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

Brake fluid is an essential part of the braking system. It acts as part of the hydraulic system which allows the brakes to function correctly. There’s a lot to remember about testing and checking brake fluid, so here’s a reminder. 

Brush up on brake fluid with this helpful video from the expert technicians at Delphi. We’ll go over some of the most important information ready for the next time you tackle these issues, including: 

  • Where to locate the brake fluid reservoir 
  • What the different DOT ratings mean 
  • When to check and when to change brake fluid.

What brake fluid do I need? 

You can find out which brake fluid the vehicle in question needs by looking at the cap on the brake fluid reservoir. There should be a DOT number written on there, which will tell you which specification you need. 

How often should brake fluid be changed? 

We recommend checking a vehicle’s brake fluid once a year, and changing it every two years to help your brakes stay in good shape. 

What does brake fluid do? 

Through hydraulic pipe, brake fluid converts the moment of the brake pedal, to the movement of the pad or shoe, on to the disc or drum. It also acts as a lubricant to keep the moving parts of the system working effectively. 

How do I check brake fluid level? 

Simply find the brake fluid reservoir in the engine bay. You can check the level of the brake fluid with a look at the clearly marked level indicators for Min and Max level. The ideal level is between these two markers. 

The fluid should also be checked for water content, as brake fluid will absorb water over time.
