Without Antilock Brakes

CAUTION: Proportioning valves should never be disassembled.

There are two proportioning valves per vehicle. One is for the right rear brake, while the other is for the left rear brake. This procedure can be used for either, although it applies to the removal and installation of only one valve.

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.

Non-ABS Proportioning Valve Locations On Master Cylinder:

2. Disconnect the brake tube from the proportioning valve requiring removal.
3. Unscrew and remove the proportioning valve from the master cylinder.

INSTALLATION
1. Wet the O-ring seal on the proportioning valve using clean fresh brake fluid.
2. Install the proportioning valve in the master cylinder and hand tighten it until the proportioning valve and its O-ring seal is fully seated in the master cylinder. Torque the proportioning valve to 40 Nm (30 ft. lbs.).
3. Install the brake tube on the proportioning valve. Tighten the tube nut to a torque of 17 Nm (145 in lbs.).
4. Remove the brake pedal holding tool.
5. Bleed the affected brake line. See Brake Bleeding.
