Electromechanical brake system including a force application apparatus

An electromechanical brake system, comprising:

• a housing defining a mechanism cavity;
• an apparatus for force application having first and second pistons is located at least partially within the mechanism cavity;
• and
• a brake pad, operatively connected to both the first and second pistons for longitudinal driving thereby;
• the apparatus for force application including
• the first piston, including a first piston motivator comprising a first push rod and an actuator, the first piston being configured for selective longitudinal travel;
• the second piston, spaced laterally from the first piston, the second piston being configured for selective longitudinal travel;
• a rocker arm, operatively connected to both the first and second pistons for force transmission therebetween, and
• a pivot bearing, rotatably supporting the rocker arm;
• wherein the actuator is configured to move selectively longitudinally with respect to the first push rod to move at least a portion of the first piston toward the brake pad, the pivot bearing is maintained in a predetermined longitudinal position as a reaction force is developed between the first piston and the brake pad, and the rocker arm transmits at least a portion of the reaction force from the first push rod to the second piston.
