A brake component positioning assembly that is removably connectable to a component of a heavy-duty vehicle. The brake component positioning assembly enables a brake system component to be positioned away from a wheel end of the heavy-duty vehicle to allow removal or servicing of at least one component of a wheel end assembly or the vehicle brake system. In one embodiment, the brake component positioning assembly includes a base block disposed in a cutout of a torque plate. A positioning block slidably engages one or more guide pins received by or disposed through the base block. A positioning bolt threadably engages the positioning block, whereby upon rotation of the positioning bolt, the positioning block and brake system component are positioned away from the bottom block and wheel end. Components of the brake component positioning assembly can be removably connected to each other.

A brake device includes a brake caliper with a first frictional surface and a first actuation surface, a pressing part of the brake device being linearly guided along a first straight line on the brake caliper. The pressing part has a second frictional surface and a second actuation surface, a region being provided between the first frictional surface and the second frictional surface for arranging a brake element. The brake device has a rotatable spreading element which interacts with the first actuation surface and the second actuation surface. During a rotation of the spreading element, the rotation occurring in order to actuate the brake device, a first spreading element surface is in direct contact with a first rolling surface and rolls substantially on the first rolling surface, and the first rolling surface corresponds to the first actuation surface or the second actuation surface.

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.

A floating disc brake includes a yoke supported to the support in an axially movable manner, the yoke including a pad support portion that supports an outer pad on an axially outer side of the outer pad. The outer pad includes, on its axially outer surface, a pair of pad-side engagement portions formed of an elastic material. The pad support portion has a support hole that is open on at least an axially inner surface of the pad support portion, and the support hole is provided with a pair of yoke-side engagement portions on inner side surfaces of the support hole that face each other in a circumferential direction. The pair of pad-side engagement portions and the pair of yoke-side engagement portions are concavo-convex engaged with each other in the circumferential direction.

An electrically or pneumatically activated disc brake for a commercial vehicle includes: a brake disc having a preferred rotating direction; a brake carrier; a brake caliper guided so as to be displaceable on the brake carrier; a tensioning-side brake pad and a reaction-side brake pad which, in a tensioning-side pad take-up and in a reaction-side pad take-up, are disposed so as to be displaceable parallel to a brake disc rotation axis; and a tensioning device which has a single compression piston with a central axis and which on an end facing the tensioning-side brake pad has a compression piece which by way of a compression face acts on a corresponding counter bearing face of the tensioning-side brake pad such that, when tensioning the brake, an effective area is configured between the compression face and the counter bearing face. The tensioning-side brake pad and the reaction-side brake pad in the circumferential direction are aligned so as to be centered in terms of the brake disc and the central axis of the piston. The effective area, on which the compression face and the counter bearing face bear on one another when tensioning the disc brake, in the circumferential direction lies so as to be offset toward the egress side in terms of the preferred rotating direction of the brake disc and the central axis of the piston.

A friction pad carrier for a vehicle disc brake includes a frame having an aperture through which a portion of a rotor rotating about a rotational axis extends. The frame mounts friction pads on opposite sides of the rotor. The frame includes lugs proximate each end that receive fasteners coupling the frame to an anchor plate mounted on an axle of the vehicle. The fasteners permit some amount of surge movement and sway movement between the frame and the anchor plate in a plane at the interface between the frame and the anchor plate and yaw movement about an axis perpendicular to the plane. A first alignment pin between one of the lugs and the anchor plate inhibits the amount of surge movement and sway movement and a second alignment pin between one of the lugs and the anchor plate inhibits the amount of yaw movement.

A braking assembly for inhibiting rotation of a wheel around a rotation axis is provided. The braking assembly includes a drive gear, an actuator, an electric braking assembly, a mechanical braking assembly including a brake pad, and a brake rotor fixedly coupled to the wheel. The drive gear rotates with the wheel and includes a pinion. The electric braking assembly includes a coil surrounding the rotation axis, and a magnetic disc assembly concentric with the coil and configured to rotate relative to the coil. The magnetic disc assembly includes a plurality of magnets at a perimeter of the disc. The actuator engages the pinion to inhibit rotation of the magnets and generate an electro motive force to inhibit rotation of the wheel. The actuator engages the brake pad to contact the rotor and inhibit rotation between the wheel and the brake pad.

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 suspension upright assembly for a vehicle provides a wheel hub bearing and a suspension upright including a fiber-reinforced composite bushing arranged around the wheel hub bearing, attachment members for attaching the suspension upright to a suspension assembly and to a brake caliper of the vehicle, and a fiber-reinforced composite truss-structure that connects at least one of the attachment members to the bushing and/or to a further one of the attachment members.

A brake caliper device is adapted to be used with a brake disk, and includes a main body unit, first and second pads, a caliper actuator unit, and a positioning unit. The caliper actuator unit includes an actuating member, a bolt member that abuts against the actuating member, and a threaded sleeve that is threadedly engaged to the bolt member. When the actuating member is driven by an external force, the actuating member is capable of vibrating axially to cause an axial vibration of the bolt member, which prompts the threaded sleeve to rotate relative to the bolt member for pushing the first pad toward the brake disk, thereby automatically providing a travel stroke that compensates for pad wear.
