A disc brake having an actuation mechanism, a disc brake rotor, first and second brake pad mounting structures, and first and second brake pads. The first and second mounting structures may have formations that affect fitting of the first and second pads.

Disclosed is an electric caliper brake. The electric caliper brake includes a carrier including a pair of pad plates installed to be moveable forward and backward, a caliper housing configured to be installed to be slidable on the carrier and to have a cylinder in which a piston of which an inside is dug in a form of a cup is moveable forward and backward due to a brake hydraulic pressure, a power conversion unit including a spindle member installed to pass through a rear of the cylinder and rotating due to a rotational force delivered from an actuator and a nut member screw-coupled to the spindle member, disposed in the piston, moving forward and backward according to rotation of the spindle member, pressurizing the piston, and releasing the pressurizing, and a filling member configured to be disposed in the piston in such a way that rotation of the filling member is limited, the filling member being coupled to the nut member.

A disc brake for a utility vehicle includes a brake caliper, designed as a sliding caliper and engaging over a brake disc, which is secured to a stationary brake carrier. Two brake pads, which are arranged in the brake caliper, can move inversely and have a respective pad carrier plate and a friction lining secured thereon, of which an action-side or application-side brake pad can be pressed against the brake disc by an application device via at least one brake piston. The brake pads are each accommodated in a pad housing of the stationary brake carrier, wherein the pad housing is formed by two opposing brake carrier horns and a longitudinal connector connecting the brake carrier horns. At least one of the brake pads is assigned a pad return device, with which the at least one brake pad can be returned after a brake-dependent shifting and releasing of the brake.

The present application relates to a friction brake system (1) for a vehicle. The friction brake system (1) comprises a braking member (12) connectable to first and second brake pads and configured for pressing the first and second brake pads against a friction surface. The system (1) further comprises a transmission unit (2) configured for converting a rotary motion generated by an electric motor (30) into a braking motion of the braking member (12). The transmission unit (2) comprises a ball-in-ramp assembly (3) having a first plate (9) with at least one groove (23), a second plate (10) with at least one groove (22) facing the groove (23) of the first plate (9), and at least one ball (11) arranged between the first plate (9) and the second plate (10). The ball (11) is retained by the groove (23) of the first plate (9) and the groove (22) of the second plate (10). Further, the ball-in-ramp (3) assembly is configured to convert a rotary motion of the first plate (9) into a translational motion of the second plate (10) with respect to the first plate (9). The first plate (9) is configured to be rotated by the electric motor (30). Further, at least one of the first plate (9) and the second plate (10) is mechanically coupled with the braking member (12). The first plate (9) is rotatably supported by a brake bolt bracket (16) coupled to a braking bolt (13), and the second plate (10) is operably connected to a caliper housing bolt (14) connected with a caliper housing (33) such that the caliper housing (33) and the braking bolt (14) are configured to press the first and second brake pads against opposing surfaces of a brake disc when the braking member (12) executes the braking motion.

A radial spring for a disk brake pad and brake pads and brakes provided with such radial springs, in which the radial spring is for the lug of a brake pad. The spring includes a clamp and a supporting loop. The clamp is formed of a straight arm, an undulating bottom, and an arm in the shape of a Z, followed by the loop connected by a bend, followed by a bend with a large radius of curvature connected to the pad terminated by a turn that is almost at a right angle to the extremity of the pad.

A brake calliper has two arms, where each arm includes a housing and a stub. A member for guiding a disc brake pad is disposed in the housing, and is secured by lugs to a front of the stub. The member includes a body having a U-shaped section formed by an inner radial surface, a base, and an outer radial surface. An inner side of the body is bordered by an inner supporting surface located on an inner surface of the arms, and an outer supporting surface of the body is disposed against a front of the stud. The out supporting surface extends into a supporting surface toward the front of the stud. The body further includes a locking tongue that extends beyond an edge of the body, and is configured to be hooked in the housing.

A brake assembly is provided. The brake assembly includes: a brake rotor configured to be rotatable with a wheel of a vehicle; a brake pad assembly configured to be engageable with the brake rotor; an actuator assembly having an electric motor configured to mechanically move the brake pad assembly toward or away from the brake rotor; and an abutment clip. The abutment clip includes: a first holding portion configured to hold the abutment clip against a caliper; and a second holding portion configured to hold a brake pad of the brake pad assembly, the second holding portion having an inclined loading leg.
