Brake Load Sensor Proportioning Valve Adjustment
WARNING:
Adjust the brake load sensor proportioning valve with the vehicle at correct ride height. Incorrect adjustment may result in degraded braking performance. Failure to follow this instruction may result in serious personal injury.
NOTE:
The vehicle should be in an unladen condition.
NOTE:
The brake load sensor proportioning valve adjustment should be carried out with the vehicle weight resting on the wheels and tires.
- Using additional weight, set the vehicle to the correct ride height. Refer to the chart below.
Fuel Tank Level Additional Weight Required kg lb Empty 40 88 1/4 Full 30 66 1/2 Full 20 44 3/4 Full 10 22 - Loosen the fasteners.
- Loosen the proportioning valve lever nut.
- Loosen the valve spring setting bar screw.
- Set the proportioning valve lever position.
- Position the proportioning valve lever on the stabilizer bar so that the valve spring setting bar is central in relation to the setting bar screw.
- Tighten the nut to 28 Nm (21 lb-ft).
- Measure the dimension between the lower end of the proportioning valve spring hook and the groove on the valve spring setting bar. Adjust the proportioning valve spring setting bar to the correct position.
- Tighten the proportioning valve spring setting bar screw to 12 Nm (9 lb-ft).
- Remove the additional weight, if necessary.
WARNING:
Before adjusting the brake load sensor proportioning valve, the additional weight must be positioned centrally over the rear axle. Adding weight in an incorrect location may result in an incorrect adjustment of the brake load sensor proportioning valve and degraded braking performance. Failure to follow this instruction may result in serious injury to vehicle occupant(s).
CAUTION:
While tightening the proportioning valve spring setting bar screw, make sure that the setting bar does not move.
