Testing Brake Servo Diaphragm
1. Remove the vacuum supply line from the brake servo fitting.
2. Attach the vacuum tester to the vacuum supply port on servo (figure 13).
3. Create approximately 15 inHG by operating the pump.
4. Wait 30 seconds.
5. Check the gauge reading – there should be no vacuum drop observed.
If the vacuum drops this indicates the brake servo diaphragm is faulty. If faulty the servo
should be removed by an authorised repairer or replaced.
