Question1984 300DT, 84,000 miles.... I'm original owner and have kept this vehicle well maintained, but recently I've noticed brakes appeared to be partially applied on rear after stopping. After examination, this was the case. I loosened one of the rear bleeder screws and got a squirt of fluid after which both rear brakes released fully. The fluid has always been kept clean and was recently changed, but this is did not fix the problem. By the way, this just happens off and on, not a constant problem. It's affecting the rear brakes only, no problem with the front. Thanks.
AnswerI would replace all four of the rubber flex hoses, retest the vehicle, if the issue remains, replace the master cylinder.
