    Can anyone recommend a master dual chamber M/C for my model A ford juice brake conversion? I was told that my mid 60,s mustang m/c was to small for the early ford wheel cylinders.

    Early Ford M/C is 1&1/16 bore and fed 4 wheel cylinders. What is the bore on the Mustang M/C? Each half of a dual feeds only 2 W/Cs so even 15/16 M/C bore should work OK with a very easy pedal.

    Is your M/C going under the floor or on the firewall? What brakes are you using?

    On my old 1951 F1 with stock brakes under the floor, I used a 1969 Chevy 1/2 ton pickup M/C. Had to redrill the mounting holes a little inboard to work with the F1 crossmember.

    The Mustang manual MC bore is 1", and should work just fine.

    I just swapped out a 1" diameter mc out of late 60's gm w/ four drum to a 1.125" diameter late 60's gm with disc/drum. Work great. The best pedal I have ever had w/ 40 ford brakes.
