Brake shoe, in particular of a drum brake for utility vehicles, includes a lining plate and a bridge unit, wherein the bridge unit is formed as a one-piece body comprising at least two bridge plates.

A brake assembly apparatus is provided for a vehicle braking system. The brake assembly apparatus comprises a vibration damping sleeve for damping vibration between a first braking component and a second braking component. The sleeve includes (i) a first set of spring elements projecting toward a circumferential surface of the first braking component and tuned with a first preload against the circumferential surface of the first braking component, and (ii) a second set of spring elements projecting toward a circumferential surface of the second braking component and tuned with a second preload against the circumferential surface of the second braking component. The first and second sets of spring elements cooperate to damp vibration of certain frequencies between the first and second braking components based upon the first and second preloads.

Methods and corresponding control devices for releasing an electric actuator in a reliable manner, such as an electric parking brake in particular, in a motor vehicle brake system. The aim of the invention is to provide an improved function and architecture which helps prevent the disadvantages of open-loop control systems when using a rationalized sensor system, thereby obviating closed-loop control systems. This is achieved by a release method and a corresponding electronic control unit which obtains an especially modulated change in the power requirement during the release process upon impacting the quasi-elastic release end stop of the electric actuating unit such that the change is fed back, the change being detected in order to be used as information for a power interruption or a termination of the power supply to the electric actuating unit.

A novel, particularly rationally designed, modular parking brake actuator for an electric drum brake system. An axle A1 from the motor, including a screw gear pinion coupled in a rotationally fixed manner, and an axle A2 of the spindle arrangement, including a screw gear which is coupled in a rotationally fixed manner to the drive nut, define under a deflection of 90 a single wheel gearbox stage of the parking brake actuator.

A bracket assembly for a brake assembly and a brake actuator includes a tube configured to receive a camshaft of the brake assembly. A brake spider mounting flange and actuator mounting arm are disposed proximate opposite ends of the tube and configured for coupling to a brake spider and the actuator. The arm has inboard and outboard memberseach with a body having one end affixed to the tube and an actuator mounting flange extending from another end of the body. The mounting flanges define aligned bores configured to receive a fastener of the actuator. A centerline of a gusset joining the body and flange of the inboard member is angled relative to at least one of a plane containing a longitudinal axis of the tube and a plane containing a load path line joining the center points of a tube bore and pushrod notch formed in the inboard member.

A brake assembly having a brake spider that may receive an anchor pin or a sleeve that receives an anchor pin. Features such as splines may be provided with the anchor pin to help secure the anchor pin to the brake spider or the sleeve. Engagement features may be provided with the sleeve to help secure the sleeve to the brake spider.
