ive looked at the handbrake and wound the pistons out ever so slightly, now if the car is on my drive after about 5 clicks i cant push it back where as i used to be able to (my drive is a very slight hill) if its up on the jack after one click with some force as im a strong git who does weights i can spin the wheel slightly, the 10mm locking nuts on the ashtray are about halfway down the handbrake cable thread and not at the top of the thread, also when driving at a slow speed, i pull the handbrake up the back wheels wont lock? both rear calipers are new recon units. rear brakes were perfect
