Geez. Thanks for the info. Sorry to be so long replying but my computer developed a bad power supply (I hope that's all It is) and the only access I have is to use wife's until I get a new one. She writes and so is using it constantly. Probably won't get to the truck again until tomorrow or Saturday. Then I will look at caliper first and take it from there. MC and booster were (I believe) from Rock Auto as a set I will look for more info today. Just to be clear, we are talking about the push rod that goes between the booster and the MC not the one from the pedal to the booster. Right? One other question. If the problem was at the MC wouldn't it affect all wheels equally or at least the front or back in pairs? Later. "She who must be obeyed" wants her computer back.
