Hi Al,

T6 aluminum can begin to lose it's temper and strength at 400 deg F, pyrolysis of the tire rubber begins at around 475 deg F. Tire rubber will vulcanize at around 350 deg F. The trick is estimating how hot the tire got. Generally anything over 200 deg F is hot enough for tire damage. Aluminum and rubber don't like heat, your steel will fare better.

I had a similar situation with my LXi right after I bought it. The right side tag axle brake hung. I had mechanics replace the brakes, drums, rollers, etc several times, but the problem persisted. I finally fixed it myself by replacing the slack adjusters. Remember that brakes should be done in pairs, both sides of the axle at the same time, including slack adjusters. I believe you're running Crewson Brunner slack adjusters. I can get you a part number in a minute. Automatic slack adjusters are finicky, the installation has to be correct and the brand needs to be the same on both sides of the axles. Mechanics mess them up by adjusting them manually.

Al, during our WaGu rally I mentioned that your brakes consumed excessive air pressure. Sitting in your driver's seat I applied the brakes and the air pressure dropped greater than 12 psi which usually indicates out of adjustment slack adjusters. Did you have anything done to the brakes since then? Were there mechanics monkeying around with your SA's?
