FRICTION LINING HOLDING SPRING FOR IMPROVED BRAKE PISTON FIXING
A friction lining holding spring and the equipped component/assembly, specifically a motor vehicle disc brake lining, including the friction lining holding spring. The friction lining holding spring includes an offset knee piece of a U-spring leg, which branches off at an angle from a largely flat U base section, and wherein the largely flat base section has a fastening tab with a cup-shaped rim hole including a through-opening for the purpose of fixing on a backplate of the friction lining, wherein each knee piece has integrated gearing, which is in particular designed as an uneven brake piston insertion trajectory such that, when a brake piston is inserted, there is a predefined gearing reduction effect for the purpose of automatically influencing or modelling the necessary force requirement.
