The minimum performance values in this SAE Recommended Practice are applicable to vehicles with brake systems having typical service pressure ranges 0 to 16.6 MPa (0 to 2400 psi) hydraulic or 0 to 945 kPa (0 to 135 psi) air only. SAE J880 not only provides for determining maximum brake rating power capability, but also permits verification of any desired or arbitrary level such as the requirement established herein. The determining criteria for deciding brake rating power capability are: a. Cold brake stopping ability. b. Fade as a result of brake power absorption. c. Hot brake stopping ability following brake power absorption. d. Brake system stability following brake power absorption. e. Functional and structural integrity of brake system following test.

This SAE Recommended Practice establishes performance guidelines for the threshold pressure and brake force output of the brakes on the axles of air-braked towing trucks, truck-tractors, truck-trailers, and converter dollies with GVWRs over 10 000 lb designed to be used on the highway in combination with other air-braked vehicles of this type in commercial operations.

This SAE Recommended Practice presents performance requirements for the brake systems of motor vehicles intended for roadway use and falling into the following classifications: Light trucks and buses: 6001-10 000 lb (2700-4500 kg) gvw; Truck and bus: Over 10 000 lb (4500 kg) gvw; combination of vehicles towing vehicles over 10 000 lb (4500 kg) gvw. Acceptable performance requirements are based on data obtained from applicable sections of SAE J786a (March, 1978). The purpose of this recommended practice is to establish the minimum brake system performance requirements with regard to: 3.1 Stopping ability--of cold brakes, as affected by vehicle speed. 3.2 Stopping ability--of hot brakes, as affected by vehicle speed and duty cycle. 3.3 Pedal force (air pressure) requirements--maximum allowable. 3.4 Brake stability. 3.5 stopping ability and recovery of wet brakes. 3.6 Stopping ability of emergency brake system. 3.7 Brake effectiveness distribution for vehicles in combination.
