An improved electromechanically drivable spreader unit having an integrated adjustment apparatus for a drum brake, in which the linear motion of brake shoe holders is produced by two ball-ramp devices, wherein a first ball-ramp device includes a first actuation piston arranged for rotation about the axis and a second ball-ramp device includes a second actuation piston arranged for rotation about the axis, and wherein an adjustment apparatus for compensating an actuation travel that increases as a result of wear on the friction linings is arranged in an axially centered position within the housing and substantially between the actuation pistons.

The invention relates to a pad clip (5), comprising at least one retainer (6) for supporting a brake pad (2), and at least one retraction spring (10) for retracting the brake pad (2) in an axial direction upon a brake release, the retraction spring (10) having a spring body (17) with a first portion (11), a second portion (12), and an intermediate portion (13) connecting the first and second portions (11, 12), the first portion (11) comprising a contact portion (14) for contacting the brake pad (2), the second portion (12) being configured to be attached to a calliper support bracket (3), wherein the material of the first portion (11) axially extending between the contact portion (14) and the intermediate portion (13) is configured to be stretched in the axial direction upon a brake action and to return to its unstretched state upon a brake release. The invention also relates to a calliper support bracket (3) and a brake assembly (1).

A disc brake includes a brake caliper that engages over a brake disc and is designed as a sliding caliper. The disc brake has two brake pads which are located in the brake caliper, can be moved in opposite directions and each of which has a pad backing plate with a friction lining secured thereon. An action-side or application-side brake pad of the two brake pads can be pressed against the brake disc by a brake application device with the aid of at least one brake plunger. The brake also includes at least one restoring device, by which the brake caliper can be returned after a displacement and release of the brakes caused by a braking action. The restoring device has a spreading device which engages on the brake pads lying opposite one another and which acts with an identical force in opposition to the respective application direction. The spreading device includes spring-loaded spreading elements, each engaging on its respective pad backing plate. The spreading device is located in the central opening and the spreading elements engage directly or indirectly, outside the friction linings, on at least two contact regions of the brake pads, the regions facing each other at a distance from the center. Each contact region has a contact surface and a support surface, on which surfaces the spreading elements are movably located.

A resetting device by which a brake caliper can be reset after a braking-induced displacement and release of a brake. The resetting device has a spreading device which has resilient spreading elements. The spreading device is arranged in a central opening of the brake caliper. The spreading elements engage, outside the friction pads, directly or indirectly on one side at at least two abutment regions arranged spaced apart from one another relative to the center, of the brake pads, where the abutment regions have one abutment surface and one bearing surface on which the spreading elements are movably arranged. The spreading device has spring arms, of which in each case two lie against an associated pad carrier plate, where the spring arms are connected to one another in the central region of the opening. The spring arms are connected to a retaining bow which is attached to a brake carrier.
