A residual pressure valve is used when a master cylinder is mounted equal to or below
the horizontal plane of the calipers or drum brake wheel cylinders. This valve prevents
fluid flow-back to the master cylinder reservoir which can cause excessive brake travel
or “pumping” of the pedal to engage brakes.
Install the valve as close as possible to the master cylinder and position the end marked
“M.C.” toward the master cylinder and the end marked “OUT” toward the brakes. Ports
in the valve are 1/8-27 NPT threads and will accept standard inverted flare tube
nut adapters.
A 2 lb. valve is designed for disc brakes and a 10 lb. valve for drum brakes. If the vehicle
has a single outlet master cylinder and a disc/disc system, only one 2 lb. valve is
required. If the vehicle has a single outlet master cylinder and a disc/drum system, a 2
lb. valve is required in the disc brake line and a 10 lb. valve in the drum brake line (after
the tee fitting). Balance bar systems require the appropriate valve just outside the
master cylinder.
