A braking assembly for an air disc brake comprises an actuator assembly having a service portion, at least one mounting stud attached to the service portion, and an air disc brake caliper having a bore for receiving the at least one mounting stud. The mounting stud is pivotable with respect to the service portion for installation on the air disc brake caliper.

Pivotable actuator mounting device

A disc brake for a vehicle, in particular for a commercial vehicle, is provided. The disc brake includes at least one application-side brake pad and a back-side brake pad held in a form-fitting manner in a brake carrier. At least the application-side brake pad is provided with at least one pad-retaining spring which is supported at least on one brake carrier horn of the brake carrier and exerts a radially outwardly acting tensile force on the brake pad.

Disc brake and set of brake pads

A disc brake caliper includes actuator and reaction portions disposed on opposite sides of a rotor and a bridge portion extending between the actuator and reaction portions and disposed radially outward of the rotor. The actuator portion houses a piston and a lever and defines a mounting flange for a brake actuator. Movement of the lever by the brake actuator causes the piston and the reaction portion to urge brake pads against opposite sides of the rotor. The mounting flange defines a pushrod bore and a fastener bore that receive a pushrod of the actuator and a shank of a fastener extending from the actuator, respectively. The fastener bore has a diameter that varies along at least a portion of a length of the bore beginning from a first end of the bore proximate the actuator and tapering moving towards a second end of the bore distant from the actuator.

Caliper for a disc brake configured to facilitate attachment of a brake actuator

A disc brake for a vehicle, in particular for a commercial vehicle, includes a brake carrier which receives at least two brake pads in respective clamping side and rear side pad slots, with the at least one brake pad on the clamping side being held in its pad slot in a form-fitting manner. The at least one brake pad on the clamping side is provided with at least one pad retaining spring which is supported at least on a brake carrier horn of the pad slot of the brake carrier. The at least one clamping spring exerts a tensile force acting radially outward on the brake pad. A brake pad set for the disc brake is also provided.

Disc brake and brake pad set

A system and method are provided for mounting, removing and retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles, in a manner which does not require the use of separate brake pad retaining devices while providing positive retention of the brake pad. A preferred embodiment includes a brake caliper mount having brake pad abutment surfaces having radially-oriented and lateral grooves which permit a brake pad with corresponding projections on is lateral sides to be inserted through an opening of the brake caliper into the radially-oriented grooves until the backing plate projections are aligned with the lateral groove, and advancing the brake actuator behind the brake pad to place the brake pad in an operating position in which the actuator prevents the brake pad from realigning with the radially-oriented grooves until the actuator is retracted to permit brake pad extraction.

Disc brake pad mounting and retention system and method

An apparatus and method are provided for suppressing undesired brake pad motion during brake application, and for installing and removing brake pads utilizing the inventive arrangements. One embodiment of the invention includes brake pads and a carrier mount having complementary surface features that retain the brake pad when the brake pad is in its installed position and a brake pad biasing structure that biases the brake pad in the radially outward direction to bias contact faces of the mount horn and the brake pad against one another to suppress brake pad kick and vibration and related wear and component fatigue.

Disc brake pad retention system and mounting method

Disc brake pad

A wear adjuster, securable to disc brake caliper structure includes, a stem extending along an axis about which the stem is rotatable in opposite directions, a spindle driver securable to an axial end of the stem to transmit rotational motion of the stem to an adjusting spindle, and an input element receiving input force supplied to the wear adjuster to produce rotation of the stem. A running clearance element is rotatable together with the input element to a limited extent, and a ratchet arrangement, located between the input element and the running clearance element, initiates any necessary adjustment for wear after rotation of the input element beyond the limited extent, and completes such adjustment during return rotation of the input element. To avoid transmitting an excessive amount of the input force received by the input element, a lost motion connection is defined between the ratchet arrangement and the input element.
