8. Attach a Gauge (1), Special Tool C-4007-A, to each pressure adapter.
9. Remove the brake pedal holding tool.
10. Bleed any air out of the pressure gauge hoses at the pressure gauge. See: Brake Bleeding
11. With the aid of a helper, apply pressure to the brake pedal until the reading on the proportioning valve inlet gauge is at the target inlet pressure
shown in the Brake Proportioning Valve Applications And Pressure Specifications table at the end of this procedure. If the inlet gauge
pressure overshoots its target pressure when the pedal is depressed, release the brake pedal, relieving the pressure in the system, before reapplying
the pedal to reach the target pressure at the inlet gauge. This is necessary to get an accurate reading of the outlet pressure.
12. Once inlet pressure has been achieved, check the pressure reading on the proportioning valve outlet gauge. If the proportioning valve outlet
pressure does not agree with value shown in the table, replace the proportioning valve. If proportioning valve is within pressure specifications, the
valve is good and does not require replacement.
13. Reinstall the brake holding tool on the brake pedal.
14. Remove the testing tools from the vehicle and proportioning valve.
