SERVICE BRAKE SYSTEM PERFORMANCE REQUIREMENTS—TRUCK & BUS
1969-06-01
HISTORICAL
J992A_196906
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.

In-Service Brake Performance Test Procedure--Vehicles Over 4500 kg (10 000 lb)
2000-09-29
CURRENT
J1250_200009
This SAE Recommended Practice establishes a uniform practical series of subprocedures for level road testing of the brake performance of vehicles with gross vehicle weight ratings over 4500 kg (10 000 lb). The purpose of this practice is to establish a uniform method for use by operators and law enforcement agencies, to evaluate the condition of the brake systems of vehicles with GVWRs and GCWRs over 4500 kg (10 000 lb) under any condition of loading. By following the test procedures set forth, the operator and/or law enforcement agencies can ascertain if the vehicle meets the service brake and emergency brake stopping distance requirements of applicable State and Federal regulations.

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.
