ABSTRACT:
A vehicle disc brake is provided which, in a preferred embodiment, includes a first caliper pivotally mounted with respect to the vehicle, a first brake shoe slidably mounted with respect to the first caliper for selective contact with a vehicle wheel rotor, an electric actuator to selectively move the first shoe into engagement with the rotor, an actuator plate mounted for relative motion with respect to the vehicle and operatively associated with the first caliper wherein movement of the first caliper resultant of the first shoe engagement with the rotor causes the actuator plate to move, a second caliper generally locationally fixed with respect to the vehicle wheel axis, a second brake shoe mounted by the second caliper operatively associated with the actuator plate for engagement with the rotor, and a ball captured in a ramp between the actuator plate and second brake shoe for converting movement of the actuator plate into movement of the second brake shoe to engage with the rotor.
