Ford Model T
The three pedals on the floor of the Model T were for the brake on the right, reverse in the middle to make the Model T go backwards, and a pedal on the left to shift the gears from low to high speed. A lever on the floor worked the brakes as well as the clutch.  Pulling the lever toward the driver would set the parking brake and help keep the car from moving while parked. When the lever was placed in the middle, the transmission would be in neutral.
