Abstract: During an operation of applying a parking brake, when sufficient brake clamping force is applied by a brake actuator, a parking lock actuator having a pin is energized to cause the pin to be moved toward a strut so that the strut is engaged with one of notches of a rotatable part operably connected with the brake actuator in order to prevent rotation of the rotatable part in one direction of releasing the brake and to allow rotation of the rotatable part in the other direction of applying the brake, and then the parking lock actuator is de-energized and the pin is moved away from the strut. During an operation of releasing the parking brake, the brake actuator rotates the rotatable part in the brake apply direction to disengage the strut from the notch, and then releases the brake.

Abstract: A boot assembly for a vehicle brake comprises: a flexible boot having an end portion coupled to a housing accommodating at least some components of the vehicle brake including a rotatable body configured to be rotatable by an actuator to move a brake pad and a bearing configured to rotatably support the rotatable body and comprising a non-rotatable bearing race, wherein the boot supports the non-rotatable bearing race; and a boot retainer configured to hold the boot in a fixed position with respect to the housing. Another end portion of the boot is coupled to a linearly movable body configured to be translatable according to rotation of the rotatable body of the vehicle brake to seal an inner bore of the housing. The boot is coupled with one side of the non-rotatable bearing race to limit an axial movement of the non-rotatable bearing race away from the housing.

Abstract: An internal type electronically controlled valve assembly includes a main poppet retainer formed in a disc shape with a rim protruding downward and disposed horizontally between a main poppet and a control disk. The internal type electronically controlled valve assembly is configured such that, during a compression stroke, a working fluid introduced through a hollow hole of a main sheet passes between the control disk and the main poppet retainer, reducing the pressure, and then flows into a pilot passage formed in the main poppet, thereby significantly reducing the pressure of a compression pilot chamber.
