Hydraulic Assembly: Testing and Inspection


NOTE:
- The roller of the braking force tester and the tire should be dry during testing.
- When testing the front brakes, apply the parking brake, and when testing the rear brakes, stop the front wheels by chocking them.

1. Jack up the vehicle and support the vehicle with rigid racks placed at the specified jack-up points or place the wheels which are checked on the rollers of the braking force tester.
2. Release the parking brake, and feel the drag force (drag torque) on each road wheel. When using the braking force tester, take a reading of the brake drag force.
3. Turn the ignition key to the "OFF" position and set the scan tool as shown in the diagram.
4. After checking that the selector lever is in neutral, start the engine.

NOTE:
- At this time, the ABS system will switch to the scan tool mode and the ABS warning light will illuminate.
- When the ABS has been interrupted by the fail-safe function, the scan tool actuator testing cannot be used.

5. Use the scan tool to force-drive the actuator.
6. Turn the wheel by hand and check the change in braking force when the brake pedal is depressed. Use a braking force tester to check the braking force. When the actuator is force-driven with the brake pedal depressed the braking force must change. The results should be as shown.
Front wheel force 785 - 981 N (176 - 220 lbs.)
Rear wheel force 588 - 785 N (132 - 176 lbs.)







NOTE: The result should be as shown in the diagram.






7. If the result of inspection is abnormal, correct according to the diagnostic table.

NOTE: Connection and disconnection of the scan tool should always be made with the ignition switch in the "OFF" position.

8. After inspection, disconnect the scan tool immediately after turning the ignition "OFF."
