ABSTRACT:
The variable pedal ratio brake actuating mechanism has a first lever pivotally mounted on an arcuately movable brake pedal arm. The lever is guided pivotally by a pivot control lever which pivots about a fixed point at one end and is connected at its other end to a first pivot on the first lever spaced from the first lever pivotal mount. An output member is pivotally connected to a second pivot on the first lever spaced from the first lever pivot mount and first pivot. The first lever is moved translatorily and also arcuately about its pivotal mount as the brake pedal arm moves in the brake actuating direction to change the effective pedal ratio.
