Dear all,
hi, since a couple of days ago i've got a sticking rear brake problem on my fiat Stilo from 2005. first i noticed the sticking rear brake pads moving the car after standing still for 2 weeks with hands brake on.
i thought it would be a temporary issue, but i see that the problem remain. you can feel the brake disk is much warmer than all other three wheels brake disks.

after alot of google search and couple of youtube videos, i tried first to disassemble the calliper and clean/lubricate the sliding pins which didn't help. then i bought a whole calliper assembly from salvage yard, and replaced the the whole thing, winded the piston back (which was hard to wind with the proper tool), bleed the brake, but still no improvement. i thought the brake hose may be an issue, but i see with bleeding that plenty of fluid comes through...
somehow, from the first time brake after install, the piston fail to retract and the whole thing get stuck!
i really dont know what reason can be. of course there is a chance the second calliper may also be dead but the seller says that they test the parts and they works and they give three months guaranty... i can buy a new calliper but i wonder if that would solve the problem, and of course i try to avoid unnecessary costs. i checked the ECU for error, there are no faulty errors on engine ecu or ABS system either.
i wonder if there are people with similar problem who wants to share their experience. what blocks the oil in the brake to go back and the piston fail to retract after releasing the brake (hand and foot-brake). could it be a failure in abs system (drain valve) and is there any way to check that out since there are no error records?
anyway, any help will be appreciated.

best regards

Possibly the handbrake cable seized, or partially seized.

thanks for your tip, i thought first too it might be the handbrake cable, i unhook it before with no effect. i think it must be still the calliper itself. im going to rebuild it and lubricate it to see if it has any effect.
i'll let you know what happens.
bestr egards,
Far.

i had issues a little while ago with my brake calipers, in the end i gave up and just purchased a refurb, problem went away.
In my case the spring on the handbrake was not strong enough or it was too seized to return the piston when releasing the handbrake.
i lubbed it and it was fine for a few weeks then failed again (car was rolling away when parked).
If you have prooved the handbrake cable is ok just get a new caliper it will save all the grief in the long run. I would also think the one you got from the breakers is as bad as your original if it was tough to return the piston, once they start going they should go back with only little force if the using the correct tools.

Cheaper caliper. plus 2 year warranty/ they do both sides.

when you clean and lube the pad sliders if you have not done so already is also worth checking and cleaning the caliper/pad mounting bracket so you do not have a build up of old rust that the sliders fit onto the mounting bracket and so making the pads a tighter fit on the sliders I have had this in the past and once scrubbed up the mounting bracket aides the pads to move more freely on the sliders and not become a little wedged in place when the pressure on the caliper piston is released.
