Fluid Pressure Test

FLUID PRESSURE TEST (if equipped with LSPV)





Test procedure for LSPV assembly is as follows.
Before testing, confirm the following.
^ Fuel tank is filled with fuel fully.
^ Vehicle is equipped with spare tire, tools, jack and jack handle.
1. Stop vehicle on level floor and place approximately about 200 kg (441 lbs.) weight on rear housing so that rear axle weighs 800 kg (1764 lbs.).
Rear axle weight "L": 800 kg (1764 lbs.)
2. Install special tool to front and rear brake.

NOTE: Special tool should be connected to breather of front (driver's side brake) and rear brakes.

Special Tool
Front brake
(A): 09956-02310
(B): 09952-46510 (Attachment for vehicle with H25 engine)
(C): 55473-82030 (Air bleeder plug supplied as a spare part)
Rear brake
(A): 09956-02310
(B): 09952-36310
(C): 55473-82030 (Air bleeder plug supplied as a spare part)

NOTE: Special tool (B) is used instead of thread diameter 10 mm attachment of special tool (A). So remove the attachment from (A) and install (B) as shown in figure.

For vehicle with other than H25 engine, use the attachment included in special tool (A).








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





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





4. If rear brake pressure is not within specification, adjust it by changing stay "A" position as follows.
Tightening Torque (a): 23 Nm (2.3 kg.m, 17.0 ft. lbs.)
^ If rear brake pressure is higher than specification, move stay "A" to direction "a" and if it is lower, to direction "b".
^ Repeat steps 3) and 4) until rear brake pressure is within specification.
^ After adjustment, be sure to torque bolt to specification.








5. Disconnect brake pipe (connecting between master cylinder secondary side and 4-way joint) from master cylinder.
Tighten plug (special tool) to master cylinder.
Depress brake pedal. If rear brake pressure is 95 - 100 kg/cm2 when front brake pressure is 100 kg/cm2, it means that front fail safe system functions properly.
Special Tool (A): 09956-02210
6. Upon completion of fluid pressure test, bleed brake system and perform brake test.
