PAD WEAR MEASURING DEVICE FOR A BRAKE, IN PARTICULAR DISC BRAKE, BRAKE, AND BRAKE PAD SET

摘要

The invention relates to a pad wear measuring device (6, 6') for a brake, in particular disc brake (1), comprising at least one brake pad (3, 3') with a pad backplate (3a, 3'a), to which there is applied a friction mass (3b, 3'b), and an evaluation unit (11). The evaluation unit (11) of the pad wear measuring device (6, 6') comprises a first measuring unit (11a), wherein the first measuring unit (11a) cooperates with the friction mass (3b, 3'b) of the at least one brake pad (3, 3') and indirectly detects the pad thickness (h) of the friction mass (3b, 3'b) of the at least one brake pad (3, 3'). A brake and a brake pad set are also provided.
