Removal - Proportioning Valve (Height Sensing)

REMOVAL - PROPORTIONING VALVE (HEIGHT SENSING)

1. Using a brake pedal depressor, move and lock the brake pedal to a position past its first 1 inch of travel. This will prevent brake fluid from draining out of the master cylinder when the brake tubes are removed from the proportioning valve.
2. Raise vehicle.

CAUTION: Before removing the brake tubes from the proportioning valve, the proportioning valve and the brake tubes must be thoroughly cleaned. This is required to prevent contamination from entering the proportioning valve or the brake tubes.

3. Remove the four brake tubes from the inlet and outlet ports of the proportioning valve (Figure 1).

4. Remove the two bolts attaching the proportioning valve and bracket to the vehicle (Figure 1).
5. Slide the bracket out from under rear track bar bracket. Lower the valve down enough to pull its actuator rod out of the axle bracket and remove the proportioning valve from the vehicle.
