What are ABS and EBS, and what do they do on heavy commercial vehicles?

The electronics that manage wheel lock and stability under braking. Parts and diagnosis are two sides of the same job.

ABS (Anti-lock Braking System) stops the wheels from locking. EBS (Electronic Braking System) distributes brake pressure electronically and plays a key role in keeping the tractor unit and semi-trailer balanced.

Why it matters on the road and at inspection

Braking efficiency is one of the first things checked at the annual inspection. An ABS/EBS fault is a safety issue and also takes the vehicle off the road. Sensor, module or valve faults need an accurate diagnosis.
