Hi,
I have a problem with my '71 vans brakes and hoping someone more knowledgable than me can help me out, I've searched the forum but can't find anything relating to the same fault.
My problem occurred today when I went to reverse the van from the garage after a few months of not moving, after a few feet the brakes appeared to seize up and stop the van, no matter how many rev's the van wouldn't move, the brake pedal was rock hard. When I turned off the engine the brake pedal appeared to soften and the van could be pushed freely! When I started the engine the same thing occurred the brake pedal went hard and the van wouldn't move, I disconnected the vacuum pipe in the engine bay and the van drove normally but with harder to work brakes than normal (as to be expected with no vacuum pipe attached)
When I first got the van I replaced most of the brakes with the servo being a new German Ate one at great expense!!
I'm stumped as to what is happening and hoping someone has an easy answer, clearly the fault appears to be servo related but I thought when they failed your brakes got harder to work, I can't seem to figure out why it's firmly applying the brakes?
Thanks in advance, and sorry for the long post...
