Tools Required:
The vacuum dump valve is adjustable in its mounting bracket. It should be
adjusted so that it is closed (no vacuum leak) when the brake pedal is in its
normal release position (not depressed), and open when the pedal is depressed.
Use Rotunda Vacuum Tester 021-00037 or equivalent to check dump valve operation.
