Abstract
A variable ratio brake pedal mechanism providing a relatively short pedal stroke. A projection on a pivoted pedal lever bears on a second oppositely pivoted lever, providing conjoint movement of the two levers. A push rod brake actuator is pivotally connected to the second lever. The push rod and a portion of the second lever jointly form a toggle linkage which decreases the ratio of movement of the brake actuator relative to the pedal lever, and increases the mechanical advantage, as brake application occurs.
