need a pic of master cylinder with manual setup

No, not stupid, you just haven't done a master cylinder conversion yet!!!


The master cylinder has a plunger, or rod that extends from the firewall side of the master cylinder to the brake pedal. As you apply pressure to the brake pedal, the plunger pushes brake fluid to build hydraulic pressure to all four wheels to activate the brakes.

If your car was a Disc/Drum you should have a proportioning valve in the system. It allows greater pressure to be applied to the front discs since they take more pressure than drums. It will need to stay or your rear drums will lock up before the front discs. My original Kelsey-Hayes proportioning valve was leaking, and after trying to rebuild it, I decided to buy a new proportioning valve from Summit.
