well this is giving me a headache the last while, The handbreak never worked properly on the S15, few months ago I got the finger out and took a look and the handbreak cable was shagged, so bought working cables new pads and disks, fitted everything now I have the handbreak tightened to the last at the handle blead the system and still it just barly holdes the car when its parked on a slope, I think I'm looking at stiff pistons in the calipers but thought id post here incase there is something I'm overlooking, and if stiff pistons are the case anyway to free them? Or just replace them?
