Claim 6:
7. A disc brake for commercial vehicles, comprising:
a brake disc (13);
a first brake lining (14) on a first side of the brake disc (13);
a second brake lining (16) on a second side of the brake disc (13) opposite the first side;
a brake carrier (10);
a brake caliper (12) mounted in a floating manner;
a spreading device (28, 30; 42, 44; 48, 50), wherein the spreading device (28, 30;
42, 44; 48, 50) is configured to generate a force to move the first brake lining (14) and the second brake lining (16) away from one another, wherein the spreading device (28, 30;
42, 44; 48, 50) includes two elastic elements, both of which are retained on a common retainer bracket (18) extending across the first and the second brake lining (14, 16); and
a restoring device (52), wherein the restoring device (52) is configured to generate a force to move the brake caliper (12) in relation to the brake carrier (10) in the direction opposite to a direction of movement of the brake caliper (12);
wherein the retainer bracket (18) extends axially across the first and the second brake lining (14, 16)i
wherein the brake caliper (12) is mounted on a bolt (54) displaceably in relation to the brake carrier (10), and the restoring device (52) includes a spring arranged entirely inside the bolt;
wherein the restoring device (52) has a compression spring (58), the compression spring (58) being supported on a first stop (60) on a side facing the brake disc, wherein the first stop (60) is coupled axially to the brake caliper (12) at least in terms of a movement toward the brake disc (13), and
the compression spring (58) being supported on a second stop (64) on a side facing away from the brake disc, wherein the second stop (64) is coupled axially to the bolt (54) at least in terms of a movement away from the brake disc (13).
