BRAKE TURBINE SYSTEM BRAKE DRUMS
The Webb BTS Brand
Brakes should stop your trucks on the road – not in the service bay. That’s the idea behind the new Webb
BrakeTurbine System BTS Brake Drums.
The Maintenance Council’s Tomorrow’s Truck Program taskforce recommended the creation of self-cleaning brake
drums and brake linings. Webb Wheel Products, Inc., and Lynnfin Truck Technologies, Inc., answered with the
industry’s first self-cleaning brake system. The new Webb BTS Brake Drums optimize the performance of Lynnfin
BrakeTurbines for a cleaner system to improve brake life and performance.
Heat and debris ruin brakes. BrakeTurbines remove both from brakes by forcing air between the drum and friction
material. But it wasn’t until now that a brake drum was designed to optimize the performance of BrakeTurbines. And
by effectively reducing heat and debris, the Webb BTS Brake Drum may help reduce the amount of noise coming from
your brakes

DRUM BACK/BAND NUMBER CROSS REFERENCE
In the process of manufacture, Centrifuse brake drums
are assigned three different part numbers - for the drum
band, drum back and the drum itself (see illustration).
To avoid confusion and possible misapplication when
ordering replacement drums, refer to the CENTRIFUSE
DRUM part number.
This is for your convenience in matching drum back
numbers to CENTRIFUSE DRUM part numbers.
