As explained before, I took over somebody elses project (32 Ford), he had a master cylinder already bolted to the frame, I'm going with finned Buick drums in front and stock Ford drums on the rear. The master cylinder he had mounted has a larger compartment fot the front brakes than for the rear, which accoring to what I've read is for a disc/drum combination.
What master cylinder should I be using for a '32 Ford with a drum/drum combination?
