high performance premium

NBCB Combo-Block

combo-block creates a dual friction material of semi-metallic
and organic friction. Combined together, they provide superior
stopping power and extended lining life.
Combo-Block passes the inertia dynamometer
requirement of the FMVSS 121 brake
standard at a 23,000 lbs. GAWR when
using an AL factor of 180 (type 30 air
chamber and a 6" slack adjuster) or greater.
For the most demanding applications Combo-Block provides
exceptional heat dissipation, friction stability and good
drum compatibility.

NBMB Masterblock

Masterblock features a medium-friction asbestos-free brake
lining with a glass and acrylic fiber base.
This block passes the inertia dynamometer
requirement of FMVSS 121 brake standard at
a 23,000 lbs. GAWR using an AL factor of
165 (type 30 air chamber and a 5.5" slack
adjuster) or greater.
Masterblock 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.
Masterblock is without question the best performing heavy duty
premium grade brake block on the market today.
