Abstract

A disc brake has a brake disc and brake pads each having a pad back plate and mounted on opposite sides of the brake disc. A brake caliper engages over brake disc and brake pads. A pad hold-down device secures the brake pads and bears against pad back plates of the brake pads transversely to the brake pads. A flat spring bears against a side of the pad hold-down device facing away from the brake pads. The flat spring extends in longitudinal direction of the pad hold-down device. First and second spring abutments support first and second spring ends of the flat spring. The first spring abutment has a fastener extending transversely to pad hold-down device and to flat spring. The first spring abutment has a clip connected to the brake caliper by the fastener. The first spring end bears against an inner side of the clip facing the fastener.
