1. A disk brake for a utility vehicle, comprising:
a brake disc;
a brake caliper configured as a sliding caliper and to straddle the brake disk;
two brake linings arranged on opposite sides of the brake disc, each brake lining having a lining carrier plate and a friction lining on the lining carrier plate;
a brake carrier having brake carrier horns configured to abut respective sides of the two brake linings in a circumferential direction relative to a rotation axis of the brake disc;
a lining retaining bracket configured to be held on the brake caliper and span an assembly opening of the brake caliper;
a lining retaining spring on each of the two brake linings configured to cooperate with the lining retaining bracket to inhibit movement of the two brake linings away from the brake disc rotation axis; and
a resetting device having sprung spreading elements configured to bias the two brake linings away from one another and reset the two brake linings away from the brake disc after a displacement of the two brake pads toward the brake disc during a braking event,
wherein
the sprung spreading elements include two V-shaped spreading elements having spring legs which are supported on or fastened to the lining retaining bracket,
the spring legs of each of the two V-shaped spreading elements cooperate with both of the two brake linings such that the two brake linings are biased away from one another, and
each of the two V-shaped spreading elements includes a connecting region at a vertex of their V-shapes, wherein each of the connecting regions defines a longitudinal axis through the vertex, wherein the longitudinal axes are parallel and spaced apart in a direction parallel to the rotation axis of the brake disc, and wherein the two V-shaped spreading elements do not intersect each other.
