Rear brakes locking up

[scscomp]

I fought this problem for a long time before I found the solution. I had recently replaced the rear shoes with semi-metallic lined shoes. The rear brakes are designed to lightly scuff the drums when turning and the higher friction semi-metallic lining material was overheating and warping the drums. Even if you adjust the shoes to not scuff the drums, the shoes will self-adjust back to the scuffing position after you back-up a few times. The solution to my problem was to replace the rear shoes with organic lined shoes (probably what the original linings were). I turned both drums to remove the warp and the problem was resolved. Now to figure out what to do when they stop selling organic lined shoes.
