Question #1: did you buy a disc/drum master cylinder OR did you buy a drum/drum master cylinder? Discs dont like drum master cylinders.

Question #2: Did you bench bleed the master cylinder?...this means that you bled the cylinder before the tubes were hooked to it....preferably on the bench so you dont get juice on your car.


---I bought a disc/drum master cylinder
---I did bench bleed the master cylinder


The spindles were used off the gran prix, everything else I bought new for a 72 gran prix.

Should I buy a new power break booster also? The one I am using is for the origional drum breaks.

Thanks again for any help, Bob
