FLUID PRESSURE INSPECTION & REPAIR

Inspect The Fluid Pressure

1. Set the rear axle load.

Rear axial load (include vehicle weight) :

6_series 1,200 kg

3. Raise the front brake pressure to 50 kg/ cm2 (711 psi) and check the rear brake pressure.

Rear brake pressure:

1. Brake pedal should not be depressed twice and/or returned while setting to the specified fluid pressure.

2. Read the value of the rear wheel cylinder pressure two seconds after adjusting the specified fluid pressure.

4. Raise the front brake pressure to 100 kg/ cm2 (1,422 psi) and check the rear brake pressure

Adjust The Fluid Pressure

1. Adjust the length of the No. 2 shackle.

Low pressure - Lengthen A

High pressure - Shorten A

FJ,BJ,HJ4_series except FJ40

120 mm (4.72 in.)

114 - 126 mm 4.49 - 4.96 in.)

One turn of the No. 2 shackle changes the fluid pressure about 0.6 kg/cm2 (8.5 psi).

2. In event pressure cannot be adjusted by the No. 2 shackle, raise or lower the position of the valve body.

Low pressure - Lower

High pressure - Raise

Tightening torque:

3. Adjust the length of the No. 2 shackle again.

Inspect The Load Sensing Valve

If it cannot be adjusted, inspect the valve housing in the following manner.

1. Assemble the valve body in the uppermost position.

When the brakes are applied, the piston will move down about 1 mm (0.04 in.). Even at this time, the piston should not contact or move the load sensing spring.

2. In this position, check the rear wheel cylinder pressure.

Front wheel

Rear wheel

5 ( 71) 10.4 - 14.4 (148 - 205) 21.9 - 28.9 (312 - 411)

If the measured value is not within standard, replace LSPV assembly.

INSPECTION

1. Inspect the valve piston pin and load sensing spring contact surfaces for wear. Wear:

Limit 0.7 mm

1. Assemble the following parts to the load sensing spring.

(1) Bushing

(2) Rubber plate

(3) Bushing

(4) Collar

(5) Load sensing valve boot

(6) Load sensing spring boot

Prius Axle Load Wheel Load

Set the LSPV body in the following procedure.

(1) Set the rear axle load.

(2) When pulling down the load sensing spring, confirm that the valve piston moves down smoothly.

(3) Position the valve body so that the valve piston lightly contacts load sensing spring

(4) Tighten the valve body mounting nuts

Tightening torque:

Install the LSPV gauge (SST) and bleed the air
