Abstract
A brake mechanism for a motor assembly including a motor and a reduction gear assembly driving an output shaft or axle is disclosed. A brake rotor is driven by the motor shaft and a brake puck is operatively engageable with the brake rotor for moving the brake rotor toward a braking surface. A brake cam shaft is rotatably supported about an axis perpendicular to the axis of the output shaft and engages the brake puck so that rotation of the brake cam shaft about its axis forces the brake puck to move the brake rotor toward the braking surface.
