IMPORTANT:

The brake pad wear sensor must be replaced once it has been removed (brake pad wear sensor loses its retention capability in the brake pad).

Necessary preliminary tasks:

Remove wheel. See 36 10 300 REMOVING OR INSTALLING FRONT OR REAR WHEEL .
Remove brake pad wear sensor. See Replacing a Brake Pad Sensor (Front)
Read and comply with General Information. See General Information

Press clutch pedal down to floor and secure with pedal support.

NOTE: The pedal support may only be released when the brake lines are reconnected. This prevents brake fluid from emerging from the expansion tank and air from entering the system when the brake lines are opened.
