Rear brake problem, new discs and pads last october, working fine till now 1 rear brake rubbing getting hot and squealing to a stop. Took caliper off rewound piston back in all free as it should be, but back with squeal again after a few miles.
Has this anything to do with handbrake or have you had a similar problem.

The caliper is probably siezed on the guide pins. You might be able to free it off by proceeding as above, and bashing the caliper along the pins and back a few times with a wieldy hammer and a blockof wood, or you might need to dismantle and clean and copper grease the pins.
