Abs Ring

What Is an ABS Ring?

An ABS ring — also known as a tone ring or reluctor ring — is a toothed metal or magnetic ring mounted on the hub, driveshaft or CV joint. It works with the ABS sensor to measure wheel speed and prevent wheel lock during braking. At A-Z Motor Factors Halifax, we supply OE-quality ABS rings designed for accurate readings and long-lasting performance.

How the ABS Ring Works

The ABS ring rotates with the wheel or driveshaft. As the ABS sensor measures the movement of the ring teeth or magnetic segments, it sends wheel speed data to the ABS control module. This information ensures:

• Smooth, controlled braking

• Prevention of wheel lock

• Proper traction control operation

• Safe emergency stopping

A damaged ABS ring can cause immediate braking and traction issues.

Common Symptoms of a Faulty ABS Ring

Replace your ABS ring if you notice:

• ABS light on dashboard

• Traction control / ESP warning lights

• Pulsing brake pedal

• ABS activating at low speeds

• Inconsistent wheel speed readings

• MOT failure for ABS faults

• Clicking or vibration from the hub area

ABS ring cracks and corrosion are extremely common, especially in UK winters.

Types of ABS Rings We Supply

We stock a complete range of tone rings, including:

• Driveshaft-mounted reluctor rings

• CV joint ABS rings

• Wheel hub tone rings

• Integral magnetic ABS rings

• Bolt-on and press-fit tone rings

• Multi-pole magnetic encoder rings

All parts are built to OE specification for perfect compatibility with modern ABS sensors.

Why ABS Rings Fail

ABS rings are exposed to harsh road conditions. Typical failure causes include:

• Rust and corrosion

• Cracks from temperature changes

• Impact damage

• Worn or missing teeth

• Driveshaft wear

• Magnetic strip degradation

Replacing a faulty ring restores accurate ABS and traction control function.

Left / Right & Vehicle-Specific Fitment

ABS rings vary by:

• Tooth count

• Diameter

• Hub or shaft location

• Sensor type (active or passive)
