21mm Dual Master Brake Circuit Kit – ’55-’70 Split/Bay Window Bus
This kit installs a dual circuit master cylinder into your 55-70 vw bus
A must for a disk brake conversion!
We use 2 style master cylinders, 1971-79 bus with 24mm pistons or a rabbit master cylinder with 21mm pistons.
We like to use the late bus master cylinder for disk brakes with LARGE piston calipers and we use the rabbit for small piston disk brakes (1.5 inch &under) or drum brakes.
