Jaguar Xjr Brake Pad Wear Sensor in US

A disc brake pad wear sensor on the Jaguar Xjr is your vehicle's advance warning system for brake pad replacement. It eliminates the need to rely on audible squealing from your Xjr to know your pads are getting thin, instead triggering a dashboard warning light at a preset minimum thickness on the Jaguar Xjr, giving you time to plan the replacement before the pads wear through to the metal backing plate. Replacing a triggered sensor with every Xjr pad change is the only way to keep that early-warning system working for the next service interval.

How the Brake Pad Wear Sensor Works on the Jaguar Xjr

The wear sensor on the Jaguar Xjr is a small probe embedded in or clipped to the brake pad. When the Xjr pad wears down to the replacement threshold, the probe contacts the rotor surface. This contact creates a circuit change that signals the Jaguar Xjr ABS or brake control module, illuminating the brake warning light. Once the probe on the Jaguar Xjr has contacted the rotor, it is destroyed and cannot be reused. It is a single-use component by design on the Xjr.

Why Replace the Wear Sensor at Every Jaguar Xjr Pad Change

Installing fresh brake pads on the Jaguar Xjr without fitting a new wear sensor defeats the entire purpose of having a brake monitoring system on your Xjr. A previously triggered sensor probe is worn through and has no remaining material to detect the next set of Xjr pads wearing down. From day one of the new Jaguar Xjr brake pads, the warning system is non-functional without a new sensor.

Signs the Wear Sensor on Your Jaguar Xjr Needs Replacing

• Brake warning light staying on your Jaguar Xjr after new pads have been fitted
• Intermittent brake warning light on your Xjr that clears and returns without obvious cause
• Visible wear notch or contact mark on the Jaguar Xjr sensor probe tip
• OBD fault codes on your Xjr referencing the brake pad monitoring circuit

Why GeoBrakes for the Jaguar Xjr Brake Pad Wear Sensor

Wear sensor compatibility for the Jaguar Xjr is more exacting than most brake parts. The probe length, contact resistance specification, and connector design must all match the Xjr brake monitoring circuit precisely. A wrong sensor triggers Jaguar Xjr warnings at the wrong pad thickness, or not at all. Every sensor in the GeoBrakes catalogue is sourced to original equipment probe and connector specifications for the Jaguar Xjr, with front and rear positions listed separately.

Frequently Asked Questions - Jaguar Xjr Brake Pad Wear Sensor

Do I need to replace the brake pad wear sensor every time I change pads on my Jaguar Xjr?

Yes, on Jaguar Xjr vehicles equipped with electronic wear sensors. The sensor probe on your Xjr is a single-use component. Once it has contacted the rotor and triggered the Xjr warning light, the probe is consumed. Always replace the Jaguar Xjr sensor during every pad change.

Does my Jaguar Xjr have electronic brake pad wear sensors?

Many vehicles use a mechanical wear indicator instead of electronic sensors. Check your Jaguar Xjr owner's manual or use the GeoBrakes vehicle selector to confirm whether your Xjr uses an electronic pad monitoring system.

Can a faulty wear sensor keep the brake warning light on my Jaguar Xjr on after new pads are installed?

Yes. If the Jaguar Xjr wear sensor from a previous brake service was not replaced, or if the probe has been damaged on your Xjr, the brake warning light will remain on even with new pads. Replacing the Xjr sensor will clear the fault and restore normal operation.
