Load Compensator: Testing and Inspection

CAUTION:
- Carefully monitor brake fluid level at master cylinder.
- Use new brake fluid "DOT 3".
- Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed on paint areas, wash it away with water immediately.
- Depress pedal slowly when raising front brake pressure.
- Check rear brake pressure 2 seconds after front brake pressure reaches specified value.
- For models with ABS disconnect harness connectors from ABS actuator relay before checking.

1. Ensure vehicle is unladen condition (i.e. fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.)
2. Have a driver sit in the driver's seat and one person sit on the rear end. Then have the person on the rear end slowly get off the vehicle. This is necessary to stabilize suspension deflection.





3. Gradually depress brake pedal and attach a lever to the stopper bolt, then adjust length "L" as follows:
Length "L": approximately 194 mm (7.64 inch)
4. Remove front LH tire.





5. Connect tool to air bleeders on front LH brake caliper and rear LH or RH brake wheel cylinder.
6. Install front LH tire.

CAUTION: Before installing front LH tire, confirm the tool is not touching the front LH wheel.





7. Bleed air from Tool.





8. Raise front brake pressure to 4,904 kPa (711 psi) and 9,807 kPa (1,422 psi) and check rear brake pressure.








9. 9. Set down weight slowly over axle center so that sensor spring length becomes the same as when in loaded condition (Refer to the illustration). Check rear brake pressure in the same way described in step 6.
10. Bleed air after disconnecting the tool. Refer to Brake Fluid / Service and Repair / Bleeding Brake Fluid.
11. Install front LH tire.
