ABS rings for Peugeot 407 SW
The Peugeot 407 SW is a model that combines sleek design with practical versatility, but its advanced chassis demands that all drivetrain components work in flawless harmony. The ABS ring is a small yet crucial part that is frequently overlooked until warning lights illuminate on the instrument cluster. On a Peugeot 407 SW, these rings are particularly exposed to harsh European winters with road salt, moisture and fluctuating temperatures, making them a common wear item over time. As drivetrain specialists, we ensure you receive the right components engineered to withstand the daily stresses your car faces, whether driving in heavy city traffic or on long motorway journeys.
What does the ABS ring do on a Peugeot 407 SW?
The ABS ring on a Peugeot 407 SW serves as the core of the speed monitoring system for each individual wheel. Mounted on the rotating section of the CV joint, it features a precise pattern of teeth or magnetic poles. As the wheel turns, an electrical pulse is generated in the ABS sensor positioned right beside the ring. This signal is instantly transmitted to the engine control unit, which calculates within milliseconds whether a wheel is about to lock up or lose traction. For the Peugeot 407 SW, the precision of these pulses is vital so that systems such as electronic brakeforce distribution (EBD) and electronic stability programme (ESP) intervene correctly and safely during emergency braking or evasive manoeuvres.
Common signs of wear
There are several clear indications that your ABS ring is failing or has cracked. The most obvious is an ABS or ESP warning light glowing continuously or intermittently while driving. Another very common symptom on the Peugeot 407 SW is a pulsating or juddering brake pedal under completely normal braking at low speeds, such as when rolling up to a junction. This is often caused by rust building up beneath the ring on the constant velocity joint, forcing the ring to expand and eventually crack. As it expands, the tooth spacing becomes uneven, tricking the sensor into registering wheel lock-up even during gentle braking on dry tarmac.
How to choose the correct ABS ring
Finding the right ABS reluctor ring for your Peugeot 407 SW requires care, as technical specifications vary depending on engine variant and gearbox type. Key dimensions to verify are the tooth count, the inner diameter to ensure a snug fit on the CV joint, and the overall width of the ring. A ring with the incorrect tooth count will feed faulty speed data to the onboard computer, preventing safety systems from functioning correctly. We strongly recommend selecting your vehicle by make, model and engine to guarantee an exact fit. Before fitting, thoroughly clean any rust and grime from the seating surface on the CV joint to ensure the new ring sits straight and will not crack during installation.
Related parts to inspect
You may also wish to check these exact pages for the same vehicle when working on the ABS ring:
When one drivetrain component shows signs of wear, neighbouring parts on the same car often require inspection as well. Comparing these exact pages for the Peugeot 407 SW makes it easier to determine whether the issue lies solely with the ABS ring or another connected component in the power delivery system.
This is especially true on models where vibrations, play and unusual noises can travel across multiple components in the drivetrain. A quick check of related categories reduces the risk of replacing the correct component type while overlooking an adjacent part that causes the same symptoms.

Frequently asked questions about ABS rings for Peugeot 407 SW
How do I know if the ABS ring on my Peugeot 407 SW is damaged?
The most common symptoms are an illuminated ABS warning light or an unwanted pulsation in the brake pedal when braking at low speeds. A visual inspection will often confirm whether the ring is cracked or heavily corroded.
Can I replace just the ABS ring, or do I need to replace the entire CV joint?
On the Peugeot 407 SW, you can easily replace just the ABS ring if the CV joint itself is still in good condition. This is a cost-effective solution compared to replacing the complete joint.
Why do ABS rings crack on the Peugeot 407 SW?
This is usually caused by corrosion. Rust builds up between the CV joint and the ring, creating outward pressure that eventually causes the ring to crack and expand.
Will a broken ABS ring cause an MOT or roadworthiness test failure?
Yes. If the ABS warning light is lit or the system is not functioning correctly, the car will fail its roadworthiness inspection because it is classed as a major safety defect.
How do I find the correct tooth count on the ABS ring for my car?
The easiest and most reliable way is to select your Peugeot 407 SW model, year and engine on our website. We will then filter out the rings that are engineered to fit your specific car.
