Anti-lock Brake System (ABS) Sensors

Technology such as anti-lock brakes (ABS) and electronic stability are now common place thanks to the ABS sensor or wheel speed sensor. A small device, it has a big role to play; monitoring the wheel’s speed and rotation to prevent the brakes from locking. So, it’s important to always fit an OE quality part - anything less could compromise the effectiveness of these safety critical systems. Featuring weather pack connectors and plated pins, and rigorously tested to OE standards, Delphi ABS sensors deliver optimum signal stability and reliability in all conditions, for an accurate, long-lasting sensor that you can fit with confidence.

Latest OE technology

Our ever-expanding range of ABS sensors features the latest digital signal technology. By creating a digital, square wave, Delphi magneto resistive and hall effect sensors only change frequency, not amplitude, improving accuracy, especially at lower speeds. They can also detect the direction of the wheels; forward, reverse and even stop. This is vital for hill hold control, autohold and automatic parking assistance technologies.

Protection from the elements

Given its position, the ABS sensor is particularly vulnerable to contamination from dirt and moisture. That’s why Delphi ABS sensors feature weather-pack connectors that lock out dirt, moisture, chemicals and other contaminants, coupled with plated pins for even great corrosion protection and improved conductivity.

Extreme testing

Water, heat and vibration can all affect a sensors characteristic. So we subject all our sensors to extensive thermal, shock and vibration testing just to be sure. With test temperatures ranging from -40 o C to 140 o C, we know they’ll perform even in the most challenging conditions. Delivering optimum stability and reliability at all times.

Easy installation

For right-fist-time fitment, Delphi ABS sensors are designed to match the OE. With like-for-like mounting and connector designs and wire lengths, technicians can fit quickly and easily, straight from the box.

The complete solution

As well as a growing range of ABS sensors, we also offer advanced diagnostic capability including the ability to read live fault codes and individual wheel speed data, essential repair data through our vehicle technical information package, and expert training and technical support.

Resource Highlights

From removal to fit, learn how to replace worn brake discs and pads with a Delphi Technologies Expert.
 

How do I remove the disk if it’s stuck? 


It is common for the disk to be stuck to the hub. To loosen it, go around the friction surface of the disk hitting it with a hammer until it becomes free. 


How do I clean the hub? 


Go around the whole hub using a wire brush (ideally on a drill) to make it spotless, paying particular attention to both the flat surface and angled surface where the disc locates.  


Where do I apply high temperature grease? 


Place it around the hub to prevent the disk from sticking to the hub. 


How do I check the replacement disks are the same before fitting? 


Simply put the new disk over the old one to make sure they are the same diameter. Then, place them side by side to make sure that they’re the same height. 


Why do I have to retract the brake caliper piston? 


Without the caliper piston being retracted, the new brake pads will not fit.  The new pads will be deeper than the existing worn ones. 


Do I need to clean the disks before fitting? 


No, you can put the disks straight on if they are Delphi Geomet coated. This makes them easier to fit as you don’t need to clean off any transport oil. There is also the added benefit that they are long-lasting as this coating provides superior protection against corrosion. 


How do I clean the caliper carrier before refitting? 


To clean the caliper carrier, use a wire brush at the points where the pads slide in and out of the carrier. 


How do I know which way to fit the new pad? 


On directional pads, there will be anarrow marked on backing plate showing the direction the wheel turns. It also has a small cut-out on the side which aligns to the piston on the inside.
