i change the brake fluid which fixed the brake faid i was getting. i got new rear pads and unfroze one of the rear calipers. now the rear brakes are rubbing really bad. today i went for a short drive and was really easy on the brakes. i stopped the car and got out and i could feel the heat comming off of the rear brakes with out even touching them. i checked the front ones and they were slightly warm. after taking a longer drive the rears get so hot that they start to howl really loud when im starting from a stop. any ideas on how to fix this?
The caliper is frozen... or seizing. Do what E said and rebuild or replace the caliper... Its really just the piston that isnt going back into its home
