A brake assembly for a servo including a motor includes: a brake disk fixed to and rotatable together with the output shaft of the motor of the servo, the brake disk having a lateral wall defining at least one opening; and a linear motion actuator including a plunger and an elastic member. The plunger sides from a first position where a first end of the plunger is received in the at least one opening to a second position where the first end of the plunger is disengaged from the brake disk when the linear motion actuator is energized. The elastic member applies an elastic force to cause the plunger to slide from the second position to the first position when the linear motion actuator is deenergized so as to stop rotation of the output shaft of the motor.

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 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.

Disclosed are a parking actuator and an electromechanical brake including the same. The parking actuator, which is connected to a brake actuator that performs braking of a vehicle, includes a parking gear connected to the brake actuator to be rotatable together, a parking lever having one side hingedly fixed and the other side engaged with the parking gear, a parking motor provided to generate power, a power conversion unit including a spindle member rotating by receiving a rotational driving force of the parking motor and a nut member screwed to the spindle member to move forward or backward, and a pressing unit installed on the nut member to press the parking lever by the nut member moved forward or backward.

System for suctioning braking particles from a friction braking system, the suction system including a negative-pressure source, a suction mouth, a pneumatic circuit connecting the suction mouth and the negative-pressure source, and a control unit, the suction system further including a closure unit arranged on the pneumatic circuit, the closure unit being able to isolate at least a first portion of the pneumatic circuit, the control unit being configured to control the closure means according to a predetermined logic in order to isolate the first portion of the pneumatic circuit during certain phases between two actual uses of the negative-pressure source.

A brake control device is configured such that a hydraulic braking device is provided for one of a front wheel and a rear wheel, and an electric braking device is provided for the other one of them. The electric braking device is provided with a mechanism configured to prohibit retreat of a piston for pressing friction members against a rotor that rotates with the wheel. The brake control device is configured to maintain, by an operation of the mechanism, a braking force that does not depend on a force of an electric motor as a drive force and to control a braking force generated by the hydraulic braking device based on a difference between the braking force thus maintained and a braking force requested for the electric braking device.

A system for braking a trailer pulled by a vehicle. A trailer braking system is provided on a trailer. An electrically actuated linear actuator of the trailer braking system is coupled to the braking system of the pulling vehicle. The linear actuator is coupled to a lever that, upon actuation of the vehicle brake, actuates a piston to push brake pads into a rotor coupled a wheel on the trailer. A wheel speed monitor reduces braking force of the trailer braking system in response to a predetermined change in wheel speed. An anti-lock braking system reduces trailer wheel skid under braking. Multiple trailer braking systems can be applied to multiple wheels on the trailer to provide more or less braking.

A brake assembly comprising: (a) a caliper including: (i) one or more pistons, (b) one or more rotary to linear actuators that provides an axial force to move the one or more pistons, (c) a motor gear unit in communication with the one or more rotary to linear actuators, the motor gear unit including: (i) a motor; and (b) a motor brake that prevents movement of the motor gear unit, the pistons, or both when the motor is turned off so that a brake apply is maintained, the motor brake including: (i) housing; (ii) an engaging element; (iii) a sleeve, and (iv) a solenoid that is in communication with the sleeve so that when the solenoid moves the sleeve, the engaging element is moved into contact with the housing creating a braking force.

An electromechanical brake system includes a caliper, an electric motor mounted to the caliper, a gear element mechanically connected to the electric motor, an actuator supported by the caliper, the actuator including an actuation member, and a controller operatively connected to the actuator. The controller is operable to selectively engage the actuation member with the gear element to positionally lock the first caliper member relative to the second caliper member.

An object of the invention is to provide a disc brake improved in reliability. In a disc brake, a first holder-side projection is formed on a holder, and a first cover-side recess that fits the first holder-side projection of the holder is formed in a cover. An elastic member is disposed between the first holder-side projection of the holder and the first cover-side recess in the cover.
