An electric parking brake actuator mounting assembly includes a brake backplate of a drum brake, having a rear surface opposite to a front surface configured to be facing a brake drum when the brake backplate is mounted on a motor vehicle, wherein the rear surface of the brake backplate includes a support base configured to receive a pull spindle of an electromechanical actuator, a supporting bracket including at least one coupling plate, configured to be attached to the rear surface of the brake backplate, and an actuator mounting surface configured to be coupled to and support the electromechanical actuator, wherein the actuator mounting surface includes a spindle seat, configured to receive the pull spindle of the electromechanical actuator, and a pin lock seat, configured to receive and lock an engagement pin of the electromechanical actuator.

An electronic braking arrangement includes a brake stack assembly, a driver circuit, a current limiter circuit, and a voltage limiter circuit. The driver circuit is operably connected to the brake stack assembly. The current limiter circuit and the voltage limiter circuit are connected in series between the driver circuit and the brake stack assembly to drive friction brake loads in the brake stack assembly with a voltage limited constant drive current.

A power split hybrid powertrain includes an electrically actuated brake that selectively engages a ring gear attached to a flywheel. The ring gear may be, for example, a starter ring gear. Engagement of the brake while the engine is stopped permits use of both electric machines to provide torque to vehicle wheels, thereby increasing the electric torque capacity of the powertrain. The brake is mounted for movement relative to the ring gear, and a mechanical linkage is attached to the brake. In the event of a malfunction of the brake that prevents normal operation of the powertrain, the linkage is manually actuatable by a vehicle operator to move the brake to an override position wherein it cannot engage the ring gear.
