摘要： An automotive vehicle drum brake including a brake drum for connected to the vehicle wheel and a backing plate for connected to the vehicle. At least one brake shoe is and pivotally mounted with respect to the backing plate. A non-rotative nut mounted for linear motion with respect to said backing plate and has a pivotal connection with the brake shoe. A power screw is threadably engaged with the nut. An electric motor powers the power screw to turn the same to actuate the brakes. A parking brake mechanism is also provided by a coil spring which surrounds a drum which is connected with the power train from and including the electrical motor and the power screw. An actuator is provided to move the coil spring to an unwound position to allow the parking brake to release.
