A pad support spring includes a U-shaped portion comprising an outer peripheral surface portion, an inner peripheral surface portion and a linking surface portion. The U-shaped portion is configured to include: a pad holding portion; a cutout portion provided by cutting out a part from the linking surface portion toward the inner peripheral surface portion; a tongue piece portion which in an unassembled state has a base end formed by the cutout portion on the outer peripheral surface portion side of the pad holding portion and a distal end which projects out from an opposing surface of the inner peripheral surface portion, and which in an assembled state deforms elastically to press a brake pad in conjunction with the U-shaped portion; and a first slit portion provided by cutting out part of a first linking part.

The invention relates to a restoring device (1) for restoring a brake pad of a motor vehicle disc brake, and to a motor vehicle disc brake which comprises a restoring device of this type.

The restoring device (1) comprises a wear compensation means (2) and a tension arrangement (7) for generating a restoring force, having a bearing region (10) for support on a brake carrier of the motor vehicle disc brake, and a coupling section (8), the bearing region (10) defining a bearing plane (AE) by way of a bearing contact (11) which, when the tension arrangement (7) bears against the brake carrier, comes into contact with the latter.

Furthermore, the restoring device (1) comprises a coupling device (4), by way of which the wear compensation means and the tension arrangement (7) are coupled to one another or can be coupled to one another in such a way that, in the coupled state of the wear compensation means (2) and the tension arrangement (7), it permits a perpendicular orientation of the wear compensation axis (VA) with respect to the bearing plane (AE) and an orientation of the wear compensation axis (VA) which differs from the perpendicular orientation and is inclined within a pivot angle range (a) towards the bearing plane (AE) in every extent direction of the bearing plane (AE).

A brake lining retention device for a disc brake of a motor vehicle. The brake lining retention device includes a brake carrier fixed at the vehicle side and having a lining shaft for receiving a brake lining, wherein the lining shaft is delimited at the brake disc leading side in relation to a main rotation direction of the brake disc and delimited at the brake disc trailing side by a lining horn-like member of the brake carrier. The brake lining retention device includes a brake lining guided in the lining shaft and has a lining retention member and a friction lining fixed thereto, and a resilient element supported on a lining horn-like member and a support face of the lining retention member, wherein the face is adjacent to the lining horn-like member and the resilient element is inserted in a recess of the lining retention member.

A brake lining arrangement for a vehicle brake with a friction lining and a lining backing plate, having a receiving portion arranged in its lateral edge region for receiving a separate damping element, which laterally grasps the lining backing plate, wherein the damping element has a contact portion for contacting a portion of a brake caliper corresponding with the contact portion, and the damping element is adapted to be deformable or/and displaceable at least in sections upon a contacting.

A caliper body has a first elongated vehicle-side element facing a first braking surface, a second elongated wheel-side element facing a second braking surface opposite to the first braking surface, each having at least one thrust seat receiving a thrust device biasing at least one brake pad against the braking surfaces, and at least one caliper bridge connecting the first elongated vehicle-side element to the second elongated wheel-side element. The caliper body has caliper fixing elements connecting the caliper body to a vehicle mount, the caliper fixing elements being at least three in number and distributed along the first elongated vehicle-side element. The first elongated vehicle-side element and second wheel-side element may have each at least two pad seats, each receiving at least one brake pad and at least two opposite abutment elements abuttingly receiving a brake pad for relieving the braking action on the caliper body.

A friction lining assembly having a backing plate and a sheet metal restoring spring fixed thereto, for a partially lined sliding-caliper type disk brake having a brake holder fixed with respect to the vehicle, on which friction lining assemblies arranged on both sides of a brake disk are slidably guided. A housing, which extends over the brake disk and the friction lining assemblies, is slidably mounted on the brake holder. The restoring spring is clamped axially between the brake holder and the friction lining assembly by at least one spring leg and applies a release clearance to the friction lining assembly. The spring leg extends over a hammer-head-shaped claw of the backing plate. The spring leg is plastically deformable in a defined manner under braking actuation as a result of a reduction in the friction-material thickness in order to impose a constantly dimensioned release clearance on the friction lining assembly.

A brake pad retractor system, comprising, a torsional mount and an adjustable torsion arm having an angular relation with the torsional mount, wherein the torsion arm is sprung responsively to at least some movement of a brake pad and the torsional mount being operative such that upon movement of a brake pad by a first distance, the torsion arm is sprung and communicates an action upon the brake pad through a contact between the torsion arm and the brake pad, the communicated action sufficient to positively retract the brake pad upon release of the brake system, the torsional mount further operative such that upon further movement of a brake pad beyond the first distance the angular relation between the torsion arm and the torsional mount is adjusted responsively to the further movement. Further aspects include a novel a brake caliper and method.

A spring brake actuator is for braking a wheel of a vehicle. The spring brake actuator has an axially elongated housing having a parking brake chamber and a service brake chamber; a main compression spring in the parking brake chamber; a flexible diaphragm in the parking brake chamber; and a pressure plate in the parking brake chamber, the pressure plate located axially between the main compression spring and the flexible diaphragm. The flexible diaphragm has a contoured portion that inhibits radial shifting of the pressure plate with respect to the flexible diaphragm.

A brake system includes a series of rotors for operatively coupling to a shaft and stators for operatively coupling to a frame. A service brake system includes a singular annular service piston extending continuously around the series of rotors and stators and a parking brake system includes a singular annular parking piston positioned to extend continuously around the series of rotors and stators. The service piston nests with the parking piston, under a spring bias, such that the parking piston and service piston continuously engage together around the series of rotors and stators to thereby create the parking brake forces. Springs act on the parking piston to drive the parking piston and nested service piston to engage for parking brake forces. Pressurization of the parking piston deactuates the nested pistons. Then separate pressurization of fluid acts on the service piston to overcome the spring bias and separate the service piston from the parking piston to create service brake forces.
