Brake stuck on
My 16v recently developed a 'sticking' front off side brake. Initially it was staying on slightly after braking but then releasing again. However this developed into enough of a 'stick' to actually stop the car when free wheeling.
None of the other calipers are affected, just the OS front. I did the following to try and find the fault
1. Pulled out the ABS fuse to eliminate this from the equation, brake still stuck on.
2. Thought the caliper must be part siezed or have a score on the cylinder, tried to push it back with brute force and it wouldn't. HOWEVER, I opened the bleed nipple just in case and the piston went back with no effort, so nothing wrong with the caliper.
3. At this point could only think of either crap in the pipes/system or a faulty valve somewhere. We bled some fluid through this one caliper, and it did seem to aleviate the the problem, however the brake does still stick on, just not as much. Sometimes it release almost immediatley, other times it stays on for a couple of miles.
Bleeding the fluid may be a red herring, but before I go deeper and start taking things to bits, any advice would be welocme.
