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 disc brake includes: an inner pad and an outer pad respectively located on opposite sides of a rotor; a pressing device that presses the inner pad and the outer pad against the rotor; and a housing holding the pressing device. The pressing device includes: at least one first pressing member movable toward the rotor and at least one second pressing member movable away from the rotor; and a driving member movable relative to the housing in an axial direction parallel with a rotation axis of the rotor and configured to be moved by movement of the at least one second pressing member to press the outer pad against the rotor. The housing is provided with a torque receiver that receives torque acting on the outer pad in operation of the disc brake.

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.

A disc brake caliper body adapted to be arranged straddling a brake disc. The caliper body includes at least one elongated element connecting bridge which connects a first wheel side elongated element to a second wheel opposite side elongated element adapted to be arranged straddling the brake disc. The caliper body includes at least one air conveying channel which extends longitudinally as a connecting bridge which connects the first wheel side elongated element to said second wheel opposite side elongated element so as to be adapted to be arranged straddling the brake disc. The disc outlet channel side includes a disc outlet channel side portion free edge, a channel bottom includes a channel bottom portion free edge, a disc inlet channel side free edge, a disc outlet channel side portion free edge and a channel bottom portion free edge defining a cooling air collection and conveying inlet.

A method for actuating a parking brake system of a vehicle with at least three brake calipers associated with one or more axles of the vehicle is described. The method may include the following steps: providing at least one detection device for detecting the vehicle status, acquiring a value of the vehicle status with the detection device, comparing the detected value with a reference value of the vehicle status, and actuating two brake calipers of the at least three brake calipers if the detected value is lower than the reference value or actuating all the at least three brake calipers if the detected value is equal to or greater than the reference value.

A disc brake of a floating type includes: an inner pad and an outer pad respectively located on opposite sides of a rotor; a pressing device that presses the inner pad and the outer pad against the rotor; and a housing mounted on a non-rotating member and holding the pressing device. The pressing device includes: first pressing members movable toward the rotor, and at least one second pressing member movable away from the rotor; and a frame held on the housing so as to be movable relative to the housing in an axial direction that is a direction parallel with a rotation axis of the rotor. The frame moves in response to movement of the at least one second pressing member to press the outer pad against the rotor.

A brake caliper (100) with first and second parts (104a, 104b) between which is received a pair of braking members (102a, 102b). The caliper (100) includes a service brake mechanism having at least two piston and cylinder assemblies (108a, 110a and 108b, 110b) forming an opposed piston mechanism for forcing each of the braking members (102a, 102b) towards a brake disc to apply a service braking force thereto. The caliper (100) also includes a park brake mechanism including an actuator mechanism (112) for applying a driving force to a first opposed braking member (102a) towards the brake disc and a force transmitting member (116) for transmitting the driving force to a second opposed braking member (102b). The force transmitting member (116) is supported by a sliding connection between the force transmitting member (116) and an outer surface of a first cylinder (110a) and a slidable connection between the force transmitting member (116) and a connecting member that spans the first and second parts of the brake caliper (100).

A caliper comprising: (a) an inboard side; (b) an outward side, wherein the inboard side and the outboard side include three or more bores that are radially staggered relative to two or more of the bores; and (c) a pocket located within a central region of the inboard side, the outboard side, or both; wherein the bores on the inboard side, the outboard side, or both are positioned so that: (i) all of the bores are located entirely radially below the pocket; (ii) none of the bores are located below the pocket; (iii) one or more of the bores are located partially radially below the pocket; (iv) one or more of the bores are located entirely radially below the pocket; (v) one or more of the bores are not located partially or entirely radially below the pocket; or (vi) a combination of (iii) through (v).

An electric parking brake for an automotive vehicle comprises a brake caliper having first and second bores. A first piston is mounted in the first bore and a second piston is mounted in the second bore. A first actuator supports the first piston and a second actuator supports the second piston. The first and second actuators are controlled individually.

A service brake caliper and the parking brake caliper (hereinafter called P caliper) are supported by a swing arm rotatably supporting the rear wheel. The service brake caliper and the P caliper are configured to brake the brake disc. In the rear brake device of the vehicle, the service brake caliper and the P caliper are fixed to a stay member, the stay member being supported by the swing arm. At least some of the service brake caliper and the P caliper are arranged in positions forward of a vehicle body and upward of the vehicle body from an axle of the rear wheel. A first boss and a third boss are arranged on a straight line passing through a center point of the axle.
