Vacuum Dump Valve
- Disconnect dump valve vacuum hose at servo, connect hand vacuum pump to hose and apply vacuum.
- If vacuum will not hold hose or dump valve leaks, components should be replaced or adjusted. Step on brake pedal. If vacuum is not released, adjust or replace dump valve.
NOTE:
DO NOT use a test light to test clutch switch. Use a voltmeter with 5000 volt/ohm rating or higher.
