An electro-mechanical brake and a vehicle including the same are provided. As an electro-mechanical brake according to one embodiment of the present invention, an electro-mechanical brake including a drum, a first brake shoe, and a second brake shoe, may include a motor that provides a rotational driving force; a rotating member that rotates about a second rotating shaft perpendicular to a first rotating shaft of the motor; a power transmission member that transmits the rotational driving force of the motor to the rotating member; and a rotating screw that is coupled to the rotating member so that the first brake shoe is able to move forward and backward toward one inner peripheral surface of the drum.

A braking system is presented that comprises a brake sphere rotor that is mounted to the wheel hub of an axle. The braking system incorporates a caliper arm assembly that comprises at least one caliper arm. Each caliper arm further comprises hemispherical friction material located between the caliper arm and the brake sphere rotor.

An electric parking brake device includes: a “linear motion member configured to be driven by an electric motor, moved in a forward direction so as to apply a parking brake and moved in a backward direction opposite to the forward direction so as to release the parking brake”; and a “controller configured to control the electric motor”. When the parking brake is released, the controller stops energization to the electric motor at a time point when a first predetermined time elapses after a time point when an energization amount to the electric motor becomes constant.

A sensor mounting arrangement for a drum brake assembly of a heavy-duty vehicle comprising a sensor assembly mounted on a cam tube of the drum brake assembly. The cam tube is formed with an opening. The sensor assembly includes a detector that is at least partially disposed in or adjacent to the opening of the cam tube and a target that is disposed about an outer surface of a camshaft of the drum brake assembly.

A speed limited rotational member including a first member, a second member rotatable relative to the first member, and first and second brake elements. The first and second brake elements are pivotally mounted to the first member for both pivoting between a first position spaced apart from a cooperating surface of the second member and a second position engaging the cooperating surface of the second member for generating friction to reduce a rotational speed of the rotational member. The speed limited rotational member further includes at least one linkage connecting the first and second brake elements. The speed limited rotational member may optionally include a down pressure component.

Provided is motor-driven drum brake system including: a motor-driven drum brake including a brake shoe inside a drum and allowing the brake shoe to be pressed on an inner surface of the drum by hydraulic pressure of a wheel cylinder or an operation of a motor to perform braking; and a controller configured to control the motor to engage the motor-driven drum brake, wherein the controller is configured to, upon a total count of parking apply operations of the motor-driven drum brake being greater than a preset count when performing a parking apply operation, correct a target clamping force of the motor-driven drum brake and perform the parking apply operation according to the corrected target clamping force.

The present disclosure relates to heavy vehicle drum brakes. In a particular form, the present disclosure relates to a brake shoe configured for ease of changing thereof, and to an apparatus and method for changing drum brake shoes. In one aspect, the brake shoe comprises a lining table supporting a brake lining, and at least one web extending from the lining table, the web comprising a spring attachment aperture extending therethrough, the brake shoe further comprising an access aperture extending through the lining table and the brake lining, wherein a center line of the access aperture intersects, or is at least close to intersecting, a center line of the attachment aperture.
