For ultimate brake lining performance and life, NB1088-FF cohesive friction linings last twice as long as traditional abrasive-friction linings, while protecting drum surfaces from wear and reducing brake noise.
NB1088 Cohesive Friction Linings
Description
The NB1088 cohesive friction brake block is the ultimate brake lining – the only lining, in fact, you need regardless of your application. From OTR to Transit, the NB1088 lining delivers longest life.
Formulated with special chemicals that bleed out of the lining during braking, the NB1088 lining develops a thin film on itself and the drum wall to create non-abrasive or cohesive friction. As a result, there’s less heat, no damage to the drum’s surface, and brake noise is reduced.
Best of all, linings last twice as long – or your next round of linings is on us.
Key Advantages
- Offers twice the life of abrasive linings – guaranteed as part of the Triple Double Guarantee.
- Promotes up to twice the drum life
- Eliminates drum hot spotting and thermal cracking
- Reduces uneven tire wear
- Increases wheel-end component life
- Extends maintenance and replacement intervals
NB1088-FF brake blocks pass the inertia dynamometer requirement of the FMVSS 121 brake standar d at a 23,000 lb. GAWR when using an AL factor of 165 (type 30 air chamber and 5.5″ slack adjuster) or greater for OTR applications.
For our Transit block, the NB1088-FF lining passes the inertia dynamometer requirement of the FMVSS 121 brake standard at a 26,000 lb. GAWR when using a type 30 air chamber and 7.0″ slack adjuster.
Ultimate Formulation
- Superior, asbestos-free matrix
- Absence of conventional abrasives
- Special ingredients to promote controlled transfer film
- Film thickness 1 to 1.5 micron
- Friction developed due to cohesive forces at molecular level
- Special ingredients to control & condition film inter action
- Heat sink particles to lower the rubbing surface temperature
- Meets or exceeds FMVSS 121
Cohesive Friction Application
Recommended for use on trucks, tractors, and trailers, as well as transit, city bus, and refuse applications. Choose between our OTR/heavy-duty (23,000 lbs.) and Transit/severe-duty (26,000 lbs.) blocks.
