The present invention relates to a brake actuation unit comprising a cylinder/piston arrangement which acts on at least one brake lining which can be brought into frictional engagement with a brake disk, a hydraulic pump which is hydraulically connectable with a pressure chamber of the cylinder/piston arrangement in order to move the cylinder of the cylinder/piston arrangement relative to the piston of the cylinder/piston arrangement, and a motor for driving the hydraulic pump.

[ We claim:] [1.]1. A brake actuation unit comprising:a cylinder/piston arrangement having a cylinder, a piston, and a pressure chamber;a brake lining acted upon by the cylinder/piston arrangement, which brake lining is disposed to be brought into frictional engagement with a brake disk in response to pressure in the pressure chamber;a hydraulic pump which is hydraulically connectable with the pressure chamber of the cylinder/piston arrangement in order to move the cylinder of the cylinder/piston arrangement relative to the piston of the cylinder/piston arrangement by selectively varying the pressure in the pressure chamber to move the brake lining relative to the brake disk, characterized in that the hydraulic pump is an axial piston pump which is an inclined disk machine where a supporting disk is stationary and a cylinder drum is rotatable, with at least one pump piston being slidably accommodated within the cylinder drum, with the pump piston performing a reciprocating movement which is positively controlled by the supporting disk when the cylinder drum rotates; anda motor for driving the hydraulic pump, wherein the hydraulic pump is selectively operable in a pressure build-up, a pressure holding and a pressure relief position to selectively vary the pressure in the pressure chamber.
