Omfang

This SAE Recommended Practice provides the test procedure and instructions for air braked single unit trucks, buses, and combination vehicles. Brake force distribution testing with systems post-reduced stopping distance changes is still appropriate; however, vehicles with electrononically controlled braking systems are not covered in this document and may need to be addressed in the future. It also provides recommendations for: a. Instrumentation and equipment. b. Vehicle preparation. c. Calculating distribution of brake force. Purpose This procedure provides a method to determine the brake force distribution and threshold pressures for trucks and buses with a GVWR greater than 4536 kg (10000 pounds). Other equipment and procedures could be used to determine approximate relative work or energy being absorbed by a vehicle’s brakes. A performance-based brake tester can determine low pressure/low speed torques of different brakes. A temperature/thermal balance can show relative temperatures of brakes, thus indicating approximate energy absorbed.
