I installed a so called "P30" master cylinder on my coach. In order for the lines to hook-up I had to switch the front brake line to the secondary bore and the rear brakes to the primary piston in the master cylinder. This means the pressure in the rear brakes applies the front brakes. Did GM have a reason for engineering it so the pressure in the front brakes drives the piston for the rear brakes? I know the combination valve holds off delivery of pressure to the front brakes until the pressure is 300-400 psi. Any Hydraulic engineers out there?
