An electrically or pneumatically activated disc brake for a commercial vehicle includes: a brake disc having a preferred rotating direction; a brake carrier; a brake caliper guided so as to be displaceable on the brake carrier; a tensioning-side brake pad and a reaction-side brake pad which, in a tensioning-side pad take-up and in a reaction-side pad take-up, are disposed so as to be displaceable parallel to a brake disc rotation axis; and a tensioning device which has a single compression piston with a central axis and which on an end facing the tensioning-side brake pad has a compression piece which by way of a compression face acts on a corresponding counter bearing face of the tensioning-side brake pad such that, when tensioning the brake, an effective area is configured between the compression face and the counter bearing face. The tensioning-side brake pad and the reaction-side brake pad in the circumferential direction are aligned so as to be centered in terms of the brake disc and the central axis of the piston. The effective area, on which the compression face and the counter bearing face bear on one another when tensioning the disc brake, in the circumferential direction lies so as to be offset toward the egress side in terms of the preferred rotating direction of the brake disc and the central axis of the piston.
