PURPOSE: A hydraulic brake is provided to increase the torque capacity of the brake by using the piston unit comprising two pistons within the limited space. CONSTITUTION: A cylinder(230) is formed in a transmission case. A piston unit(220) is installed within the cylinder. The piston unit operates by the operation fluid pressure. An operation plate(260) is pressurized by the operation of the piston unit in axial direction. A friction disc(270) is pressurized as being arranged along with the operation plates alternately. |
