Abstract
An improved electromechanically drivable spreader unit having an integrated adjustment apparatus for a drum brake, in which the linear motion of brake shoe holders is produced by two ball-ramp devices, wherein a first ball-ramp device includes a first actuation piston arranged for rotation about the axis and a second ball-ramp device includes a second actuation piston arranged for rotation about the axis, and wherein an adjustment apparatus for compensating an actuation travel that increases as a result of wear on the friction linings is arranged in an axially centered position within the housing and substantially between the actuation pistons.
