Checking brake pad thickness (shown as an example)

• If brake pad wear is indicated by the warning light, the warning contact line must also be replaced. 
• Replacement of the warning contact can be avoided by replacing the brake pads before a pad thickness -Arrows- of 2.5 mm is reached. 
• Warning contacts must be replaced if the core of the wire is worn. 
• If only the plastic part of the warning contact is worn, the warning contacts need not be replaced. 

1. Carefully pull off warning contact -1-  on the brake pad -2-  and then disconnect the cable plug -3-  at the plug connection.
