Hydraulic handbrake with stock rear brakes

[fax0815]

Hi, can´t complain about the AE86 rear brakes? You´ve done everything right, 0.625 cylinder is perfect for most cars.
I´ve had the same setup for years, and they have always worked excelent, how´s the condition of your discs/ pads, if they are old rusty or really worn that affects the performance of the handbrake.

But I´ve also rebuild the calipers a while before I fitted my handbrake, the self adjuster was seized on on side, so they were adjusted uneven and didnt work properly, that might be worth a try?
