A protective cover for a disc is for being disposed on a fork of a bicycle. The fork has a shaft hole. A direction toward which an opening of the shaft hole faces is defined as an axial direction. The bicycle further has a brake disc. The protective cover includes a shell body. As viewed in the axial direction, the shell body and the brake disc are located by the same side of the bicycle, and the brake disc is shielded by the shell body.

The application relates to a brake caliper for a disk brake system comprising a caliper bracket, a caliper housing, a first connecting means and a second connecting means, wherein the first connecting means and the second connecting means may each be configured to mount the caliper bracket to the caliper housing or wherein the first connecting means and the second connecting means may each be configured to mount the caliper bracket to an axle assembly, characterized in that a mass of the first connecting means is different from a mass of the second connecting means.

Provided is a caliper unit for a brake of a vehicle, in particular, a compact caliper unit capable of reducing a size, a weight, and a production cost of a component and improving fuel efficiency. The caliper unit for the brake includes an inner pad and an outer pad, which press both surfaces of a disc to generate braking force, a torque member fixed to a vehicle body and coupled to be movable forward and backward so that the inner pad and the outer pad press the disc, or the pressing of the inner pad and the outer pad to the disc is released, a caliper housing including a cylinder to which a brake hydraulic pressure is applied and a reaction force support part configured to press the outer pad to the disc, and a piston installed in the cylinder and moving forward and backward depending on a state of the brake hydraulic pressure applied to the cylinder to press the inner pad to the disc. Each of the inner pad and the outer pad has a circular shape, and a contact surface of the piston, which is in contact with the inner pad to press the inner pad during braking, has a circular shape.

A brake apparatus for a vehicle may include: a caliper part fixed to a vehicle body, and having a cylinder provided therein; a piston part movably installed in the cylinder, and brought into contact with or separated from a pad plate part according to a moving direction thereof; a shaft part configured to receive a driving force from a driving part, and reciprocate in a direction parallel to a longitudinal direction of the cylinder; a pressing part connected to the shaft part, and configured to press the piston part toward the pad plate part as the shaft part is moved to one side; and an angle adjusting part provided between the shaft part and the pressing part, and configured to vary an installation angle of the shaft part with respect to the pressing part.

The invention relates to a disc brake, comprising a brake carrier, a brake caliper, brake shoes, and an actuating piston. The brake carrier has at least one mounting point for mounting on a vehicle. The actuating piston is displaceably accommodated on the brake caliper and is actuatable for carrying out a service brake function of the disc brake. At least one further actuating piston is provided, which in the direction of its longitudinal axis is displaceably accommodated on the brake caliper. For carrying out the service brake function, the at least two actuating pistons are actuatable, and for carrying out a parking brake function, one of the actuating pistons is actuatable. The invention further relates to a disc brake system and a parking brake system.

A disc brake according to an embodiment of the present disclosure includes a cylinder body and a bracket assembly. The bracket assembly is disposed in a space in the cylinder body. The cylinder body and the bracket assembly are fastened to each other by fastening members.

A disc brake assembly that includes at least one brake pad retraction spring and a sensor assembly. The brake pad retraction spring extends between a pair of brake pad assemblies. The sensor assembly includes at least one sensor and a wire harness. The sensor is disposed on a brake pad assembly. The wire harness is attached to the brake pad retraction spring.

A disc brake assembly that includes a brake caliper, a retainer strap, and a sensor assembly. The retainer strap is mounted to the brake caliper and extends across a brake pad assembly. The sensor assembly is mounted to the retainer strap and generates a signal indicative of a position of the brake pad assembly.

The disclosure relates to a brake caliper for a disk brake, comprising a support structure having a bridge and at least one bridge finger. The at least one bridge finger has a brake lining side, an outer side, and a bore introduced into the outer side. The bore has a bore wall, a bore groove let into the bore wall. A cover having a pin projects into the bore and a pin groove extending into the pin circumferential surface, A sleeve is arranged between the bore wall and the pin circumferential surface and has a sleeve body

The sleeve has a spring arm which is bent outward in the radial direction away from the sleeve body and/or a spring arm which is bent inward in the radial direction away from the sleeve body. The outwardly bent spring arm engages into the bore groove and/or the inwardly bent spring arm engages into the pin groove.

The present disclosure relates to a brake caliper for a disk brake comprising a supporting structure having a bridge and at least one bridge finger. The at least one bridge finger has a brake lining side, an outer side and a bore, that extends into the outer side. The bore has a bore axis and a bore wall. A profiling is recessed into the bore wall. A faceplate having a peg, projects into the bore and has a peg circumferential surface. A sleeve, which has a sleeve body is arranged between the bore wall and the peg circumferential surface. The sleeve has a spring arm, which is bent outwardly in the radial direction away from the sleeve body. The profiling is designed in such a way that the outwardly bent spring arm can latch into the profiling at various points of the profiling in the axial direction of the bore axis.
