Brake experts please
Aftermarket out of the question down here $$$
Was going to use std 2 pot front calipers on rear as have J55 setup for front.No need for handbrake.
(Std 12" fr and rear discs same thickness , just offset different which is not a issue as I have to fab custom caliper brackets)
Question
Will I have to upgrade the Master cylinder to have
4 x 2 pot calipers instead of stock 2x2 pots and 2 singles?
What size?
Thanks in advance.
