A clutch assembly for a transmission of an agricultural work vehicle. The clutch assembly includes a housing, a clutch pack located within the housing, a piston chamber located within the housing, and a piston located within and slidable relative to the piston chamber. The piston is operably connected to the clutch pack for engaging and disengaging the clutch pack. The clutch assembly further includes a balance chamber that is located within the housing. The lower boundary wall of the balance chamber and the lower boundary wall of the piston chamber are radially separated from one another by a substantial distance.

Provided is a hydraulic unit of a brake system including a housing; an oil supply part configured to supply oil to the housing; an oil discharge part configured to discharge the oil, supplied to the housing through the oil supply part, to the outside of the housing; and a piston movably mounted on the housing, and configured to open and close the oil supply part and the oil discharge part.

Provided is a brake bleeding device for bleeding air accumulated in brake fluid inside a braking device provided in a vehicle. The brake bleeding device includes: a master cylinder constituting a part of the braking device and provided inside a front-side storage chamber, the master cylinder being configured to generate brake hydraulic pressure in accordance with a stroke of an input piston; a brake pedal unit provided inside the front-side storage chamber and configured to give pressing force in a stroke direction to the input piston when a link mechanism connected to the input piston via a rod is operated; and an operating lever attached to the link mechanism in a state where the link mechanism is operable by the operating lever. The operating lever extends downward to a position where the operating lever is accessible from outside the front-side storage chamber.

A hydraulic system bleed system for a vehicle, including a hydraulic system bleed device, including a pneumatic air cylinder containing air in an interior portion thereof, a ram rod disposed at least partially within the pneumatic air cylinder, such that the pneumatic air cylinder and the ram rod are disposed between a steering wheel and a brake pedal of the vehicle, and a recoil spring disposed within the interior portion of the pneumatic air cylinder to provide a springing reciprocating movement for the ram rod, and a mobile device to provide a signal to the hydraulic system bleed device to initiate the reciprocating movement such that the brake pedal is depressed.

A hydraulic device comprises a hydraulic structure and a release member. The hydraulic structure includes an interior space in which a fluid is to be filled. The release member is attached to the hydraulic structure so as to be exposed to the interior space and an atmosphere. The release member is configured to release air from the interior space toward the atmosphere in accordance with an internal pressure of the interior space.

A hydraulic system bleed system for a vehicle, including a hydraulic system bleed device, including a pneumatic air cylinder containing air in an interior portion thereof, a ram rod disposed at least partially within the pneumatic air cylinder, such that the pneumatic air cylinder and the ram rod are disposed between a steering wheel and a brake pedal of the vehicle, and a recoil spring disposed within the interior portion of the pneumatic air cylinder to provide a springing reciprocating movement for the ram rod, and a mobile device to provide a signal to the hydraulic system bleed device to initiate the reciprocating movement such that the brake pedal is depressed.

This caliper body includes a cylinder portion (26) that has a piston disposed therein and is internally provided with a liquid pressure chamber, a bleeder boss portion (29) that communicates with the liquid pressure chamber and includes a bleeder hole configured to discharge air from the liquid pressure chamber, and a plurality of identifiers (112 and 116). At least one identifier (112) of the identifier (112 and 116) is formed in a region hidden by a bleeder plug (131) attached to the bleeder boss portion (29).

A ratcheting brake bleeder wrench is provided which sealingly couples to a bleed valve. The brake bleeder wrench has an internal fluid passageway which allows egress of fluid from a hydraulic brake system. The ratcheting brake bleeder wrench is used to open the bleed valve, allowing egress of fluid, remains in place during the bleeding operation, and reverses direction upon completion of bleeding to tighten the bleed valve back into sealing relationship with the hydraulic brake system.

Provided is a front vehicle body structure of a vehicle equipped with a vehicle brake system including an electric brake actuator that generates a brake hydraulic pressure based on at least a brake pedal operation and a reservoir tank for a brake fluid, the electric brake actuator and the reservoir tank being disposed to be spaced apart from each other in a mounting compartment for a power unit defined in front of a dashboard. The electric brake actuator is eccentrically disposed in the mounting compartment on the left or right side of the vehicle.

A fixing point for fixing a piping tube connecting the electric brake actuator and the reservoir tank is provided on a junction box inside the mounting compartment.

A brake caliper and a vehicle having the same are provided. The brake caliper includes: a caliper body and an exhaust screw. A brake disc groove and a piston cylinder are constructed in the caliper body. A brake-fluid delivery oil line and an exhaust channel are constructed in a wall of the caliper body. The brake-fluid delivery oil line is in communication with the piston cylinder. The exhaust channel is in communication with an end of the brake-fluid delivery oil line in a length direction of the caliper body. An exhaust port is provided on a side of the caliper body in a thickness direction, and the exhaust port is in communication with the exhaust channel. An exhaust screw is mounted on the exhaust port on the side of the caliper body, to control opening or closing of the exhaust port.
