Brake Lining Program

Aftermarket Heavy Duty Truck Brake Lining Qualification Program

T.M.C. RP 628B - (Technology & Maintenance Council Recommended Practice #628B) 

The purpose of this Recommended Practice (RP) is to provide information for judging the performance of aftermarket brake linings on air-actuated foundation brakes, including testing in accordance with the dynamometer test procedure in Federal Motor Vehicle Safety Standard (FMVSS) 121 and lining supplier qualification information.  Such information will assist fleet operators in choosing aftermarket brake linings that will perform adequately on typical combination (tractor/trailer) vehicles and single trucks.

Why is this important?  Selecting the correct replacement brake linings for heavy duty trucks is an important component in the overall safety of the vehicle.  It is essential that the replacement brake linings function as well as the material originally supplied on the vehicle.

Brake Lining Review Institute Program - Program Document PD5000 (14-Aug-08)

What is the history of the program?

1993 - American Trucking Association's The Maintenance Council - now Technology & Maintenance Council (TMC) requested the Society of Automotive Engineers (SAE) develop a program using data generated from tests run in accordance with TMC Recommended Practice 628A and Federal Motor Vehicle Safety Standard (FMVSS) 121 to evaluate after-market heavy-duty truck brake linings.

1994 - SAE created the Brake Lining Review Institute. Under the guidance of the SAE Performance Review Board, the Brake Lining Review committee administered the program.

2000 - SAE transferred the administration of the program to the Performance Review Institute (PRI) but the procedural and structural set-up are essentially unchanged.
