This SAE Recommended Practice presents service brake performance requirements for the brake systems of motor vehicles intended for roadway use and falling in the following classifications: Light Truck (10,000 lb gvw or less—Uniform Vehicle Code—Class B-2). Truck and Bus (over 10,000 lb gvw—Uniform Vehicle Code—Class C-1 and C-3). Combination of Vehicles (Uniform Vehicle Code—Class D). Acceptable performance requirements are based on data obtained from applicable sections of SAE J786.

This SAE Recommended Practice provides a test method and instructions for measuring performance of parking brakes on air- or hydraulic-braked vehicles equipped with in-wheel or drive-line parking brakes. This procedure applies to truck-tractors, trailers, trucks, and buses.

Subject document is specifically intended for service brakes and service brakes when used for parking and/or emergency brakes (only) that are commonly used for automotive-type, ground-wheeled vehicles exceeding 4536 kg (10000 pounds) gross vehicle weight rating (GVWR). Subject specification provides the off-vehicle procedures, methods, and processes used to objectively determine suitability of tactical and combat ground-wheeled vehicle brake systems and selected secondary-item brake components (aka, aftermarket or spare parts), including brake “block” for commercial applications only, specifically identified within subject document. Subject specification is primarily based on known industry and military test standards utilizing brake inertia dynamometers.
