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

Changing brake fluid on a vehicle is an essential maintenance job. It needs to be performed because brake fluid loses its performance over time due to it absorbing water, which then leads to bubbles in the fluid.

In this Masters of Motion video, our Delphi expert demonstrates how to change the brake fluid on a Tesla Model S, sharing:

• How to remove the existing brake fluid
• How to perform the brake bleed
• Tips when working on an electric vehicle 

How often does brake fluid need changing?

Most manufacturers recommend changing the brake fluid in their vehicles once every two years as it plays such an important safety function. 

What do I need to perform an oil change?

To change the oil on a Tesla Model S, the main pieces of equipment our Delphi expert uses are new brake fluid, a pressure bleeder and the Delphi DS480 Diagnostic Tool.

How can I tell if the brake fluid needs changing?

First, there is the manufacturer’s recommended period between changes to follow. You can also look for signs that it needs changing, such as the fluid looking dirty or smelling burnt, the brake pedals being spongy, or the fluid level having dropped in the reservoir.

What is a frunk?

This is the name Tesla gives to the storage space at the front of the vehicle. The name is a mix of the words ‘front’ and ‘trunk’.
