Sounds like the rod between the master and booster needs adjustment. Did you buy the master and booster from us? We had a few master cylinders that were shipped wrong from the facctory where I buy them. Check your master cylinder where the rod engages. If the plunger is inset about an inch inside the master cylinder then that's the problem. The rod from the booster isn't long enough to engage the master cylinder. You will need to lengthen the rod. Give us a call if this looks like the problem.
