Abstract
In a brake jaw consisting of a lining support member (2) and a friction lining (4), an intermediate layer (6, 8) arranged between the friction lining (4) and the lining support member (2) and acting as a damping layer to avoid squealing caused by friction, it is provided that the intermediate layer (6, 8) consists of a material mixture that is adapted to damp friction squealing during braking and to generate an acoustic alarm signal when reaching the wear limit.
