yeh i think that will bethe way to go

i have just installed a r31 skyline diff and disc brakes into my 1200 ute.
i have a 180b master cylinder and the booster is from a BMW323.
the front disc brakes are working fine and the rear are not clamping the disc fully.( the pedel is like a sponge but lines are not leaking)
does anyone know if there a valve in the master cylinder that needs to be removed to allow for disc brakes on the rear? or any other ideas?
thanks
