I did a complete rear brake, front brake, proportioning valve, master cylinder, and wheel cylinders last month. 150 miles already. Last night I drove it to my buddies warehouse to adjust the rear brakes. The rear wheels were really loose so we adjusted them until a slight drag. Did not over tighten them. I drove home about 25 miles and pulled it in to the garage. When I got out of the car I smelled brakes and noticed a lot of smoke coming from the right rear tire. I did not drive with the e-brake on. Today we pulled the right rear tire and drum off. The drum was hard to pull off. Everything was cooked. When we stopped on the brake pedal with the drum off, we noticed that the forward shoe was moving but the rear shoe was not. The wheel cylinder was not pushing the rear shoe back or forth. We stopped and left it alone and walked away. I was very frustrated. Does that sound like a frozen wheel cylinder?
