Checking

1.1

Check lining thickness of brake pads in the brake caliper

Only on disk brake on front axle

 Check the outer brake pads through the top wheel wrench opening (arrow). To illuminate the visual field hold a hand lamp or flashlight at the wheel wrench opening. Check the inner brake pads from the vehicle underside.

 If the brake lining thickness of the brake pad is approaching the brake lining wear limit, all brake pads must be checked by removing the wheels. This indirect check is only a rough check due to tolerance dimensions and obstructed vision.

For safety reasons a direct check of the brake lining thickness by removing the wheels is necessary

- subject to separate repair order.
