Hi all, My truck is doing something strange I haven't experienced before. Its a '95
1500 2wd. The brakes work fine on the first pump, but each consecutive pump has less and less power assist, until on the fourth or fifth pump it has fully manual brakes. Not exactly a fun or safe situation. After driving another 30 or 60 seconds the power brakes will be recharged for a pump or two.My guess is a leaky power-brake vacuum diaphram? Does that sound right, or might it be something else?
Thanks a lot, Brian.
