1. A friction brake for a vehicle power shift transmission, comprising:
a load gear that is rotatably driveable about a centre longitudinal axis;
a friction braking device for decelerating and/or fixing the load gear;
an actuating device for actuating the friction braking device, the actuating device includes an moveable spreading piston;
wherein the moveable spreading piston while performing a spread along the centre longitudinal axis automatically materialising as a function of a load torque provided on the load gear, provides a braking force for actuating the friction braking device.
