caliper sticking?

(1/2) > >>

AndyBrown:
Few month back my car failed it's MOT on a rear caliper sticking, was making a squeal when doing a slow speed and gentle breaking. Replaced the rear caliper passenger side.

Got a squeal again which seems a bit worse this time, car doesn't pull in any direction when I'm braking, just a squeal when going slow, so ive got a few questions.

1. How can I check if a calipers sticking?
2. Is it possible to fix without needing another new caliper?
3. Would lowering the car affect it as I've had it done this afternoon and seems to be worse.

Thanks

If a caliper is sticking on then the disc will get very hot after a run. Touch it very quickly with a wet finger and see if it boils/hisses.

AndyBrown:
Bit more info, seems to be fine when the brakes are cold, if the cars left for 5 mins or so it's all ok, no noise at all.

I get the some problem when driving a low speeds and braking gently I get brake squeal from what I believe to be the front left. Could this just be oil, grease on the surface of the disc? Was thinking about taking my pass out and deglazing them. Also the car has just had a MOT and no mention of any problems with the brakes

AndyBrown:
Anyone got any ideas?
