A brake assembly includes a brake disc in rotational engagement with a wheel of a vehicle, a brake pad which frictionally engages the brake disc in a dynamic braking operation and a parking brake operation, a dynamic actuator adapted to bring the brake pad and brake disc into the frictional engagement in the dynamic braking operation, and a parking brake actuator associated with the dynamic actuator such that, in the parking brake operation, the frictional engagement of the brake disc and brake pad is maintained.

A motor transmission unit for an electronic parking brake device includes a case, a driving member, a board, a rod and a push unit. The case is slidably mounted to a cap of a clamp. The driving member is partially inserted into the case. The board is threadedly mounted to the driving member. The rod is located between inner periphery of the passage and the board. The push unit has a first end thereof contacting the first end face, and a second end of the push unit is inserted in the clamp. A portion of the second end of the push unit contacts a piston. When the driving member is driven, the board moves axially. The board is restricted by the rod and does not rotate. The board pushes the push unit axially which moves the piston to push a lining plate of the clamp to contact a brake disk.

The disclosure relates to the technical field of vehicle accessories, and in particular to a brake for a vehicle and a vehicle. The disclosure aims at solving the problems present in existing brakes for a vehicle that oil passages are relatively long, an angle at which each oil passage is arranged is relatively large, debris generated in a machining process remains in the oil passages and then causes blockage of the oil passages, and drilling holes in an inner caliper body and an outer caliper body to form the oil passages further reduces mechanical strength of the inner caliper body and the outer caliper body. For this purpose, the brake for a vehicle according to the disclosure comprises a first caliper body and a second caliper body, wherein the first caliper body is fixedly connected to the second caliper body, the first caliper body and the second caliper body are each provided with a piston chamber, a piston is arranged in each piston chamber, the first caliper body is provided with a first oil passage penetrating through the piston chamber in the first caliper body, the second caliper body is provided with a second oil passage penetrating through the piston chamber in the second caliper body, and the first oil passage fluidly connects with the second oil passage by means of a hard oil pipe. The foregoing arrangement can simplify oil passage pathways in the first caliper body and the second caliper body.

A disc brake caliper has a caliper body and a pair of pads and, in each side portion of the caliper body, a distal piston and a proximal piston, having radially distanced and aligned pressure centers.

Land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.

A caliper body for a disc brake having at least one thrust housing. The housing has a housing bottom wall and a housing lead-in edge portion. The housing lead-in edge portion has at least one housing edge surface. At least either a first elongated element caliper inner side or a second elongated element caliper inner side has at least one groove bottom wall and groove sides which delimit at least one groove. The at least one groove bottom wall is axially outer with respect to the housing edge surface.

A caliper body has a first elongated element facing a first braking surface. The first elongated element has first and second ends. The caliper body has a second elongated element facing a second braking surface. The first elongated element has first and second ends of second elongated element. The first ends of first and second elongated elements face each other. The second ends of first and second elongated elements face each other. The first ends of first and second elongated elements are connected by a first end bridge. The second ends of first and second elongated elements are connected by a second end bridge. The first and second elongated elements are connected by a central bridge. The first or second elongated element has two connecting housings for connection to a support for the caliper body in a vehicle.

A method of controlling a brake system that includes a motor and an actuator. The method includes moving the actuator towards a retracted position; activating a timer; monitoring a motor characteristic of the motor and monitoring the timer; and determining the actuator has reached the retracted position after the timer meets or exceeds a predetermined time threshold before the motor characteristic has reached or exceeded a predetermined motor characteristic threshold.

A brake system for a piece of equipment includes a series of rotors and stators, and a first brake actuator including at least one first piston positioned within a first chamber such that pressurization of the first chamber causes the at least one first piston to operatively engage at least one of rotors or stators such that the rotors and stators are compressed together and thereby create braking torque, and may also include a second brake actuator including at least one spring operatively coupled to at least one second piston positioned within a second chamber such that depressurization of the second chamber causes the at least one second piston to operatively engage at least one of the rotors or stators such that the pluralities of rotors and stators are compressed together and thereby create braking torque.

A method that includes monitoring a motor characteristic; and determining an actuator of a brake system has reached a retracted position after the motor characteristic has reached or exceeded a predetermined threshold.
