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

Following a brake pad replacement in a TESLA Model S, there is a guided procedure which is activated by the technician from the main centre display – this is called the Media Control Unit (MCU).

Pick up some tips on the proper procedure for bedding in the brakes on a Model S with this video from the experts at Delphi. We’ll show you:

  • How to enter the vehicle into Service Mode
  • The  settings required to being brake bedding in
  • Why improper setup can end up causing noise, vibration or harshness.

What is the target driving speed for the brake burnishing process?

The Model S onboard computer advises that the required speed you need to hit to start the process of bedding in the brakes is 46 miles per hour.

Why is it important not to bring the vehicle to a standstill?

Braking the vehicle is necessary to perform the burnishing process, but it’s very important not to brake to a complete stop. If this happens, material from the brake pads may transfer to the brake disc. This may cause thickness variation – which will lead to excessive runout and will register to the driver as a juddering feeling.

Where should I drive to bed in the brakes?

You need to choose a suitable route to perform the brake burnishing service. Avoid built-up areas where the speed limit is lower, and make sure you have plenty of room to manoeuvre. You’ll be accelerating and braking quite regularly so your surroundings should be quite clear of cars.

What is speed limit mode on a Tesla?

Speed limit mode is a safety setting directing the vehicle not to exceed the top speed that has been input. In Service Mode the setting is set to On by default, but because you may need to go faster to burnish the brakes we recommend setting it to Off before commencing the bedding in procedure.
