What Master Cylinder for 4 wheel disk brakes?

This is what I just installed. 1 1/8 bore. 11” willwood in the front and ford explorer in the back. What a big difference in stopping it made. Much better feel and response. McKellar's Modified Rides
Call this guy up he help me tremendously when I was at the MATSLV. You will have to get the adapter to go from 4 bolt to 2 bolt.
This picture is not correct but close. It was $70.00 I think for it.

Thru years of testing, comparing, and replacing, - unless you have a power booster, that M/C would be terrible compared to 15/16 or smaller, in effort, feel, and modulation for a spirited driver.
