8. The disc brake according to claim 7 , wherein

the entry-side carrier lug is higher than a point of intersection of the force action line F Rxges with the entry-side carrier lug.

9. The disc brake according to claim 8 , wherein

a support surface of the lining carrier plate adjacent to the entry-side carrier lug of the brake carrier has an offset configured to engage into an undercut on the entry-side carrier lug.

10. The disc brake according to claim 9 , wherein

the entry-side carrier lug of the brake carrier and the support surface of the lining carrier plate adjacent to the entry-side carrier lug are configured to engage into one another in a positively locking manner.

11. The disc brake according to claim 1 , wherein

an arc angle covered by the friction lining in a circumferential direction of the brake disc when the brake lining is on the brake carrier is greater than 25°.

12. The disk brake according to claim 11 , wherein

the arc angle is greater than 30°.

13. A brake lining for a disc brake, comprising

a lining carrier plate; and having fastened thereto

a friction lining on the lining carrier plate,

wherein

the lining carrier plate has lateral support surfaces for support against entry-side and exit-side inner walls of carrier lugs of a brake carrier of the disk brake,

at least one of the lateral support surfaces of the lining carrier plate has an offset for positively locking into one of the side inner walls of the carrier lugs, and

the lining carrier plate has an exit-side support contour for abutment against the exit-side inner wall of the brake carrier, and

an exit-side abutment contour of the lining carrier plate has an opposing exit-side support surface configured to oppose an opposing exist-side support surface of the exit-side carrier lug, the opposing exit-side support surfaces being inclined by an angle of inclination α with respect to a Y axis of the disc brake in at least one of regions of the opposing exit-side support surfaces and at least at a radially highest point of the lining support on the brake carrier, the Y axis being an axis of a coordinate system in which the axis of rotation of the brake disc is the Z axis, the Y axis extends perpendicular to the axis of rotation of the brake disc through a center of the brake lining when located on the brake carrier and the X axis is perpendicular to the Z axis and the Y axis, and

the exit-side support surface of the lining carrier plate and the entry-side support surface are configured such that the lining carrier plate is removable from the brake carrier by pivoting the exit side of the brake lining away from the brake carrier in a direction radially away from the axis of rotation of the brake disc.
