You must disassemble the caliper to find out. It sounds like you have air or moisture in the hydraulics. As the slightly dragging caliper heats up, the air expands, locking up the caliper. The crud built up in the caliper is preventing it from retracting. To do it right, buy all four caliper kits and rebuild them all. Then, to keep it from happening again, CHANGE YOUR FLUID EVERY YEAR. To prevent damage to the master cylinder, bleed with a pressure or vacuum bleeder.

I took my rear caliper and rotor off and they seemed ok i guess so i put them back on and tried to drive my car agai. I think my rear calipers have gone bad and im wondering what are some signs when this happens? When i pump my brakes when the car is on the brake pedal seizes up. Its the same thing as if you just keep tapping the brake when the car is off and the pedal stiffens up. also if i drive for a couple minutes the brakes start to stiffen up and the car will come to a stop. i have to wait a couple hours before i can drive again. any ideas? thanks
