4-wheel antilock, 4-wheel disc brakes

The 4-wheel antilock disc brakes with HydroBoost on Suburban® are standard. ABS is designed to help keep the vehicle's wheels rotating as the brakes assist the driver in achieving a controlled stop. Once activated, all 4-wheel ABS sensors monitor wheel rotation. Based on continual sensor monitoring feedback, they repeatedly release and apply pressure to the brakes, helping to eliminate wheel lockup while retaining driver steering ability. This feature is available only on 3/4 ton models.
