Abstract
An adjustable automotive pedal system includes a parallel bar suspension system for a foot pedal assembly system, such that the foot pedal can be adjusted toward the driver seat or away from the driver seat without adversely changing the force-stroke relationship between the foot pedal and the component being controlled by the foot pedal. The pedal system can be used with the vehicle brake, or vehicle clutch, or accelerator linkage.
