ae86 disc rear hand break adjustment ?

[AIROCOBRA]

Hi Guys ,
Hope someone has had this problem and can shed some light?
Just put a JDM disc rear in my sons AE86 and can not get the hand brake to work ? Have a track car with same rear end and it works fine and have compared both and can not spot a difference.

Here is the story so far !!!!

- calipers have been rebuilt by brake shop
- cable checked against a new one no difference
- cable mounting checked with regard to track car no difference
- caliper piston screwed out to rest against pad , DISC nice tight fit when caliper is attached.
- spacers added to in cabin adjuster ( same as track car ) to get more leverage.

But after doing all that , hand brake is full on after 3 clicks , but hand brake does not hold the car at all. When hand brake is pulled the lever can be seen to move , but it is not able to apply enough clamping pressure. The foot brake side of things works perfect , good pedal , correct bias --- JUST NO HAND BRAKE ?
What have I missed or done wrong ?

Give that a go - it made a reasonable difference to mine (after I failed rego due to shit handbrake!)

I half followed that link and now my hand brake half works.. So i guess when I have time to do it correctly my hand brake should work correctly.

Thanks to those that responded ----- problem fixed . Pulled the hand brake mechanism out and found that it was out of alignment ( bent !) . This was causing the cable to bind up and the more I ADJUSTED it ( put extra spacers in ) the worse I was making it bind . Previous owners may have been a wee bit aggressive on application now and then ? Rummaged through the parts bin ( never throw ae86 bits away -- you never know ????) So replaced the whole hand brake lever mechanism with an other unit and wacko we have a hand brake.

Cool.

You should never adjust an ae86 handbrake at the lever. Its just there to set the number of clicks you like till full application. Always wind the pistons back into the calipers when it stops working and rebleed it. Its the only way. Having run this rear end for a few years now, about every 6 months you will need to do this. New cables, spacers and extra adjustment at the handle wont help it any.

^ Truth. I probably do it every 1-2 months when I'm using the car heavily.

Doing this again today actually. I got an old grinder tool that works well as a piston winder.
