Scott--The Early Maxwell's without planetary transmissions used a single pedal for both clutch and brake. Push the pedal down half way, it would disengage the clutch; push it all the way, it applies the brake. The parking brake was similarly arranged. Often, as on my 1912 Mascotte, owners would separate the two functions and add a brake pedal.
