    Burnt ABS Pump Controller: Failure Symptoms and Why You Should Choose an Original Used Part

    The ABS (Anti-lock Braking System) is the foundation of active safety in every modern vehicle. Its main task is to prevent the wheels from locking during sudden braking, allowing the driver to maintain full control over the car in emergency situations.
