1. Understanding the ABS Brake Control System in Your Mercedes ML350
The Anti-lock Braking System (ABS) is a critical safety feature in your Mercedes ML350, designed to prevent wheel lock-up during sudden or intense braking. This system works in tandem with Electronic Brake-force Distribution (EBD) to ensure optimal braking performance. According to the National Highway Traffic Safety Administration (NHTSA), ABS can reduce the risk of crashes by approximately 10-15%.
The system uses sensors to monitor the rotation speed of each wheel in real-time. If the system detects that a wheel is about to lock due to excessive braking, it electronically adjusts the braking force to that wheel. This modulation of brake pressure allows you to maintain steering control during emergency braking situations. Without ABS, locked wheels can cause the vehicle to skid, making it difficult to steer and potentially leading to accidents.
How ABS Prevents Wheel Lock-Up
- Wheel Speed Sensors: Continuously monitor the rotational speed of each wheel.
