A guide means for a brake lining arrangement of a disc brake wherein a lower securing portion has at least one lower retaining portion which engages into a corresponding recess in a brake support and is thereby in secure engagement with the brake support at least in some sections. Furthermore, a stop surface has an upper retaining portion, which has two regions that can be brought into contact with the brake support at least in some sections for positioning purposes, the upper retaining portion being arranged on a guide means such that the retaining portion fixes the guide means axially in both directions when attached to the brake support.

An electromagnetic brake (10) including a plurality of elastic members (25) which are arranged between an engagement surface of a brake pad (13) and an engagement surface of a hub (12) symmetrically about a center of rotation of the shaft (11). The biasing directions of the plurality of elastic members are in a rotational direction of the shaft.

A brake assembly having a brake carrier, a caliper, first and second brake pads, a pad retraction spring, and a first stop surface. The pad retraction spring urges the first and second brake pads in a direction away from a rotor plane. A first supporting portion of the pad retraction spring is configured to abut the first stop surface to inhibit the pad retraction spring from entering a partially enclosed volume.

A multi-disk brake assembly includes a stator disk that is non-rotatable, a rotatable rotor disk arranged adjacently and coaxially with the stator disk, and an axial retention device. The rotor disk and the stator disk are axially moveable between an engaged position during braking operation and a disengaged position during a released mode of operation. The axial retention device is axially moveable and supports at least one of the disks. The axial retention device includes a set of axially translatable pins or bolts that are pushed by the disks during the braking operation and maintain a predetermined space between the disks during the released mode of operation. The predetermined space and position of the disks is maintained when the brake assembly is subject to forces due to vehicle acceleration or cornering.

A brake drum system (100) for a wheel of a vehicle, comprising a brake drum (110) rotatable with the wheel, the brake drum having an inner surface (124) adapted to receive a friction-generating lining when a driver applies the brakes of the vehicle; a wheel end hub (112) adapted to be located radially between a drive axle of the vehicle and the brake drum (110); and a substantially circular spring element (102) for concentrically aligning the brake drum (110) with the wheel end hub (112), the spring element being adapted to be clamped between the brake drum and the wheel end hub for providing a radially directed spring force, wherein the spring element has an outer surface adapted to be pressed against the brake drum and an inner surface adapted to be pressed against the wheel end hub.

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.

An attachment structure is a structure that attaches an annular brake disk to an attachment object member that is a wheel or a disk body of a railway vehicle. The attachment structure includes a fastening member and an elastic member. The elastic member is disposed between a nut of the fastening member and the brake disk. The elastic member has a member body having a tubular shape, and a flange. The flange is connected to an end part on the nut side among two end parts of the member body. The flange protrudes outward from the member body and contacts an outer peripheral portion of the nut.

A brake pad retraction spring that includes a coil, first and second biasing arms, and first and second biasing tips. The first and second biasing arms may extend from the center coil. The first and second biasing tips may extend from ends of the first and second biasing arms, respectively.

At least one of a pair of pad springs includes a guide plate portion for guiding an ear portion of a corresponding friction pad in a disc axial direction. The guide plate portion includes a first plate portion, a second plate portion, and a bottom plate apportion. A radially biasing portion is configured to elastically bias the ear portion of the friction pad toward the first plate portion; and a rotational direction biasing portion is configured to bias the friction pad in a rotational direction of a disc. The second plate portion is provided with an open portion at a position shifted inward from a middle position in the disc axial direction. The rotational direction biasing portion includes a main biasing portion configured to bias the friction pad inward in the disc rotational direction, and a sub biasing portion arranged across the open portion away from the main biasing portion.

Brake calipers and rotors for bicycles are described herein. An example brake caliper includes an outboard caliper portion to be disposed inboard of a frame of the bicycle. The outboard caliper portion includes an outboard caliper body and an outboard brake pad that is fixed relative to the outboard caliper body. The brake caliper also includes an inboard caliper portion coupled to the outboard caliper body. The inboard caliper portion is disposed inboard of the outboard caliper portion when the brake caliper is coupled to the bicycle. The inboard caliper portion includes an inboard caliper body and an inboard brake pad that is movable relative to the inboard caliper body.
