1. A motor vehicle disc brake lining assembly which can be mounted in a holder so as to be rotationally fixed and axially displaceable relative to a theoretical wheel rotational axis, comprising:
friction material which is fixed on the front side of a back plate; and
a friction lining resetting spring which is fixed on the rear side of the back plate,
wherein the friction lining resetting spring has a base and a connected resetting spring bow which is bent into a spatial curve and incorporates elasticity such that the resetting spring bow is suitable and intended for sitting elastically pretensioned on an abutment of the holder in braking operation, such that the motor vehicle disc brake lining can be reset under the resetting spring force or spring preload in the axial direction out of a brake actuation position; the friction lining resetting spring has a spring characteristic force-travel curve which is additively composed of a plurality of portions comprising a plurality of straight portions A, C, D and at least one curved transition portion B between the straight portions A and C, the portions A, C, D comprising respective mutually differently defined gradient angles α, γ, δ, wherein the at least one curved transition portion B is degressively curved,
wherein, the friction lining resetting spring is designed at least partially plastically deformable and which, serves to automatically allow demand-oriented spring resetting on the basis of wear compensation.
