Very Hot Nearside Brake Disc

When I say HOT, I mean glowing red under normal driving conditions with smoke coming off the brake pads! with the offside disc at normal warm temperature under mild braking conditions. The caliper pistons were sticking and have been released, ok for a couple of weeks and problem reaccured. The brake disc appears to be straight so I do not think that is a problem. The vehicle is not pulling to one side and stops in a straight line ok. Would be very gratefull for any ideas before I replace complete caliper.

ya pistons/seals is fooked. Strip em out and fit noo pistons and seals.

I would say check tc incase it's sticking that wheel if not new caliper ibthink

I had this on my Peugeot, had changed the calliper only a few months before so knew it wasn't that. The flexi-hose to the calliper had collapsed, so for a few quid buy some new hose and change that first. Cheaper than a calliper!
