A disc brake for a utility vehicle is provided. The brake caliper of the disk brake is configured to be mounted in an axially-displaceable manner on a stationary brake carrier by two fastening elements. The two fastening elements are plain bearings arranged in respective bores of the brake caliper, one as a locating bearing and the other as a floating bearing. The floating bearing includes a sliding bush made from a plastic, in particular an elastomer, and a guide rod configured to be connected to the brake carrier is mounted. The sliding bush is held on the guide rod secured against axial displacement between the guide rod and the inner wall of the respective brake caliper bore. The sliding bush is configured to carry a lubricant on its circumferentially outer surface and has sealing lips projects radially outward that bear against the inner wall of the respective bore.

A disk brake with lower cost and improved maintainability is provided. The brake caliper includes at least one actuating device for actuating the disc brake using a moveably guided bridge. The bridge has at least one threaded hole into which an actuating spindle is displaceably located. A brake disk end of the actuating spindle penetrates a caliper closing plate facing the brake disk. The positioning spindle carries a rotatably-mounted pressure piece which presses a brake pad against the brake disc. The opening is sealed by a bellows retained on the brake caliper on one side and on the pressure piece on the other side. A securing ring non-rotatably located on the actuating spindle and rotatably connected to the thrust piece interacts with the bellows during brake application and/or release to maintain a desired air gap between the brake disk and brake pad.

A guide assembly for a disc brake and method of mounting. The guide assembly may have a guide pin that includes a mounting portion and a guiding portion. A retaining bore of a brake carrier may receive the guide pin and retain the mounting portion. The guiding portion may protrude from an inboard-side of the brake carrier and may slidably support a brake caliper.

A disc brake assembly includes an anchor bracket, a guide pin, a sliding mechanism, and a damping member. The anchor bracket may have at least one bore formed therein. The guide pin may be adapted to be disposed in the at least one bore and slidably support a brake caliper relative to the anchor bracket. The sliding mechanism may be adapted to be disposed in the at least one bore and to slidably support the guide pin in the at least one bore. The damping member may damp sliding motion of the guide pin relative to the anchor bracket.

A caliper guide assembly having a guide pin, a guide bore, a cap, and a sensor arrangement. The guide bore is arranged to receive the guide pin. The cap may be secured to an open end of the guide bore proximate a free end of the guide pin. The sensor arrangement may include a first sensor component that is configured to provide an output indicative of relative axial displacement between a first sensor component and a second sensor component.

A brake system for a vehicle is disclosed. The brake system includes a wheel hub, a brake disk, and a brake caliper. The wheel hub includes a hub and attachment posts. The hub defines a bore adapted to receive an axle of the vehicle. The attachment posts extend away from the hub adjacent to the bore. The attachment posts are singularly and integrally formed with the hub. The brake disk is disposed adjacent the wheel hub. The brake caliper includes a piston housing and a body. The piston housing is adapted to hold a piston. The piston housing defines mounting holes used to movably mount the brake caliper directly to the wheel hub at the attachment posts. The body is positioned radially outward of the brake disk. The piston housing and the body are integrally formed as a singular component.

A floating caliper may have a caliper body where the caliper body is movably supported in an axial direction on at least at one guide pin. The guide pin may have a pin sliding portion. The caliper body may have a pin seat, which slidingly accommodates a portion of the pin sliding portion. The floating caliper may also have a sealing arrangement between the pin seat and the guide pin. A sealing arrangement outer surface or a sealing arrangement inner surface may have an axial extension, which is smaller than a pin seat axial extension or the length of the pin sliding portion, respectively, creating, in at least one position of the floating caliper during the axial sliding thereof, at least one sealing arrangement channel between the sealing arrangement and the pin seat or the pin sliding portion.

An electromechanical brake apparatus includes a housing supporting an inboard brake pad and an oppositely facing outboard brake pad for selective frictional contact with a rotor interposed longitudinally therebetween. The housing includes a mechanism cavity located longitudinally between the inboard pad and a motor having a motor output shaft. An adjuster ramp assembly indirectly receives torque from the motor. A spindle is operatively connected with the adjuster ramp assembly to indirectly receive torque from the motor therethrough. A leading ramp assembly is configured to transmit applied torque from the motor to the adjuster ramp assembly. The leading ramp assembly receives stepped-up torque from the motor via the motor output shaft and a ball thrust bearing at least partially located radially between the motor output shaft and an actuator ramp of the leading ramp assembly.
