Re: Brake Problems

[John Erk <johnny.erk@sympatico.ca>]

You're right about the master cylinder.I suspected this and had it replaced.They
still would stick. My mech.  assured me that the rod was in the receiving bore
of the master cyl. when he put it in. I'll try to verify this tomorrow. The
booster is stock however.
When at idle, I pumped the brakes very quickly and  the revs went up, and when I
stopped they returned. Is this normal or a vacuum related problem?
