Information on measuring thickness of outer brake pads:

To avoid measurement errors, before starting each measurement the slide (2) must contact the driver (3).

The test mandrel (4) must be inserted in the check bore of the lining carrier (5) so that the test mandrel (4) contacts the brake disk.

Fit the brake pad gauge (1) to the lining carrier (5).

Remove brake pad-gauge (1) and read off measured value on the slide valve (2).
