Brake Upgrades.

[ArJay]

Had a decent look thru the forum for a thread detailing all the different brake combinations and upgrades for the 86 and couldn't find much.

Know most of you boys are more concerned about going sideways than deep braking but thought it'd be good to start up a thread maybe compiling all the different options avail. There's a few of us out there who're interested in doing some circuit stuff so this'd be great info to know...

The only ones I know/ heard of so far are

ADM JDM swap.... ventilated? Straight swap?

RX7 calipers and rotors...not sure whats needed as far as a adapting these. Anyone got any info/pics?

S13 calipers and rotors... to quote from a post by omy in this thread. (http://www.ae86drivingclub.com.au/forum/index.php?showtopic=4210&hl=).

Ok, the S13 brakes use the std AE86 struts with the std brake brackets that have been moded to locate the calipers. As the s13 disk is free floating like most other setups, you will have to mill you std ae86 hubs down by 12mm so that the disk will fit over the hub. The wheels are what holds the disk in place. Most of the pics will explain this, the setup will come with every thing to fit, all that is needed is to machine the hubs down and maybe longer wheel studs.[/b]

Anyway bring it on... what have you got/seen and how's it done!

ADM TO JDM, the most simple one and cheap......$600-$650 full set heaps better than the ADM ones

RX7 calipers and rotors....Will need the adapting plate and bigger rims...around $1000 set

Depends on how much u wanna spend http://www.ae86drivingclub.com.au/forums/emoticons/biggrin.gif

[rthy]

$600+ for a wimpy set of 230mm vented JDM rotors? no way.

I could be wrong but I think the struts and brakes of a ra60 are a bolt in with no camber change. They are 256mm vented rotors with a massive caliper. They are the same as the celica supra infact which is what I am using.

[RobertoX]

the ra60 stuff is junk,

there was a massive thread on here about it

heavy and pos camber etc

hachis really dont need big brakes with NA 4a

[3sglevin]

I have RX7 calipers and rotors on the front of my car, they are good. I have been using them for circut racing for 5 years and they have been pretty good so far, I am changing them for the new car but not cause they dont work well.

I have a custom bracket, standard RX7 rotor, and caliper all under a 14' wheel, so you dant need big wheels for good brakes. When i get a chance I will post some pics of it

RA60 struts n disk > RX7 4pot calipers + EG6 disks > Stock ae86 adm disk

the 86 spring fits in the ra60 strut, will need the knuckle/idle arm, just use the ae86 strut hat and tops

[slydar]

as dave mentioned, using ra60 struts in an 86 is a bad idea. the geometry is all wrong.

the stub axle angle will increase you + camber which you could argue could be corrected with longer LCAS, but there are other consderations, like steering knuckle lenght and ackerman angle. if you know enough to know in which way you want to change these other variables to produce positive results, then maybe consider a strut swap, but if you dont, youre much better off sticking with your original strut casing.

unlike the ra60 struts, the 86 strut has a removeable caliper bracket, which affords you alot of freedom in brake upgrade design.

the jdm swap is a good idea. is it fade your trying to get rid of? or do you want more power? if its just fade and maybe a little more power get the jap stuff, the vented disc takes care of the fade and a nice set of pads can give you a bit more bite. it is bolt on too and keeps the unsprung weight down.

for an NA 86 that is only ever going to see road/some light track work, i would say the JDM swap is a good choice.

[ArJay]

Awesome, cheers for the info boys...

The power is fine and will only be doing 6lap sprints so it's mainly fade that I'm worried about. The JDM swap is sounding better and better...

Here's Bill Sherwoods RAV4 disks with willwood calipers...disks are 308mm tho and he's running 16s to fit them under. Looks like he's running a custom coilover as well tho.

Question...with the JDM swap what do you need to swap. Just disks and calipers?

R:)

[slydar]

yes, you only need the discs and calipers. infact if youre really desperate you can run the disc only, and have you pads milled down to fit. i wouldnt recomend it though..

but yes everything is the same only the caliper is wider, to accomadate the wider discs. they use the same pads too.

[ArJay]

Sweet....thanks slydar. That's good that the pads still fit cause I wasn't looking forward to forking out for good pads again.

What about the master cylinder etc...all the same as ADM?

And does anyone know about the pug/corona setup? Heard about it a few times as well....

Cheers
Rory:)

[biggo]

Rona struts + Pug discs + hilux calipers apparently bolt together.

Head that you are supposed to mill the discs to fit under the lux calipers. I wouldnt know tho as i havent done it http://www.ae86drivingclub.com.au/forums/emoticons/tongue.gif

IM goin ra60 discs+cailpers modded to fit stock hubs. One of the reason i didnt just get the entire strut setup of the sleeka is because of the weight. While many people say it wont be much, i have to do everything my self and had a hard time lifting my shitty stockos!

[biggo]

he hilux (LN106 4 pot) calipers bolt to XT130 corona struts as they share the 90mm bolt spacing for the caliper mounts...[/b]

Copied from the old toymods i think....just found it on me puter http://www.ae86drivingclub.com.au/forums/emoticons/tongue.gif

[AE86GT]

What size rims would you need to use the rx7 calipers and rotors?

$350 Calipers, $320 pair of new RDA Slotted Disc, $150 new pads, = $820 sounds reasonable?

[Course_Out]

I've heard that you can use ae92 calipers. Is that true? And is it worthwhile, cos I imagine it would be much cheaper than the jdm setup

[DavisJD]

Dont have any technical info for you, but just though id give you some stores that sell different discs, calipers, pads etc for you to have a look at. You might already know about these sites and there stuff but just incase you dont

This is interesting....from Club 4ag.


* Brake upgrades - big calipers

One thing most people neglect when describing braking systems deficiency is maintenance of the OEM units. True in the most grueling stages of track driving, the brakes on the Corollas in particular fails to deliver. However, in many cases and for most drivers, even those who visit the track often, overlooks the potential of the OEM units. With fresh re-build or replacement of the master cylinder and calipers, stainless lines, the AE86 in particular can stop very impressively using performance pad upgrade alone. And the feeling is night and day when the OEM units get proper maintenance. With larger modified rotor/caliper upgrades, the brakes will also require re-proportioning for the front -rear bias, as well as in some cases master cylinder upgrades. This latter step requires lots of track time and pad selection becomes key in further balancing your brakes to satisfying levels. What this presents is that you now have to deal with many sets of pads to find the right one and much track time to figure out your bugs. In any case, the brakes are what ultimately stop your car in a CONTROLLED manner. Please be very cautious and employ the skills of qualified tuner to figure on what you need to do, otherwise you'll be exposing yourself to serious danger, possibly without an once of fun factor.[/b]

The JDM option is sounding better and better and like Dave (Truenosedan) said before in most cases (mine included) we're talking about an NA 4ag which may not warrant bigger brakes.

I'm just looking to do some sprint meets in the future so really I'm not after that much more power, it's mainly the fade that i'm trying to reduce. Especially here at Mallala where it's "like a fight in a carpark" as one of my mates puts it...

Anyone got any experience with the JDM brakes as far as track work is concerned...?

[RobertoX]

speak to jack cuu from qld - funkdoc on these forums

[sr_rolla]

I used Hilux 4 spots (LN106), corona hubs and struts (xt130) and Peugeot 604 rotors,
you have to file out the mounting holes on the rotor and slightly file out the caliper (you'll see where if you do the conversion, to hard to describe, especially whilst drunk http://www.ae86drivingclub.com.au/forums/emoticons/rolleyes.gif ).
put some 1mm spacers between the caliper and the strut. If you want, convert it to hieght adjustable coils at the same time or else you have to get springs made to suit the corona strut and sprinter top.

Looks something like this...
[attachment=2997:attachment]
Also, if you go to 4 spots you have to get a bigger master (15/16" or 1") apparently mitsibishi starion master fits but im not sure, I converted my booster to 4 stud instead of 2 and used a MA61 Supra master.

Hopefully this helps http://www.ae86drivingclub.com.au/forums/emoticons/wink.gif

[PLACEBO]

Thats orsum!

What coilovers did you use?

[sr_rolla]

I used 350lb King Progressive springs, cut down the struts to suit SV21 Camry strut inserts and used noltec weld on hieght adjusters http://www.ae86drivingclub.com.au/forums/emoticons/2thumbs.gif
(note: when I did my conversion, i also put a RA60 diff in so the rear drums are larger, the 15/16" master works well for me but it may note for you, You have been warned)

ArJay - There was a feature many moons ago in Auto Salon magazine on a a few 86's (ae-xx was one of them) and there was an Initial D replica that apparantly used ae92 calipers. The article went into absolutely no technical detail, being Auto Salon magazine.

I'm thinking even a set of Aus spec ae86 brakes would be a decent upgrade of rmy ae71, the brakes on it would look undersized on a mountain bike!!

[rthy]

the adm ae86 brakes are like 2x bigger (in surface area) to ae71/ke70 brakes :S u will need the whole strut to upgrade the ke70/ae71 2 ae86 tho

[PLACEBO]

Do you find them good enough?

[rthy]

anything bigger than the ke70/ae71 is good enough lol

[johnny_08]

just go down to a peformance brake shop and get slotted rotors and ebc black like me http://www.ae86drivingclub.com.au/forums/emoticons/biggrin.gif

[Philbo]

Just to throw another option into the mix.

I have the following brake combination in my sprinter
Rear-Hilux diff, MA70 discs and calipers
Front-MA 61 struts shortened with coil over mod, RA60 bottom control arms, sprinter tops, MS65 hub, GA 70 disc and caliper with fabricated adapter plate
Master cylinder-converted sprinter booster to 4 stud to take GA 70 master cylinder.

Good points-Engineer happy, brake bias factory, and 5 stud conversion gives me the choice of huge range of Ford and toyota wheels. Stops brilliantly using factory pads, absolutely no fade.
Bad points-extra unsprung weight, bigger wheels needed.

Why? 1GGTE with W58. Bought half cut so I might as well use as many parts as possible. The only fabrication i had to do on the brakes was the adapter plates for the brake calipers and the 4 stud conversion on the booster

[gottago]

go S13 lower control arms with s13,s14,15,r32,z32 disks hubs and rotors. i used t3 tops and any s13,s14,s15 suspension with ether s13,s14,15,r32,z32 master cylinders it all fits dont understand why everyones trying to convert everthing when it all just about bolts up all you do is drill 2 holes for the sway bar get different nuts and bolts for the lower controll arms and bobs your uncle massive brakes coilovers more track mine cost less than 500 to do big emprovement all i have to do now is ajust the handrake cables or change the bias valve and the thing stops on a dime

[ArJay]

Cheers for that...

Have you got any pics of the setup? Will have to look into this further as it sounds like an awesome alternative...

Do the lower arms bolt straight up to the 86 mount? Why new bolts and nuts etc?

What about the strut bar? Do you need to drill holes for it as well?

[ArJay]

Brilliant!!!

Thanks VeRm... answers all my Qs.

Sounds like the S13 arms will give mondo camber if theyre bolted straight up. If they're longer than sigma arms then might be too much... have to look into the alternatives perhaps.

Great thread. Cheers for the link...

[anastasios]

yea i have just finished puttin ra40 lcas in an 86 and i would recommend using sigma gh instead, the ra40 is weaker and more likely to bend under loads with increased camber and track whereas chrysler is alot stonger http://www.ae86drivingclub.com.au/forums/emoticons/2thumbs.gif
