Abstract

A parking brake actuation assembly is provided including an electric motor and a first rotatable member operatively connected to the electric motor so as to enable the motor to rotate the first rotatable member in a brake applying rotational direction. The first rotatable member normally is prevented against rotation in a brake releasing rotational direction. A second rotatable member is rotatable relative to the first rotatable member and includes cable attachment structure for affixing a brake activation linkage thereto. A clutch spring is disposed between the first and second rotatable members and is configured to contract upon initiation of rotation of the first rotatable member in the brake applying direction so as to couple the second rotatable member to the first rotatable member for affecting rotation of the second rotatable member in the brake applying direction.
