NB225-FF Extra HD Brake Linings
Description
NB225-FF extra HD brake linings are a heavyweight workhorse for long-haul demands. Assure quiet, dependable stopping power and outstanding block life. Especially formulated with highly enriched aramid fibers, along with the finest materials available. Protect cargo and driver. Help lower operating costs. Perfect for buses, trucks and trailers, where reserve braking capabilities and fast stops are essential.
NB225-FF passes the inertia dynamometer requirement of the FMVSS 121 brake standard at a 23,000 lb. GAWR when using an AL factor of 165 (type 30 air chamber and a 5.5″ slack adjuster) or greater.
NB225-FF extra HD brake linings are the answer to all the new “hyped”technology blocks. This aramid fiber, resin based formula has a proven track record for delivering safe stopping, extended life, and prolonged drum wear in all applications.
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.
