1. A brake pedal assembly comprising:
a pedal; and
a pedal resistance force member operably coupled to the pedal and including:
a damper pedal resistance force module defining an interior fluid-filled cavity;
a shaft extending through the damper module and including a piston mounted thereon and moveable through the fluid-filled cavity to generate a damper resistance force;
a spring pedal resistance force module adapted to generate a spring pedal resistance force;
a pedal force sensing module mounted to the pedal resistance force member;
a pedal position sensor mounted to the pedal resistance force member;
a pedal force sensor mounted to the pedal resistance force member, and
the pedal resistance force member including a moveable sleeve and a fixed sleeve, the moveable sleeve moving in response to the movement of the pedal, the shaft being operably coupled to the moveable sleeve and moveable in response to the movement of the moveable sleeve, the spring pedal resistance force module being coupled to the fixed sleeve and including first and second springs compressible in response to movement and contact with the shaft and the fixed sleeve respectively for generating the spring pedal resistance force,
wherein the pedal force sensing module is coupled to the moveable sleeve, and
wherein the spring pedal resistance force module and the pedal force sensing module are located at opposed ends of the pedal resistance force member.
