Proportioning Valve Test Fitting Installation
Proportioning Valve Test Fitting Installation
3. Install the required fittings from Pressure Test Fittings, Special Tool 6833, or equivalent into the inlet port of the proportioning valve assembly,
from which the chassis brake line was removed. Install the removed chassis brake line into the Pressure Test Fitting. Install the required fitting
from Pressure Test Fittings, Special Tool 6833, or equivalent into the required outlet port of the proportioning valve. Install the required fitting
from Pressure Test Fittings, Special Tool 6833, or equivalent into the required outlet port of the proportioning valve. Then install the removed
chassis brake line into the Pressure Test Fitting.
Pressure Gauges Installed On Pressure Test Fittings
4. Install a pressure gauge from Gauge Set, Special Tool C-4007-A, or equivalent into each pressure test fitting. Bleed air out of hose from pressure
test fittings to pressure gauges, at the pressure gauges. Then bleed air out of the brake line being tested, at that rear wheel cylinder.
5. With the aid of a helper, apply pressure to the brake pedal until a pressure of 6895 kPa (1000 psi) is obtained on the proportioning valve inlet
gauge. Then based on the type of brake system the vehicle is equipped with and the pressure specification shown on the following table, compare
the pressure reading on the outlet gauge to the specification. If outlet pressure at the proportioning valve is not within specification when required
inlet pressure is obtained, replace the proportioning valve.
6. Remove the pressure test fittings and pressure gauges from the proportioning valve.
