With Antilock Brakes

CAUTION: Proportioning valves should never be disassembled.

NOTE: This procedure is for removal and installation of one of the two proportioning valves. It may be used for either one.

REMOVAL

Brake Pedal Holding Tool:

1. Using a brake pedal holding tool as shown, depress the brake pedal past its first one inch of travel and hold it in this position. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid to drain out of the master cylinder reservoir.
2. Raise the vehicle.

Antilock Proportioning Valve (Left Side Shown):

3. Remove the chassis brake tube nuts from the proportioning valve controlling the rear wheel of the vehicle which has premature wheel skid.
4. Remove the proportioning valve from the chassis brake tubes.

INSTALLATION
1. Install the proportioning valve in the chassis brake tubes. Tighten the 2 chassis brake tube nuts to a torque of 17 Nm (145 inch lbs.) torque.
2. Lower the vehicle.
3. Remove the brake pedal holding tool.
4. Bleed the affected brake line. See Brake Bleeding.
