(1) The service brakes shall act on all wheels upon application and shall be capable of stopping the vehicle in not more than the maximum stopping distance prescribed in Table I (relating to brake performance).

(2) The service brake system shall act upon all wheels according to the vehicle manufacturer's specifications, except on a vehicle being towed in driveaway-towaway operation or side cars not originally equipped.

(4) The service brake system shall be of a design that rupture or failure of either the front or rear brake system will not result in the complete loss of braking function. Braking function may be obtained by hydraulic or other means through a normal brake mechanism. In the event of a rupture or failure of actuating force component, the unaffected brakes shall be capable of applying adequate braking force to vehicle.

(5) Metal from the shoe or caliper may not contact brake drums or rotors.
