Re: Proportioning Valve ?
Doug - Thanks for the reply, Yes I measured the depth of the master cylinder to the mounting surface and then made sure the rod was out from the power booster that distance, with about .060 clearance. I fine tuned it by pedal feel after that.
Tim - I think you are on to something. The 67-68's when they had disc brakes, there was a proportioning valve added. My 69 does not have a proportioning valve, so from what you are saying is that the 69's are different and it should have a residual proportioning valve in the master cylinder. This would answer my question and not all 67-69 Camaro's use the same master cylinder as the parts books try to tell you. To fix my problem, I think I will just install the PV-2 proportioning valve and remove the distribution block. The car is far from stock so I am not concerned with keeping it original. GM even went back to a proportioning valve on the 2nd gens, I am thinking in '71 ? Also, I have stainless steel flex lines, so no all rubber hoses.
Thank you for all your help !
