Brakes & Safety

The Western Star 57X offers the entire Detroit Assurance® Suite of Safety Systems, the most advanced safety technology in the industry

Service Brakes Drum Brakes. Air Disc Brakes. WABCO® ABS and optional Hill Start Aid and Traction Control
Active Brake Assist 5 Active Brake Assist 5 (ABA 5) detects distance and speed to moving and stationary objects in its path and determines if braking is necessary. It’s the only system on the market that works down to 5 mph (with Detroit DT12 transmission), making it ideal for travel in congested urban areas. It also recognizes pedestrians who are about to cross in the truck’s path, alerting the operator while partially braking, followed by full braking if the operator does not react.
Adaptive Cruise Control Detroit Assurance technology enables state-of-the-art features such as Adaptive Cruise Control (ACC) to 0 mph to ease driving in stop-and-go traffic, as well as help mitigate front and rear collisions.
Brake Hold Mode Whether stopped in heavy traffic or for any other reason, this state-of-the-art feature can keep a truck (with DT12 Transmission) stopped when the driver removes their foot from the brake. Brake Hold Mode can be engaged by pressing the brake pedal all the way down. It automatically disengages when the driver accelerates.
Lane Keep Assist Lane Keep Assist (LKA) reads and tracks lane markers to help drivers keep their trucks centered in their lane.
Lane Departure Protection This safety feature (LDP) detects when a truck drifts out of its lane and then actively steers it back on course.
Side Guard Assist A game changer for safety, Side Guard Assist (SGA) detects objects on the passenger side of the truck and alerts the operator.
Active Side Guard Assist This industry leading technology detects and actively prevents the truck from making a right turn into moving cyclists and pedestrians in urban situations
