REMOVAL & INSTALLATION
- Remove the vacuum hose from the valve.
- Remove the valve from the bracket by removing the clip, if equipped, or rotating the valve back and forth and carefully lifting out of the bracket assembly.
- Install the valve to the bracket by pushing the valve in. Install the retaining clip if equipped.
- Connect the vacuum hose.
- Adjust the valve, as described.
See Figure 1
The vacuum dump valve is movable in its mounting bracket. It should be adjusted so that it is closed (no vacuum leak) when the brake pedal is in its normal released position (not depressed), and open when the pedal is depressed. Use a hand vacuum pump to make this adjustment.
