ON−VEHICLE INSPECTION
1. SET REAR AXLE LOAD
Rear axle load (include vehicle weight):
1,330 kg (2,932 lb)
2. INSTALL LSPV GAUGE (SST) AND BLEED AIR SST 09709−29018
3. RAISE FRONT BRAKE PRESSURE TO 7,845 kPa (80 kgf/cm
2, 1,138 psi) AND CHECK REAR BRAKE PRES-
SURE
Rear brake pressure:
5,984 ± 589 kPa (61 ± 6 kgf/cm
2, 869± 86 psi)
HINT:
The brake pedal should not be depressed twice and/or returned
while setting to the specified pressure. Read the value of rear
pressure 2 seconds a fter adjusting the specified fluid pressure.
4. IF NECESSARY, ADJUST FLUID PRESSURE
(a) Disconnect the No.2 shackle from the shackle bracket.
(b) Adjust the length of the No.2 shackle turning it. Low pressure − Lengthen A.
High pressure − Shorten A
Initial set: 90 mm (3.54 in.)
Adjusting range: 84 − 96 mm (3.31 − 3.78 in.)
HINT:
One turn of the No.2 shackle changes the fluid pressure by
about 98.1 kPa (1.0 kgf/cm
2, 14.2 psi).
(c) In event the pressure cannot be adjusted by No.2 shackle, raise or lower the valve body.
Low pressure − Lower
High pressure − Raise
(d) Torque the 2 nuts. Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
(e) Adjust the length of the No.2 shackle again.
If it cannot be adjusted, inspect the valve housing.
