Subchapter I. Equipment Requirements
§ 4303. Brakes — General requirements.

(a) Every motor vehicle when operated upon a highway shall be equipped with brakes adequate to control the movement of and to stop and to hold such vehicle and any trailer or semitrailer attached thereto including 2 separate means of applying the brakes, each of which means shall be effective to apply the brakes to at least 2 wheels and shall be so constructed that no part which is liable to failure shall be common to the 2. A motorcycle need be equipped with only 1 brake. All brakes shall be maintained in good working order and shall conform to regulations, not inconsistent with this subchapter, to be promulgated by the Secretary. All brakes shall be so adjusted as to operate as equally as practicable with respect to the wheels on opposite sides of the vehicle.
(b) All braking distances specified in this subchapter shall apply to all vehicles mentioned herein, whether such vehicles are loaded or are not loaded to the maximum capacity permitted under Chapter 45 of this title.
(c) Except as provided in this subsection, no motor vehicle, when operated upon a highway in this State, shall utilize or employ any brake or braking system that is attached to, or an integral part of, the vehicle's internal combustion engine or exhaust systems. Nothing in this section shall be interpreted as prohibiting the equipping of any motor vehicle with a braking system that is attached to, or an integral part of, the vehicle's engine or exhaust systems. Nothing in this section shall be interpreted as prohibiting the use of a braking system that is attached to, or an integral part of, the vehicle's engine or exhaust system in an emergency situation or an emergency vehicle including police, fire, ambulance, emergency medical service vehicles or other emergency vehicles.
