Master Cylinder

[vht]

I got my system done but would like some info. My plymouth has the Speedway front GM rotors and the calipers are like the 76 malibu takes. The rear is an explorer with the factory disc brakes on it. What would you all think is the ideal MC to use on it? Now I have a dual reservior GM with the bolt on top. I put a corvette style on it first and it was junk, rebuilt, so I had this one on the shelf and stuck it on there. Haven't got to drive it yet but I also wondered if I should try one off a Explorer. This is a manual set up, MC on the firewall.

I'd use a good dual master cylinder with a 1" bore

My first, the rebuilt junk one, was 1 in bore, I think the one I got on it now is 15/16. It's one of those things where you say, "I'll remember this" and then 2 wks later you haven't got a clue.The pedal feels pretty good, so I'll give it a shot. Thanks

15/16 is even better, as long as it moves enough fluid.

I seem to remember that if the M/C you're using is supposed to go with drums in the rear you'll need to install a proportion valve to turn down the juice to the rear disc.
