I had taken my truck in for repair as the the brakes were making noise and slow to stop. When I picked up the truck I was advised that the brakes were not in need of repair but instead were cleaned and adjusted. The receipt read: "Remove dual rear wheels, inspect shoes, drums, wheel cylinders and hardware, replace and torque to specification". A few weeks later the rear brakes seized and caught on fire on the highway necessitating a tow for the truck and a horse trailer. The brakes had to be drilled off of the truck and the truck required new rear brake shoes, wheel cylinders and adjustment. I was told my the mechanic that the linings were paper thin. My question is- what did this first shop do wrong or not do at all?

They may have adjusted them to tightly or something in the self adjusters kept making them tighter. It is highly suspicious at the least but hard to prove anything. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

After a couple of weeks worth of driving before the incident; I find it hard to believe they were adjusted incorrectly; with-in the first 10 or 20 miles you would have felt/smelt/seen something. I have seen the self adjuster(s) do this and don’t ask me why? It just happened to us on a 3500 GMC G van; we did a complete rear brake job; it got everything except drums (they were machined); about 6 months ago. Last week the driver came in with smoke rolling out of the right rear drum. Pulled it apart; thinking I was going to see a failed axle seal or the bonding of the friction material had come off. But there was nothing visibly wrong other then you could see that the new adjuster lever had a worn mark on it from trying to ratchet the adjuster wheel? Everything was in place; the parking cable wasn’t over tightened, nothing? We replaced all the heat damaged components, machined the drum and sent him down the road; still not knowing why? This part I’m only speculating on; this is a new driver (one week) with this company and he’s on a route where he has to back into a lot of loading docks with this van. If he’s a nervous two footed driver (especially backing up); it could explain why the adjuster got such a work out? Back in the 80’s when full sized rear wheel drive Chryslers were the norm as taxi cabs; we would purposely leave the adjuster levers off. We blamed the constant stop & go and backing up that a cab does for the adjuster to walk themselves up and lock the wheels? Dan. Canadian "EH"
