For the most demanding applications NBCB-FF/FF high performance linings provide exceptional heat dissipation, friction stability and improved drum compatibility.
NBCB-FF/FF Premium High Performance Linings
Description
NBCB-FF/FF high performance linings are a dual friction material, combining a semi-metallic with an organic friction formula. Combined together, they provide superior stopping power and extend lining life.
NBCB-FF/FF brake blocks pass 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.
For the most demanding applications NBCB-FF/FF high performance linings deliver exceptional heat dissipation, friction stability and good drum compatibility for optimal stopping power and lining life.
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.
