, it is not easy to walk into a machine shop and have them make one set of brackets cheaply. The setup cost makes it $500 + hence why ppl are getting many sets made up at once to lower the price.

If you can wait a few more months, I think there will be some people offering bracket sets or even complete bolt-on kits for reasonable money.

[Sparkle86]

There is a guy on ebay that sells the whole set up from time to time I think $1300 with coilovers and the barkes. Probly a pretty good deal if you cant make them yourself. These calipers are pretty expensive to rebuild for some reason too, so if you get a set make sure they are in reasonable condition or you could be up for an expensive rebuild!

[Chrisso]

Does anyone have the hot tip on a rebuild kit part number and ball park price? Or have others just paid to get them done? My preferrence would be do it myself and save some cash, unless the difference is negligable.

Cheers,
Chris

[Oly AE86]

As mentioned on my initial post, my pair were $160 to rebuild which covered new seals, and labour for stripping them and cleaning/repainting them afterwards.

Because they are 4 piston unit the price could be higher than a single/twin piston set. I took them to a local shop (Brakes Plus) and he had them back to me the next day.

Dunno what the parts would be worth, but by the time you buy the seals, paint if need it etc it would add up.

I diddn't need any pistons, and he said they were great inside, even though they looked well-used on the the outside.

Oly

[turbo_rolla]

dunno if this will be of any use, but i was checking out yahoo auctions for some JDM brakes and came across this:

[SLO-030]

Just a quick thing i just noiced on the dba website is that the part number you have for dba its listed as a 280mm rotor not a 276mm rotor.

Other combinations have been done to. As im looking at setting my car up for two things and a 14" wheel is the biggest im allowed in IPRA i need brakes that will fit under a 14" wheel.

Looking at a few of the other corollas out there (ke20 mostly) they have setups like S4 rx7 calipers and rotors, S4 rx7 calipers and EVO 2 rotors.

Looking at the specs it looks like the EVO 2 disc is the one that will fit under a 14" wheel with a diameter of 276mm and a thickness of 24mm (requires a spacer in the caliper) BUT the center hole is 69mm and the height is 45mm (1mm higher)

Other wise if someone could tell me if the mini rotor fits under a 14" wheel i will go down that way if not then i will look into other opinions.

Why are you limited to a 14" wheel in IPRA?
As far as I'm aware, the majority of U2L front runners around the country are taking advantage of the change of rules allowing a 50 profile tyre for early models. As a result, the rolling diameter of a 205/50-15 is actually slightly smaller than the 195/60-14 that they were previously using, or the 225/50-15 gives a pretty decent amount of extra rubber on the track (but is slightly bigger than the old 14 if clearance is becoming an issue)

I for one am rebuilding my entire brake system - front and rear, to make use of the extra space the 15" wheel offers.
If you'd like a setup that fits under a 14, then I have a set of 4spot Volvo calipers on brackets to suit a KE70/AE86 strut with Ferodo DS2500 pads and RA60 Celica discs on custom adapters to bolt directly to AE86 hubs. All of which will be for sale once I get the Mazda calipers mounted up...

[Spirited Away]

^^^Hey Craig^^^

I just purchased a set of the DBA Mini cooper S rotors (276 diameter) but I did notice that the DBA pdf. catalogue was updated just a few days ago. Prior to that the mini rotors were 276 mm dia. but now they are 280 mm dia.

If you want to run the Mini cooper rotor, RDA still (I think) have the 276 mm version available. The part number is on the first page of this very helpful thread.

Also,

Does anyone have a fairly good idea how much the DBA mini rotors are? I was quoted $180 per rotor. But the RDA brand is a fair bit cheaper.

Thanks,

I've got a pair of those very same mazda adapters on my table. Copies will be available in a couple of weeks if all goes well. I just don't have a spare set of hubs atm to dummy fit and modify the bracket to suit a cheaper rotor option than the honda one.

will you have brackets made to run a slip-over hub FC rotor with FC caliper?

[beerhead]

I'd prefer to make it mate up the the back of the hub. I just need to bolt the adapters to some struts and calculate the height of the needed rotor. I've converted got the DBA catalogue to a database so I can make a list of exact fits.

[SLO-030]

Before i get mine made up i will also be working on using RX7 S4 rears aswell. According to the online DBA catalogue they use a 273mm daimeter rotor, 20mm thick.

I will be setting it up on an Fseries diff though.

[hahaboy]

this's my rx7 caliper.
i got the adapter made by Japaneses. anyone interested pm me.

Craig,

I would be interested in your progress on using the rx7 s4 rears as I have a set at home and have been considering trying to mate them to a T series diff I have. Before anyone jumps on me, it's a JDM diff so I can't use the corona set up without some modification, and I figure if I'm going to modify, then I might as well use what I have already.

A quick question for you. Do the rear brakes use an internal drum for the handbrake, and regardless, how effective is the handbrake on them?

Regards,
Chris.

Not sure, I haven't even looked at a pair of rear calipers. Couldn't even tell you if they were single twin or more piston. I was just going to use them because then my braking sysetm would be equal if i use the same size master and bias as the s4.

Handbrake i was just going to use a hydrualic one for drifting use. So that part didn't bother me.

Easiest way to tell about the handbrake would be if it has anything on the caliper that looks like a lever or something.

using mesh wheels now, cant see thru the caliper now

[ghetto ke]

hahaboy are you running a FC disk over AE86 hub with bolt on spacer to clear calipers with Mesh wheels?
What size and offset wheels are you running?

[Chrisso]

Craig. I'll pull out the rears I have at home and have a look at them and go from there. I will eventually put in a hydraulic system but require a cable jobbie to keep the thing legal. Thanks mate.

Chris.

This might be a stupid question, but I have a S13 master cylinder here with 3 holes on it instead of two like my ke70 one has.. Am I able to use it or do I need one only with two?

What else is invloved in fitting ?

[RussianMafia000]

really? I had another thread in the tech section and it said I could but only non abs models.
I had a look through the FAQ but couldn't find the info I was after.

What other easy options do people use? I've got large hilux rear drums and will have SR20 brakes on the front.

[RussianMafia000]

Ahh eyh I'm looking for something a bit cheaper if possible, this s13 one cost $75 but I don't think its going to work without a bit of modification to the lines.
Anyone used a landcruiser one?

[RussianMafia000]

Can you tell me what year model roughly it's from? Non-abs?
And did you need to use a bypass valve for the rear brakes?

It looks like the discs mount to the back of the hub because you can just see the edge of the hub and then it steps down to the bolt on spacer.

FC rear calipers do have the handbrake on the caliper.

Remember when doing rear disc conversions and master cylinder swaps etc to find out where your inline residual line valve is for the rear drums and remove it. Rear discs dont need some pressure on them like drums do.

Just a quick thing i just noiced on the dba website is that the part number you have for dba its listed as a 280mm rotor not a 276mm rotor.

Other combinations have been done to. As im looking at setting my car up for two things and a 14" wheel is the biggest im allowed in IPRA i need brakes that will fit under a 14" wheel.

Looking at a few of the other corollas out there (ke20 mostly) they have setups like S4 rx7 calipers and rotors, S4 rx7 calipers and EVO 2 rotors.

Looking at the specs it looks like the EVO 2 disc is the one that will fit under a 14" wheel with a diameter of 276mm and a thickness of 24mm (requires a spacer in the caliper) BUT the center hole is 69mm and the height is 45mm (1mm higher)

Other wise if someone could tell me if the mini rotor fits under a 14" wheel i will go down that way if not then i will look into other opinions.[/b]

Craig,

I was talking to Hen about this on the weekend and he was under the impression that some of the rally guys were running a magna disk with the rx7 calipers, all under 14"s.

hi.

did you happen to catch what magna rotors hen sad they were using? Ive got the same fc ally brackets and some civic type R rotors, although i havent tried to fit them under 14's, wouldn't be bad to know what part number to get if they dont :D

Hen didn't know the model that the rotors came off and just suggested that I get in contact with the guys. I believe it was Gillie from Toymods.

[Chrisso]

JHS - would you mind sharing the model of the magna? Save me having to look up the DBA database. :)

[Chrisso]

Thanks mate. I can chase it up. I was just curious and will, if/when I get the time, compare the dimensions to the civic disk to see what the differences are interms of both the disks and thus the brackets required.

[Benny]

Ipra only allows 14"???? That's terrible..

I have got fc brakes now uninstalled. Going with the ajps adaptor bracket and either project my or endless slotted rotors... What you think?

wat model rotors are u planning on buying?? EG civic?? do project mu or endless make rotors to suit EG civic?? personal opinion says overkill, but if u have money to burn and like ur brand name bits go for it

[RobertoX]

we will be suppling RDA rotors with the kits, but others are optional
