Method for adjusting the slack of a brake assembly and brake assembly

A brake assembly, comprising:

• a brake disc in rotational engagement with a wheel of a vehicle;
• a brake pad which frictionally engages said brake disc when an actuator force is applied thereto;
• an actuator having an output shaft driven in a forward direction to bring the brake pad and brake disc in said frictional engagement defining a braking position, and a reverse direction to disengage the brake pad and brake disc and to move the brake pad into a rest position, wherein in the rest position the brake pad and the brake disc are frictionally disengaged;
• a slack adjuster adjusting a predetermined axial slack distance between the brake pad and the brake disc in the rest position of the brake pad, wherein the slack adjuster is configured such that, for initiating the adjustment procedure, the brake pad is moved by the actuator in the reverse direction into a predetermined reference position.
