[35A] BASIC BRAKE SYSTEM - - ON-VEHICLE SERVICE - PROPORTIONING VALVE FUNCTION TEST <VEHICLES WITHOUT ABS> | PRINT PAGE / INDEX / PRIOR / NEXT

| PROPORTIONING VALVE FUNCTION TEST <VEHICLES WITHOUT ABS> CAUTION The proportioning valves are installed independently for the right and left brake lines. Always measure each valve.
| Connect two pressure gauges to the output port of the master cylinder and output port of the proportioning valve. Bleed the brake line and the pressure gauges (Refer to ).
| Depress the brake pedal gradually. Then check that the split point, where the output fluid pressure begins to drop in proportion to the output fluid pressure, is at the standard value. Standard value: 3.19 - 3.67 MPa Depress the brake pedal more strongly than at the above step. Then check that the output fluid pressure is at the standard value when the input fluid pressure is 7.35 MPa. Standard value: 4.17 - 4.66 MPa Measure each output fluid pressure at both valves, and check that the difference between the two is at the limit value or less. Limit: 0.5 MPa If the measured pressure exceeds the limit, replace the proportioning valve.
