10"drums front and 9"drums rear, what master Cylinder use?
A disk/drum system would have a either a seperate proportioning valve further along the frame rail toward the rear brakes.
or a distribution block combining the proportion valve and safety switch. Its got a bigger bottom to fit the proportioning valve in, so that's not what you have there.
A car with drums on all four will not have a proportioning valve.
Cutaway of the safety switch from the same pamphlet as above.
That's just a distribution block with the safety switch.
