Notes On Evaluating Brake Disks - AH42.10-P-9406-07RQ

Model 167, 190, 197, 205, 206, 212, 213, 217, 218, 222, 223, 231, 232, 253, 290, 295, 297 with code B07 (AMG - ceramic brake system) 

The ceramic brake disk cannot be visually inspected for wear.

A wear test can only be performed using the electronic measurement method (e.g. Proceq) or by evaluating the wear indicators using the test films.

The smaller chippings shown are normal, they have no influence on brake power or durability and are therefore not a problem.
