Load Compensator: Testing and Inspection

FLUID PRESSURE TEST
Before testing the LSPV, confirm that the fuel tank is filled with fuel and the vehicle is equipped with its spare tire, tools, jack and jack handle.
1. Place vehicle on level floor and set 100 kg (221 lbs.) weight slowly on axle housing center.





2. Install special tool to front and rear brake.

NOTE: Special tool No. 09956-02310 should be connected to breather of front (left side brake) and rear brakes.





3. Depress brake pedal gradually until fluid pressure of the front brake becomes as specified below and check corresponding pressure of rear brake then. It should be within the specification given.





^ As done above, apply 100 kg/cm2 pressure to front brake and check that rear brake pressure then is within the specifications given.





4. If the rear brake pressure is not within specification, adjust it by changing bolt "A" tightening position as follows.
^ If rear brake pressure is higher than specifications, move bolt "A" upward and if it is lower, downward.
^ Repeat steps 3 and 4 until rear brake pressure is within specifications.

NOTE: 1 mm of bolt movement will result in about 2.4 kg/cm2 difference in hydraulic pressure.

^ After adjustment, be sure to torque nut (a) to 23 Nm (17.0 ft. lbs.)








5. Disconnect brake pipe (connecting between master cylinder and right front brake) from master cylinder. Tighten plug with special tool No. 09956-02210. Depress brake pedal. If rear brake pressure is 95 - 100 kg/cm2 when front brake pressure is 100 kg/cm2, it means that the front fail-safe system functions properly.
6. Upon completion of the fluid pressure test, bleed the brake system and perform the brake test.
