A wet brake includes a housing, non-rotatable brake discs, rotatable brake discs, a parking lever, a piston, a plate, and a connector. The non-rotatable and the rotatable brake discs are disposed in engagement with the housing and an outer peripheral surface of a rotary shaft, respectively. The piston, the plate, and the rotary shaft are accommodated in the housing. The piston is configured to be pushed by the parking lever toward the non-rotatable and the rotatable brake discs. The plate is in contact with one of the non-rotatable brake discs or one of the rotatable brake discs. The connector is disposed at a position between the piston and the plate. The housing has a recess that is formed in an outer peripheral surface of the housing at a position corresponding to the position of the connector. An outer diameter of the connector is smaller than that of the piston.

A braking system for a vehicle, includes: a rotatory braking element that is fixedly connected to a wheel or wheel axle in a manner to rotate conjointly with the wheel having a rotational plane, a stationary braking element that is fixedly connected relative to a vehicle chassis so as not to rotate conjointly with the wheel, a first brake actuator that is configured to actuate the stationary braking element so as to urge the stationary braking element towards the rotatory braking element, a second brake actuator that is configured to actuate the stationary braking element so as to urge the stationary braking element towards the rotatory braking element, and a lever that is configured such that it transfers a force exerted by the first brake actuator or the second brake actuator to the stationary brake element. The first brake actuator is connected to the lever via a first connection portion and the second brake actuator is connected to the lever via a second connection portion such that the second brake actuator operates decoupled from the first brake actuator when the second brake actuator is actuated.
