Examination
Stop valve leak test
Check with a manual vacuum pump.
When connected from the amplifier side (1):
- The vacuum reduction should be in the order of 1.3 kPa (10 mmHg) within 15 seconds at -66.7 kPa vacuum (-500 mmHg)
- When connected on the motor side (2): There should be no vacuum.
Installation
The check valve must be installed in the required direction. Follow the marking or label.
Attention:
Insert the vacuum hose to a depth of more than 24 mm.
If the hose is connected incorrectly, the normal operation of the brake booster will be impaired.
Do not use lubricants during assembly.
