Worked on Mack trucks. drivers would complain about not stopping fast enough.Quality shoes would wear the drums.
Biggest problem with drum brakes ( besides fade). They do suck till they get seated, which most trailer queens never get to. With QA. nowadays you will be lucky to get 50% of friction surface to hit the drum for the first 1000 miles.Unless new drums are used the shoes will need to be "arched" to match the radius of the drums to get full - proper- contact when braking
Yeah, I worked in one of those shops. We didn't know much about the asbestos issues then....Yep, every brake shop, major repair shop had equipment to arch shoes Back in the day. The asbestos dust must have been thick in those places.
Sure didn't. 4 wheel drum brake job. After removing drums what's next? Break out the air gun and blow 'um out.We didn't know much about the asbestos issues then....
Huh? WTF are you talking about ?No, stop, i don't believe you with the failures, BS. I have too many years of doing this, well connected since 1982 with a few clutch and brake remanufacturing companies. kma
