1. A disc brake for a utility vehicle, comprising:
a stationary brake carrier;
a brake caliper which engages over a brake disc having a rotation axis, is formed as a sliding caliper, and is fastened to the stationary brake carrier;
two brake pads which are arranged in the brake caliper, are moveable in opposite axial directions and have, in each case, a pad carrier plate having opposite sides spaced apart in a direction orthogonal to the rotation axis and opposite faces spaced apart in the axial direction, and a friction lining fastened to one of the opposite faces, wherein
one brake pad is an action-side or application-side brake pad pressable via an application apparatus by way of at least one brake piston against the brake disc, wherein
the brake pads are received, in each case, in a pad channel of the stationary brake carrier, the pad channel being defined by two opposing brake carrier horns comprising inner facing surfaces opposing each other and a longitudinal connector that connects the two opposing brake carrier horns; and
a pad resetting apparatus assigned to at least one of the two brake pads and comprising at least one holding portion fastened by enclosing an outer contour of at least one of the two opposing brake carrier horns and a spring arm connected to the at least one holding portion and projecting obliquely from the inner facing surface of the at least one brake carrier horn, wherein the spring arm engages one of the sides of the pad carrier plate, and wherein the assigned one brake pad is returnable via the spring arm applying an axial return compression force to the assigned one brake pad in the direction of the rotation axis after a braking-induced displacement and release of the disc brake.
