73 Mike
I'll drive it someday
I was finally able to get the hydraulic unit for the hydroboost in on Sunday. Lost the clevis pin, but that is another story :cussing:
Having read a paper recently that suggested "dry fitting" the master cylinder before priming, I put it in only to find that the old one was plumbed in reverse to the new one. Let me try to explain clearly:
Old MC: Large MC plug (5/8 X 20 I believe) in the back going to the rear wheels. Top port on proportioning valve. Small plug and line to the fronts ( 1/2 X 18?). Bottom input port on proportioning valve.
New MC: Large MC plug (5/8 X 20 I believe) in the FRONT. Small plug ( 1/2 X 18?) in the back.
The car is a 73 and hydroboost requires a later MC or a spacer bar in the booster shaft. My old MC was bad anyways so had to replace it and went with the newer model.
My question is, which is right? Should not the larger fitting and line go to the front brakes? My brake booster was certainly not original so there is no reason to believe that the MC was. The lines look original but could certainly have been switched around.
