Ya know, I had a hunch the rear pads glazed over. Even though I sanded them down by hand, I dont think I did a good enough job. They had previously been in out of round drums (stupid us forgot to check them) and glazed a bit in about 200 miles or so.

Took off the drums-what do ya know, shoes are shiny. Took 60 grit sandpaper and sanded them down really well. Everything else appeared to be fine, no leaks or outof place stuff, compared to the FSM.

Then I took a drive. At first the pads needed to settle it seems as they werent releasing right. You could slam them home, let off the they would kinda stick. However after about a 1/2 mile of on and off, it went away and the truck stopped great. No vibrating or grinding and I drove around 45mph max and stopped hard alot, no issues. But only time will tell..

Checked the fronts, fine too..
