The present invention relates to a commercial vehicle disc brake caliper assembly comprising a caliper body and a left guide pin component, right guide pin component, the main adjuster mechanism assembly, the driven adjuster unit are all mounted on the caliper body. The adjuster mechanism assembly adopts a gear clutch structure with anti-overload function; the driven adjuster unit adopts a circlip structure; the main adjuster assembly and the driven adjuster unit is connected by sprocket chain. The bottom of the main adjuster assembly and the bottom of the driven adjuster unit are connected to the three thread calibration bolt, which connected with bridage, the bridage are arranged inside of the brake caliper. The invention overcomes the problems which may occur during braking, such as uneven braking force, failure of clearance adjustment, deformation of adjuster mechanism, failure of braking, etc.

A brake assembly having a guide pin assembly that slidably couples a brake caliper to a brake carrier. The guide pin assembly may include a resilient member that extends between a bushing and a sleeve. The sleeve may be mounted to the brake carrier. The brake caliper may be slidable along the bushing.

A caliper guide assembly and a method of manufacture. The guide assembly may include a guide pin, a guide bore arranged to receive the guide pin and permit relative axial sliding thereof, a bush arranged to define at least part of the guide bore, and a sensor arrangement configured to provide an output indicative of a state of wear of the bush.

A caliper guide assembly for a heavy vehicle disc brake. The caliper guide assembly may include a wear sensor arranged to detect the position of a guide pin in relation to a guide bore. The guide pin and a guide surface may have different cross sectional profiles to define at least one void therebetween. The wear sensor may be at least partially accommodated within the void.

Disclosed are a boot for a caliper brake and the caliper brake including the same. The boot, which is provided to be installed on a guide rod to allow a caliper housing to be slidably coupled to a carrier during braking, includes a first coupling part coupled to the guide rod at one end thereof, and a second coupling part coupled to the carrier at the other end thereof, wherein the second coupling part is provided with an elastic protrusion provided to be in contact with an outer surface of the guide rod so that a reaction force is generated by the guide rod moving together with the caliper housing during braking.

A floating disc brake includes an outer pad disposed on an axially outer side relative to a rotor, an inner pad disposed on an axially inner side relative to the rotor, a fixing member disposed on the axially inner side relative to the rotor, the fixing member being configured to support the inner pad to be movable in an axial direction and being fixed to a vehicle body, and a yoke supported to the fixing member by a slide pin to be movable in the axial direction, the yoke supporting the outer pad. The fixing member is provided with an anchor disposed on a radially outer side relative to the rotor, the anchor being configured to bear a brake tangential force that acts on the outer pad at the time of braking within a circumferential range of a lining constituting the outer pad.

A brake assembly having a guide pin assembly that slidably couples a brake caliper to a brake carrier. The guide pin assembly may include a resilient member that extends between a bushing and a sleeve. The sleeve may be mounted to the brake carrier. The brake caliper may be slidable along the bushing.

A disc brake guide assembly having a guide bush, a closure, and a stop. The guide bush may be mountable in a through bore of a support. The closure may be a barrier to the ingress of foreign matter into the through bore. The stop may restrict axial displacement of the guide bush.

The disclosure relates to a brake caliper guide for a floating caliper disk brake, comprising at least one guide pin attached to a brake caliper, having a head and a shaft, a brake carrier having at least one guide bore which has an entry region and a bore depth extending into the brake carrier, and a guide device inserted into the entry region of the guide bore having a sliding sleeve arranged in an elastomer sleeve 40. The shaft of the guide pin is mounted in a longitudinally displaceable manner in the sliding sleeve such that the head is located outside the brake carrier. The region of the shaft which is located on the side of the guide device oriented toward the bore depth projects into the guide bore. The end face of the sliding sleeve which is oriented toward the outer face of the brake carrier has a first collar which extends radially outwardly. The elastomer sleeve overlaps the sliding sleeve and adjoins the first collar and is delimited in the longitudinal extent thereof by this collar, and/or the end face of the sliding sleeve, which is oriented toward the outer face of the brake carrier, has a first collar which extends radially outwardly. The end face of the sliding sleeve has a second collar which extends radially outwardly. The elastomer sleeve is arranged between the first and the second collar and is delimited in the longitudinal extent thereof by the collars.

In accordance with one embodiment of the present disclosure, a guide pin allowing a caliper housing to be slidably coupled to a carrier during braking, includes a cylindrical guide shaft portion; and a head portion provided at one end of the guide shaft portion in an enlarged diameter form, and the guide shaft portion is provided in a form in which at least a portion of a center thereof is hollow in an axial direction to form a hollow portion.
