Abstract
A motor vehicle disc brake lining having friction material fixed on the front side of a back plate, and a resetting spring fixed releasably or non-releasably on the rear side of the back plate with a base and an elastic resetting spring bow. The resetting spring bow sits elastically on an assigned abutment of a holder such that the motor vehicle disc brake lining can be reset to be axially distanced from a brake disc in the released brake state. The friction lining resetting spring has a spring characteristic curve which is additively composed of a plurality of portions including a plurality of quasi-linear straight portions and, interposed in-between, at least one curved transition portion, each having mutually differently defined gradient angles, and among the portions there is at least one portion which is at least partially plastically deformable and serves to automatically allow demand-oriented spring-back based on wear compensation.
