NBMB-FF extra heavy duty premium brakes are an excellent choice and without question the best performing HD premium-grade brake blocks on the market today.
NBMB-FF Extra Heavy Duty Premium Brakes
Description
NBMB-FF extra heavy duty premium brakes feature a medium-friction asbsetos-free brake formula and a glass and acrylic base.
These brake blocks pass the interia dynamometer requirement of FMVSS 121 brake standard at a 23,000 lb. GAWR using an AL factor of 165 (type 30 air chamber and a 6” slack adjuster) or greater.
NBMB-FF has superior durability and friction stability, characteristics available only in premium grade materials. It’s usable on both Wedge and S-Cam brakes for a wide range of applications, and it provides exceptional performance.
NBMB-FF extra heavy duty premium brakes and without question the best performing HD premium-grade brake linings on the market today.
Application
Recommended for use on S-Cam and Wedge brakes on trucks,tractors and trailers in medium weight applications such as general cargo, furniture, plastics and mail.
