Hook up proportioning valve

The proportioning valve modulates the pressure to the rear brakes the modulation is necessary to minimize rear wheel lock up found in heavy braking and to compensate for the differences in braking conditions in front disc / rear drum systems. Proportioning valves do not function like normal valves, as they limit, but do not totally shut off pressure to the rears fixed (factory production) pvs allow full master cylinder pressure to the rears up to a pre-determined split or knee value, then reduce increasing rear pressure to a percentage , typically 27, 43, or 59% of master. Why you might need a brake proportioning valve a big brake upgrade will give your front brakes more leverage (larger diameter disk = more leverage) so when you hit the brake pedal the front brakes will lock up much earlier than the rears. The proportioning valve is mounted between the brake line master cylinder and the rear wheels it's designed to adjust the pressure between the front and rear brakes, depending on how hard you're stopping. Mopars are known to have overly sensitive rear brake lock-up issues in a panic or hard stop proportioning valves are a band-aid for poorly matched brake components.
