ELECTROMECHANICAL BRAKE SYSTEM AND METHOD OF OPERATION

The invention relates to an electromechanical brake system comprising a brake actuator (2) having a power transmission means for transmitting an actuating force to a brake pad, said power transmission means including a rotatable shaft (81), a coupling means with a locking element (35), wherein the coupling means can be controlled so that the locking element (35) is engaged with the rotatable shaft (81) and blocks its rotation or so that the locking element (35) is disengaged from the rotatable shaft (81) so that the rotatable shaft (81) can be rotated, wherein the brake actuator (2) comprises an interface (31) configured to be connected to the locking element (35) and to engage or disengage the locking element (35) from the rotatable shaft (81).
