An air disc brake system includes a carrier having a mounting feature and a guide pin having a longitudinally extending relief passage. A caliper includes a longitudinally extending bore having spaced apart first and second ends, wherein the guide pin is received in the bore, and wherein the caliper is slidably mounted on the guide pin with the relief passage in fluid communication with the first and second ends of the bore. A fastener couples the guide pin to the carrier. A cap is coupled to the caliper and closes a second end of the bore. Methods of using and assembling the air disc brake system are also provided.

The caliper brake includes: a carrier fixed to a vehicle body, wherein a guide hole is formed in the carrier; a caliper housing movably installed in the carrier; a guide pin of which an end penetrates the caliper housing and is inserted in the guide hole to guide a movement of the caliper housing; a bush positioned between the guide hole and the guide pin and surrounding at least one portion of the guide pin; and a spring inserted in the bush.

A caliper brake (10) is adapted to act upon a stator (40) to engage a rotor of a vehicle. A housing (11) carries both a spring applied hydraulically released piston assembly (12) and a pressure intensifying piston assembly (14). The assemblies (12, 14) are in fluid communication with each other. The assembly (12) includes a piston (18) and a spring assembly (20) which urges the piston (18) into a first position engaging the stator (40). The piston assembly (14) includes a pressure intensifying (PI) piston (64) which is in a first position when the piston (18) is in the first position. When the PI piston (64) moves from a first position to a second position, the fluid acts upon the piston (18) thereby disengaging the piston (18) from the stator (40).

An air disc brake system includes a carrier having a mounting feature and a guide pin having longitudinally spaced first and second ends, a through hold having a first center axis and an outer cylindrical surface having a second center axis. The first and second axes are spaced apart a distance D such that the outer cylindrical surface and through hole are eccentric. A caliper includes a bore with spaced apart first and second ends. The guide pin is received in the bore, and the caliper is slidably mounted on outer cylindrical surface of the guide pin. A fastener is disposed in the through hole and includes a first end engaged with the mounting feature and a second end engaged with the guide pin. An eccentric guide pin, a tool for adjusting the eccentric guide pin, and methods of using and assembling the air disc brake system are also provided.

A vehicle disc brake assembly comprises a brake caliper and an anchor bracket. The brake caliper has a lug, a bore, an opening, a fastener, and a guide pin. The lug has first and second side faces. The bore extends from the first side face to the second side face. The opening is to the bore at the first side face. The fastener has a transition portion between a bolt stem and a bolt head. The transition portion is fitted to the opening. The guide pin is attached to the fastener. The anchor bracket is supported on the guide pin.

A disc brake assembly that includes first and second brake pads for contacting a rotor, a brake carrier for receiving at least the first brake pad, a brake caliper arranged to slide with respect to the brake carrier, and an actuating arrangement. The actuating arrangement is configured to selectively move the brake caliper and is electrically operated.

It is the object of the present invention a pad-holding pin and sliding guide assembly 4, 5 for a brake caliper 1 of the floating type of a disc brake, wherein the brake caliper 1 comprises a caliper body or floating element 2, a bracket or support element 3 configured to be connected to a vehicle,

in which the pad-holding pin and sliding guide assembly 4, 5 is connectable in a fixed manner to the bracket 3 and in a sliding manner to the caliper body 2 to allow for a relative sliding between the caliper body 2 and the bracket 3 along an axial direction A-A, in which the pad-holding pin and sliding guide assembly 4, 5 comprises a pad-holding pin 13, 13 and a sliding guide 10, 10 made in separate, reversibly connectable pieces, in which the pad-holding pin 13, 13 is configured to support at least one brake pad 52, 53 and in which the sliding guide 10, 10 is at least partially housable in a respective sliding seat 11, 12, in which the respective sliding seat 11, 12 is made in said caliper body 2; in which the pad-holding pin 13, 13 and the sliding guide 10, 10 comprise a pin connecting portion 17 and a guide connecting portion 24, respectively, connectable to each other by threaded connection to connect the pad-holding pin and sliding guide assembly 4, 5 in a fixed manner to the bracket 3 by tightening the bracket 3 on axially opposite sides between the pad-holding pin 13, 13 and the sliding guide 10, 10 avoiding having connecting threads between the at least one pad-holding pin and sliding guide assembly 4, 5 and the bracket 3.

A brake assembly including a caliper that has a first guide bore, a brake carrier arranged to receive a brake pad, a first guide pin secured to the brake carrier, and a first lock arrangement. The first lock arrangement is operable to selectively inhibit relative sliding between the caliper and the brake carrier.

A brake assembly for use with a rotating shaft such as on the wheel of a vehicle or on industrial equipment. The brake assembly includes a first brake pad, a second brake pad, a lever having a plurality of concave surfaces and corresponding plurality of convex surface, a bracket, a ball bearing moveable into and out of each of the plurality of concave surfaces and a spacer positioned between the lever and the second brake pad. The spacer contacts the lever radially outwardly of the convex surfaces.
