“Just bought this truck from hubbard trailers, in arizona, with a receipt from having both rear brakes redone. Drove it home then took it to the local fl dealership (nampa, id) to get an official inspection. On inspection the ABS and brake lights were on. Work was done, and I was told everything was fine on the truck re:brakes. I drove it home, about 30 miles and no problem. First time I tried to take it out on a trip, the rear caliper locked up. Called nampa Freightliner, multiple times, while stopped on side of road. They advised to bleed the brakes, which I did. …”
NHTSA complaint #10910910, filed 2016-10, 133,000 miles“The Freightliner tractors we are now using at yellow transportation, in nationwide service, have a problem with the foot brakes. The brakes, when applied, are very slow to release. I feel this could cause a serious problem on slick surfaces. We usually pull twin trailers behind these tractors--and they are sleeper cabs, two man operation. The brakes will often drag the vehicle to a stop, even when no pressure is being applied.(as when coming to a red light-the light changes,brakes are released, but the vehicle continues to slow and will come to a stop).”
NHTSA complaint #10079129, filed 2004-07“(1) design (2) parking brake allows vehicle to move as much as 4 inches after setting. Unable to hook-up trailer without 2 people. Damaged hitch. (3) Freightliner claims it can not be fixed.”
