REMOVAL & INSTALLATION
See Figure 1
- Disconnectr the brake lines from the valve body.
- Remove the locknut and disconnect the spring from the lower control arm.
- Remove the 2 mounting bolts and extract the LSP and BV assembly.
- Attach the valve assembly to the vehicle and tighten the bolts to 14 ft. lbs. (19 Nm).
- Positon the spring on the lower control arm and set the length with the adjusting nut. The initial set length should be 1.18 inch (30mm). Tighten the assembly to 9 ft. lbs. (13 Nm).
- Connect the brake lines and secure each one to 11 ft. lbs. (15 Nm).
- Fill the brake master cylinder with fresh brake fluid, then bleed the brake system.
- Check and adjust the fluid pressure.
- Test driver the vehicle.
FLUID PRESSURE ADJUSTMENT
See Figures 2 through 10
- Set the vehicle unladen.
- Measure the rear axle load and note the value.
- Set the rear axle load. Standard load is 2028 lbs. (920 kg).
- Install a Load Sensing Proportioning gauge (SST 09709-29017) and bleed the air from the system.
- Raise the front brake pressure to the following specifications and check the pressure of the rear brakes.
The brake pedal should not be depressed twice and returned while setting to the specified pressure.
- Read the value of the rear pressure 2 seconds after adjusting the specified fluid pressure.
If necessary, adjust the fluid pressure:
Adjust the spring shaft length by turning the adjusting nut.
Low pressure-lengthen A
For every turn of the adjuster, the fluid pressure with change by about:
Rear drum-28.4 psi (196.1 kPa)
- Tightrn the nut to 9 ft. lbs. (13 Nm).
- Adjust the spring shaft length by turning the adjusting nut.
- Remove the gauge and bleed the brake system.
- Check for leaks and test drive the vehicle.
