2017 Mercedes AMG c43 4 MATIC EPB procedure

Decelrometer unsuitable to test the EPB

To test the EPB:

Vehicle in the rollers
Leave the engine running as switching engine /ignition off will automatically place the gearbox in PARK

Ensure the gearbox is in neutral
Start the rollers together or signally and apply the EPB switch ,one pull is suffice to gain the required efforts .

The service brake can be tested in the rollers the normal way ( leave the engine running )

If your not 100 happy /unsure to test the service brake in the rbt ,use the rbt for the parking brake and decelrometer for the service brake .
