Abstract
An electric drive for a parking brake is disclosed, the brake having a rotationally driven screw nut which is in engagement with two spindles which are aligned with one another, have threads running in opposite directions, and which are fixed in the rotational direction, can be moved in a translatory fashion and are each provided with a cable holder for connecting to brake elements. Here, one of the two spindles is a hollow spindle whose internal diameter is greater than the external diameter of the other spindle so that when the screw nut rotates, the spindle on one side can be retracted in a telescopic fashion into the hollow spindle on the other side.
