A disc brake for utility vehicles includes a brake disc, a first brake lining on a first side of the brake disc and a second brake lining on a second side of the brake disc opposite the first side. A spreading device is also provided which generates a force that moves the first and the second brake lining away from one another.

A brake assembly having a retraction spring and a method of assembly. The retraction spring may extend between first and second brake pad assemblies. The retraction spring may include a coil and, may have an end or tip that may be received in a hole in a backplate of a. brake'pad assembly.

A brake caliper arrangement includes a housing, a restoring device, a first brake lining arrangement and a second brake lining arrangement. The first brake lining arrangement and the second brake lining arrangement can be moved relative to one another from a respective starting position with a reduction of an initial spacing which exists between them. The restoring device includes first and second restoring elements. The first restoring element may prestress the first brake lining arrangement into its starting position, while the second restoring element may prestress the second brake lining arrangement into its starting position. The first and/or second restoring elements may be supported, on both sides of a central region of the brake lining arrangement, on the associated brake lining arrangement. The first and/or second restoring elements may be twisted elastically at least in sections in order to generate the prestress.

A pad spring has a guide part which is attached to come into contact with an inner side surface and a bottom surface on an outer side in a disc radial direction of a pad guide, and guides the friction pad in a disc axial direction, and an extension part which extends from the guide part in a direction away from the friction pad and comes into contact with a side surface of a torque receiving part of the attachment member by a projecting piece part on a distal end side to press the side surface of a torque receiving part. The extension part is provided with a pressing operation part which is pressed to move the projecting piece part in a direction away from the side surface of the torque receiving part.

A disc brake for utility vehicles includes a brake disc, a first brake lining on a first side of the brake disc and a second brake lining on a second side of the brake disc opposite the first side. A spreading device is also provided which generates a force that moves the first and the second brake lining away from one another.

A pad-holding spring and pad return spring assembly for a brake caliper may have a caliper body adapted to be arranged straddling a brake disc and a one pad-holding spring configured to be arranged between at least one guiding ear of a brake pad housed in the caliper body and the caliper body to bias the brake pad, and a pad return spring configured to bias the brake pad away from a brake disc. The pad-holding spring may have one C-shaped section. The pad return spring may have an anchoring portion operatively connected to the C-shaped section, a coupling portion configured to couple the brake pad, and a linking arm. The coupling portion is elastically movable with respect to the anchoring portion between a retracted resting position and at least one advanced position, towards the disc, and vice versa.

A pad-holding spring and pad return spring assembly for a brake caliper may have at least one pad-holding spring arranged between at least one guiding ear of a brake pad and a caliper body to bias the brake pad, and a pad return spring. The pad-holding spring has a main extension and at least one C-shaped section. The pad return spring may have an anchoring portion connected to the C-shaped section, a coupling portion to couple the brake pad, and a linking arm connected to the anchoring portion and the coupling portion. The coupling portion is movable with respect to the anchoring portion between a retracted resting position and at least one advanced position, towards the disc, and vice versa. The pad return spring may have at least one winding portion connecting the linking arm to the anchoring portion.

A brake device includes a caliper body, a brake pad disposed on the caliper body and including a friction member positioned on a first surface thereof and side protrusions protruding from left and right side surfaces of the brake pad, a return spring having one side coupled to the side protrusion of the brake pad and the other side coupled to the caliper body, and a load spring having one side coupled to the side protrusion of the brake pad and the other side coupled to the caliper body, and supporting a weight in a vertical direction of the brake pad. As a pad liner is removed and the three functions of the pad liner are separately achieved, a size of an unnecessary member is reduced and a performance is improved.

A disc brake for a utility vehicle has a brake caliper which fits around a brake disc, is in the form of a sliding caliper, is fastened to a stationary brake carrier and has a central opening over the brake disc. The disc brake has two brake pads which are arranged in the brake caliper, can be moved in opposite directions and each have a pad carrier plate and a friction lining fastened thereto, and of which an action-side brake pad can be pressed against the brake disc by a tensioning device via at least one brake piston. The disc brake also has at least one spreading device with which the brake caliper can be returned after a displacement caused by braking and after a release of the brake. The spreading device has resilient spring units which act on the mutually opposing brake pads. The spreading device is arranged in the central opening, and the spring units act directly or indirectly outside the friction linings in at least two attachment interfaces, spaced from each other and from the center, of the brake pads. The spring units are connected to a stationary attachment element in at least one connection interface by at least one connection element.

A retraction spring comprising: (a) a body portion; (b) a first end; and (c) a second end, the second end connected to the first end via the body portion, wherein the retraction spring is configured to connect between mounting points of a caliper housing and attachment points along a bottom peripheral edge of one or more brake pad assemblies.
