The invention relates to a disc brake (1) for a motor vehicle, comprising a guide in which at least one brake pad assembly (10) is guided such that it can move in a braking manner, wherein the brake pad assembly (10) has a brake pad carrier (11) on which a vehicle brake pad (13) is attached which can be interacted with a brake disc in order to achieve a braking effect, wherein the brake pad carrier (11) has at least one retaining tongue (12), wherein the guide has at least one receiving region (32) and wherein the retaining tongue (12) can be accommodated in the at least one receiving means (32) by being guided in an actuation direction (B), wherein a reset device is in contact with the at least one retaining tongue (12), via which reset device a reset force acting against the actuation direction (B) can be applied to same subsequent to an elastic deformation caused by braking deflection of the brake pad assembly (10), wherein the reset device has an elastically deformable region (33, 133, 233, 333) for resetting the brake pad carrier (11) and a plastically deformable region (37, 137, 237) for the permanent adaptation to a wearing of the vehicle brake pad (13). According to the invention, with this disc brake (1), the reset device can only be plastically deformed, as a result of a force acting thereon in the actuation direction (B) along a guide surface (F) of the receiving region (32), if the reset device has adopted a predetermined, exclusively elastic deformation as a result of this force, wherein the plastically deformable region (37, 137, 237, 337) is formed as a loop and is in direct contact with the retaining tongue (12), and can also roll out along the guide surface (F) during the plastic deformation. |
