Checking Parking Brake [EA9]

Checking Parking Brake





If the parking brake is sticking or badly adjusted, it may lock one or both rear wheels when driving. This means there will be no wheel sensor signals, so DTCs may be posted.

Check that parking brake lever, leads and brake drums are not sticking anywhere. Check that brake drums and brake leads are properly adjusted.

If parking brake is OK:
- Check outlet valves EA10. Checking Outer Valves [EA10]

If parking brake is not OK:
- Adjust as necessary.
