Description

NBRM-FF HD brake linings feature a robust medium-friction asbestos-free formula with a glass fiber base. NBRM-FF is ideal for use with S-Cam air brakes in general freight long haul applications where high axle weights are not an issue.

NBRM-FF HD brake linings meet the inertia dynamometer requirement of the FMVSS 121 brake standard at a 23,000 lb. GAWR when using an AL factor of 180 (type 30 air chamber and a 6″ slack adjuster) or greater.

NBRM-FF’s performance, wear life, and drum compatibility exceed that of other comparable heavy duty, asbestos-free materials.

 

Application

Recommended for use on S-Cam and Wedge brakes on trucks, tractors and trailers in highway, general freight and long haul applications over moderate terrain.
