Abstract: A sliding caliper disc brake for a motor vehicle having a disc, a carrier (2), a caliper (3) and pads (52). The carrier (2), respectively, provides bearing surfaces (61b, 63b) for the caliper (3) and pads (52) having a non-zero angle (Ab) which opposes rotational movement between the caliper (3) and pads (52) when the disc turns in a direct sense (D). Thus, a resistance to a braking torque generated during braking is dampened by a shear force developed between the caliper (3) and pads (52).
