A disc brake includes: an inner pad and an outer pad; a pressing device configured to press the inner pad and the outer pad against a rotor, the pressing device including a first presser member and a second presser member that are movable parallel to a rotational axis of the rotor, and a frame that is a frame-shaped rigid body and is movable in the direction parallel to the rotational axis; and a housing mounted on a non-rotating body, the housing holding the pressing device, the housing including a pad pin that hold the inner pad and the outer pad so as to be movable in the direction parallel to the rotational axis, the pad pin being held by the housing at both ends of the pad pin in the direction parallel to the rotational axis.

A method and apparatus for monitoring the condition of a service brake for a vehicle is provided. The service brake includes at least one linear path detection device for each service brake unit. The method includes reading a position signal of a service brake component from the path detection device over time or a time period, reading a pressure signal, a control signal and/or a lining wear signal, evaluating the position signal in order to determine at least one condition parameter of the service brake determined using the pressure signal, the control signal and/or the lining wear signal, and providing the condition parameter of the service brake to an interface for use in subsequent brake applications.

For rapid and precise actuation of a friction brake, the thermal expansion of the friction brake is determined using a thermal model of the friction brake and therefrom the temperature-dependent shift in the contact point is determined for the braking operation and the temperature-dependent shift in the contact point is taken into account when determining the actuation measure of the friction brake to be adjusted.

An S-cam brake includes an S-cam unit for braking a drum, where the S-cam unit includes an S-cam of an S shape having an involute tooth profile at left and right sides thereof, and horizontal tangential members forming contacting surfaces engaged with the involute tooth profile symmetrically around a center point of a circle at the left and right sides of the S-cam, and being spread at the left and right sides with normal lines of the contacting surfaces as a horizontal direction when the S-cam rotates.

A disc brake and an adjuster system for a disc brake. The adjuster system may include a piston, a chamber, and a wear adjustment mechanism. The wear adjustment mechanism may be located within the chamber. The chamber may contain lubricant for lubrication of at least part of the wear adjustment mechanism.

An electric parking brake for a vehicle brake system includes a caliper, a piston, a spindle, an adjuster nut, a ring-like member affixed to the piston, and a biasing member. The piston may be disposed within a cavity of the caliper. The spindle is configured to drive the axial movement of the adjuster nut between a retracted position and an extended position via a threaded engagement wherein the adjuster nut is disposed within the piston. The biasing member may be disposed between the ring-like member and the adjuster nut so that, as the adjuster nut moves from an extended position to a retracted position which corresponds to a control signal, the biasing member urges the piston away from the rotor.
