Why Are Brake Telematics So Tough for Class 8 Trucks?

January 30, 2026

Brakes are the final frontier for telematics on Class 8 trucks. But Hendrickson Vehicle Systems is close to a breakthrough that may change the game when it comes to getting real-time brake system information back to fleets. HDT talked to Jeff Moris, director, axle, brake and wheel-end systems at Hendrickson to find out more about how these new telematics technology will work.

Key takeaways:

Brakes are a harsh environment for electronics, which is why they have been a “last frontier” for heavy-duty telematics.
The bigger brake telematic opportunity for fleets may be with trailers, not tractors.
Disc brakes already have a head start on sensing, including basic wear sensors and more advanced continuous wear monitoring.
The real challenge is bringing meaningful sensing to drum brakes, because drum brakes still dominate U.S. trailers.
Getting the data to the right person fast is as important as sensing it.
