A rotational fixing for a guide pin of a disc brake and method for fixing a guide pin of a disc brake. The rotational fixing includes a guide sleeve having a sleeve portion, a receiving portion of a brake carrier, and an inter-connection. The receiving portion receives the sleeve portion. The inter-connection engages the sleeve portion and the receiving portion and restricts rotation of the guide sleeve relative to the brake carrier when the sleeve portion is received by the receiving portion.

A motor vehicle disc brake including a cover (12) including two bores, a sliding caliper, two pins (16) for guiding the caliper, each whereof includes a guiding section (24) which is slidably mounted in a section (28) of a bore wherein each pin (16), engaging with the wall of the bore (29), defines an axial channel (65), and each pin (16) receives a tubular sealing cap wherein an inner wall includes at least one radial groove or a radial channel communicating with the axial channel (65) defined by the associated pin.

A caliper guide system for air disk brakes that provides a means of continuous maintenance, lubrication. The system includes a tubular guide pin, a cap, a grease valve, and a plurality of lubricating grooves. The tubular guide pin attaches a caliper head to a carrier of the air disk brakes to allow for relative motion. The lubricating grooves injects grease into the system and are radially distributed about the tubular guide pin. Each of the lubricating grooves normally and externally traverses into the tubular guide pin. The cap and grease valve seal off the tubular guide pin and allow for grease injection to the lubricating grooves. The cap is concentrically positioned about the tubular guide pin. The grease valve is adjacently integrated into the cap, opposite to the tubular guide pin. Resultantly, the grease valve is in fluid communication with each of the lubricating grooves.

The invention concerns a guide pin for a brake caliper assembly and a brake caliper assembly for a vehicle disc brake, the vehicle disc brake comprising a brake disc that rotates about a rotation axis, the brake caliper assembly comprising: a brake caliper housing having a receiving section for a brake piston; a brake pad carrier configured to slidingly receive a pair of brake pads; and at least one guide pin configured to guide a relative movement between the brake caliper housing and the brake pad carrier. At least a first section of the guide pin has a cross-section comprising a main axis and a minor axis. A dimension of the cross-section along the main axis is longer than along the minor axis. An angle enclosed by the main axis and a radial direction is smaller compared to an angle enclosed by the minor axis and the radial direction.

The invention relates to a disk brake for a utility vehicle, comprising a brake caliper, which extends over a brake disk and which is slidably held on at least one guide bar, which is connected to a stationary brake bracket by means of a screw, wherein the screw is fed through the guide bar, is designed in such a way that the guide bar has impressing elements, which are formed on the end face of the guide bar that lies against the brake bracket, at least in a circumferential and/or radial partial region, which impressing elements engage into the brake bracket in an impressed manner in such a way that an interlocking connection and/or a frictional connection is formed.

Provided is a disc brake which solves, with a simple structure, the issue of interference between a carrier and an electric motor. A carder 3 applied to the disc brake includes a recess 28 in one arm 18 of the pair of arms 18 and 19 which recess is casted so as to be recessed in a direction toward a line, which is parallel to a tangent line L3 tangent to an the pin hole boss 16 on one side and perpendicular to a line segment L1 connecting centers of the pair of pin holes (pin hole bosses 16, 16) and extends through the center of the pin hole on the one side, with respect to the tangent line L3. This makes it possible to prevent or reduce the interference between the carrier 3 and the electric motor, with a simple structure.

A multiple function brake caliper guide pin for use with a wireless transmitter to transmit brake wear data is disclosed. The pin is part of a brake assembly that includes a brake caliper, a caliper yoke for supporting the caliper in relation to the rotor, opposed brake pads, a wear sensor, and a brake wear sensing assembly comprising a brake caliper guide pin and a wireless transmitter system. The guide pin may be either of a two-piece or a one-piece design and includes a transmitter system attachment end and a yoke attachment end. The transmitter system includes a sensor for sensing brake pad wear and a wireless transmitter for transmitting the sensed wear to a receiver in the vehicle. The sensor may include a tether attached to a brake pad or may include a transmitter and magnet assembly fitted to one or the other of the caliper or the yoke.

The invention relates to a disc brake comprising a brake calliper (1) engaging over a brake disc (2) and brake pads (3) on both sides of the brake disc, a hold-down means (10) for the pads securing the brake pads (3) against falling out of the disc brake, which extends, in contact with the rear plates (5) of both brake pads (3), in the transverse direction in relation to same, and comprising a flat spring (12) which is spring-elastically in contact with the side of the hold-down means (10) for the pads facing away from the brake pads (3), which extends in the longitudinal direction thereof, and which is supported with both spring ends (31, 32) thereof in spring abutments (21, 22). A securing means (8) is a component of one of the spring abutments, which extends transverse to the hold-down means (10) for the pads and to the flat spring (12). In order to improve and simplify the assembly of the hold-down assembly by technical means, e.g. after exchanging the brake pads, according to the invention, a further component of the hold-down means (21) of the spring is a clip (40) which is connected to the brake calliper (1) via the securing means (8), and with which the inner side (45) of the spring end (31) facing the securing means (8) is in contact.

A disc brake assembly comprises an anchor bracket having at least one bore formed therein; a guide pin configured to be slidably supported in the bore and having a stem; at least one main damper configured to be disposed between the stem and an interior surface of the bore and configured to bias a portion of the stem against the interior surface of the bore depending upon brake loading on the disc brake assembly; and at least one secondary damper configured to be disposed between the stem and the interior surface, wherein the secondary damper is configured to limit a contact between the stem and the interior surface depending upon brake loading on the disc brake assembly.

A brake caliper (100) includes a bolt guide (110) for axially displacing the brake caliper (100) on a brake carrier. A bolt (122) is received axially displaceably in the bolt guide (110), the bolt (122) having a bushing (124) arranged around the bolt (122). In addition to the bushing (124) and adjacent thereto, the brake caliper (100) has at least one damping element (130), the damping element (130) circumferentially surrounding the bolt (122) and being designed to damp a relative movement in the radial direction between the bolt (122) and the bolt guide (110). A kit for a bolt guide (110) of a brake caliper (100) includes the bolt, the bushing, and the damping element.
