Disc/Drum Master Cylinder

I'm running manual disc front/drum rear brakes on my Fleetline build. Speedway sells a 1" bore M/C that does not need proportion valve. I have one on my avatar car, and it works great but I don't remember the GM application. Does anyone know what year and model GM unit accomplishes this? Speedway advertises theirs as Corvette.

 

refer to brake handbook by Fred Puhn. engineer to win by Carol Smith also deals with engineering braking systems.

 

The master cylinder by itself does not determine the need for a prop valve, rather the vehicle and brake system.
Speedway does sell a chrome 1" aluminum master that is the same size as a Corvette, and features adjustable proportioning, removable metering, etc.

 

Manual Disc/drum and drum/drum master cylinders are available at your local NAPA, CarQues, or O'Reilly's parts stores. If they don't have it on the shelf their local warehouse will have it there for you in a couple hours or the next day at the latest.

 

here is the master and distribution block on my 1978 chevy pickup.

 

I would use one. HRP
