Okay, I replaced my vacuum pump since my pedal had been getting hard and it had been making noise. There's a long story here about me ending up having one of the wierd Jan-March 1992 pumps, but I digress.
I put on a remand Cardon pump, second trip out lost power brakes. Took it off today and the internals had failed. Got a new Dorman pump, put it on, and replaced all of the vacuum lines and now I'm losing vacuum at the booster. I can have it all hooked up, all the lines in place and only get 6 lbs of vacuum. I take off the line to the booster and plug it with my thumb and vacuum jumps up to 21 lbs. I replaced the grommet and check valve, same problem.
Is it possible the failure of one caused the other to fail, or is this just some twisted joke to fate that they both failed at the same time (or both the booster and the old vacuum pump were failing together)?
Anyone have any thoughts on this? the leak is definitely at the booster. I plan on taking it off tomorrow, is there a way to check it by hand beyond what I am doing?
Please help!!!
