Answer
Hi Cindy -

Looks like the wheel cylinders are freezing up on you. Either that or the proportioning valve is defective, but that hardly goes out.

Have a competent mechanic check both rear wheel cylinders. This is the part that applies pressure to the brake lining to press against the drum. When you let go the brake it seems like it is not returning. That's why it heats up.

Hope this helps -
