Description

NB250-FF high-performance brake linings feature a heavyweight formula for rough-going, demanding off-the-road applications. This exclusive, high-density semi-metallic friction formula resists foreign particle impregnation from dust, dirt, and grit, and assures friction even in high braking temperatures. Protects drums, provides longer life and guards other components against excess heat.

NB250-FF passes 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 6″ slack adjuster) or greater.

NB250-FF blends special steel wool fiber with aramid fibers to produce a block for the most difficult loads and terrain.

 

 

Application

Recommended for use on trucks, tractors, and trailers in all applications including general cargo, stop and go urban driving, bus, grain, liquid hauling, dump trucks and lowboys. Also designed for hydraulic cam brakes and air operated steel axles.
