Big Truck - Fixing Stuck Wheel and Adjusting Slack Adjusters on a 1989 Mack R600 Semi Tractor Dump Truck with Air Brakes.

In this video I show how I replaced the QR1 air pressure valve between my rear wheels, but then I had a stuck brake in the middle row of wheels. We got the wheel loose and then adjusted the slack adjusters on the brake to go back to proper function. This same slack adjuster adjustment is used on many brands of trucks with air brakes such as Mack, Freightliner, International, Volvo, Peterbuilt, Ford, Chevrolet, Harvester, Oshkosh, International, GMC, GM, Navistar, Sterling, Case, Oliver, White, Kenworth, and more.

You will need an 11mm box end ratcheting wrench to get into the tight spots and pull on your slack adjuster bolt: https://amzn.to/3qHBMex
