Rear Brake Problem

[sturb25]

Ok, well ive got this problem where all of a sudden my brakes started to make this weird scrapeing noise and when i put it in reverse it had a high pitched squeal, i thought it may of been a rock jambed between my brake shroud and my disc.

Apon my investigation i found that one of my pads on the inside of the rear passenger caliper was worn down to the metal and the other side of the pad still had 2-3mm of pad left. I figured out that the bottom locating pin/guide pin on the caliper support/caliper bracket had seized and the caliper support was not moving or releasing on the caliper body as it should, thus wearing away my pad severly on one side of the pad.

I undid both caliper locating pins and got them both turning and put it all back togther, replaced all 4 pads and pumped the brake pedal a few times to get the pads to come in on the disc. As i was doing this i heard a clunk come from the back disc that im having problems with. Thought nothing of it and went for a short drive around the block. Got back and all i could smell was burning brakes. My back brake must be locked on.

Is there anyone has has experienced this problem and know how to free up these locating pins?

Take it to s brake place. They are a sliding caliper, and need one to pull the other on.
