The ABS Gear Ring Window Type Gear Ring is an important component in the anti-lock brake system (ABS) of your vehicle. Its function is to prevent your wheels from locking up during braking, which can cause your car to skid and lose control.

The ring is installed in the outer edge of a wheel hub or axle. The sensor inside reads the teeth on the ring as they pass by, allowing the ABS to monitor the speed of each wheel and detect when it is about to lock up or lose traction.
It is a critical part of the ABS system, which means that if it is damaged or malfunctioning, your vehicle's brakes may not work as well. When this happens, it can be very dangerous and could result in an accident.
The most common sign that your ABS ring is broken or malfunctioning is when the ABS light on your dashboard comes on. This is an indication that the ring needs to be replaced as soon as possible.
Other symptoms include pulsating brake pedals and popping sound when you're braking at low speeds, like on ice. These are also signs of a defective ring, which can cause your brakes to work incorrectly and increase the risk of an accident.
