Brake Force Distribution Field Test Procedure for Truck and Bus

2022-10-07
CURRENT
J225_202210
This SAE Recommended Practice provides a field test procedure and instructions for air braked single unit trucks, buses, and combination vehicles. Brake force distribution field testing with systems post-reduce stopping distance changes is still appropriate, however, vehicles with electronically 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 Test of air-braked single and combination vehicles. d Calculation of brake force distribution. e This test procedure is intended to be used as a field procedure. If a more refined method, utilizing laboratory equipment, is required, refer to SAE J1505.

Off-Vehicle Brake Testing for Service Brakes Over 10 000 lb GVW—Air, Hydraulic, and Mechanical Actuation

2009-06-25
HISTORICAL
J2806_200906
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 (10 000 US lb) 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 (a.k.a. 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.
