After 2 weeks in the shop, the front brake problem my truck was having, has been remedied as of late yesterday. The technician told me he adjusted the rear brakes as well. I put the truck on the highway today and within a few miles I could smell brakes burning. Oops! After stopping, there was much smoke coming from the right rear brake. A bit too tight I'd say! I had the truck towed home but the brakes are so tight, it is like trying to drive with the parking brake fully set. So at this point, my truck is not drivable. My understanding is, the brake adjustment wheel will only turn in one direction, tighter. I need looser not tighter. Can anyone tell me how to back the rear drum brakes off so I can drive the truck? Your help is appreciated.
