An electromechanical frame brake is disclosed. The electromechanical frame brake comprises a floating frame assembled from a plurality of parts, and a brake piston, which can be moved axially by a spindle drive and is seated on a spindle of the spindle drive and guided in a piston-receiving housing. The floating frame has the piston-receiving housing, lateral struts, and an outer crossmember, which is connected via the struts to the piston-receiving housing. The crossmember carries an outer brake pad. The floating frame is mounted by way of axial linear guides in a brake carrier of the frame brake in such a way as to float and to be axially movable relative to the brake carrier. The brake carrier has a socket with a guide surface for the piston-receiving housing, which is mounted in an axially movable manner in said socket.

A disc brake for a utility vehicle includes a brake caliper that is in the form of a sliding caliper and overlaps a brake disc; two brake pads which are located in the brake caliper, can be moved in opposite directions in the direction of the brake disc, each have a pad backing plate and a friction lining fastened thereto, and are each located in a pad shaft of a vehicle-side brake carrier, which pad shaft is delimited in the direction of rotation of the brake disc by brake carrier horns; and at least one restoring device by which the brake pads can be restored after a braking-related movement and release of the brake. The restoring device has at least one restoring element which is attached to a brake pad, is located between the brake pad and a stationary component, and exerts a restoring force on the brake pad, the at least one restoring element being in the form of a leaf spring which is fastened on the rear side of the pad backing plate facing away from the friction lining and has a spring arm which extends in the peripheral direction of the brake disc and is supported against the brake carrier as a stationary component.

In some examples, a brake system is configured to compress a brake disc stack to reduce and/or limit rotational motion of a wheel about a wheel axis. The brake system is configured to transmit a compression force on the disc stack to a plate member, such as a backing plate. The plate member may be configured to transmit the compression force to a support member such as a torque tube via one or more torque pads. The brake system includes a coupling system configured to couple the plate member and the support member. The coupling includes an elastic member configured to exert a force on a pin in a direction opposite the compression force to assist in keeping a locking tail of the pin engaged with the support member.

A brake assembly includes a brake disc rotatable about a rotational axis, a service brake assembly with a service brake pad and configured to apply a service brake force on a radial surface side of the brake disc, wherein the service brake pad is axially moveable with respect to the rotational axis and has a service brake braking surface facing the radial surface side of the brake disc to apply the service brake force, a park brake assembly with a park brake pad and configured to apply a park brake force on the or another radial surface side of the brake disc, wherein the park brake pad is axially moveable with respect to the rotational axis and has a park brake braking surface facing the or the other radial surface side of the brake disc to apply the park brake force. The park brake braking surface of the park brake pad is arranged at a radial park brake pad distance with respect to the rotational axis different from a radial service brake pad distance of the service brake braking surface of the service brake pad.

In some examples, a brake assembly is configured to compress a brake disc stack to reduce and/or limit rotational motion of a wheel about a wheel axis. The brake assembly is configured to transmit a compression force on the disc stack to a backing plate. The backing plate is configured to transmit the compression force to a torque tube via one or more torque pads. A torque pad includes a pin supported by a support portion of the torque pad. The pin is configured to insert into a support recess of a boss when the boss supports the torque pad. The support portion of the torque pad is resiliently biased, such that the support portion exerts an force on the pin in an inward direction when the pin is displaced in an outward direction opposite the inward direction.
