Brake Proportioning/Combination Valve: Testing and Inspection
FUNCTION TEST
1. Connect two pressure gauges, one input side and one to the output side of the proportioning valve.
NOTE: Be sure to bleed the system after you connect the pressure gauge.
2. With the brakes applied, measure the input pressure and the output pressure. If the measured pressures are within the ranges as illustrated, the
proportioning valve is good.
3. Reconnect the brake lines in their original positions and bleed the system.
NOTE: This figure shows characteristic of the proportioning valve during pressure increase.
