The ABS EBS control module is the brain of heavy truck braking. It processes wheel speed data and calculates the braking force needed for each axle. It responds faster than standard pneumatic brakes. This prevents jackknifing and keeps the trailer aligned with the cab under hard stops.
EBS uses electronic signals instead of air pressure to trigger the brakes. This cuts response time in half. If the module detects a fault, it shuts down the electronic assist and reverts to standard air brakes.
