Lexus Ls460 Brake Pad Wear Sensor in US

A disc brake pad wear sensor on the Lexus Ls460 is your vehicle's advance warning system for brake pad replacement. It eliminates the need to rely on audible squealing from your Ls460 to know your pads are getting thin, instead triggering a dashboard warning light at a preset minimum thickness on the Lexus Ls460, giving you time to plan the replacement before the pads wear through to the metal backing plate. Replacing a triggered sensor with every Ls460 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 Lexus Ls460

The wear sensor on the Lexus Ls460 is a small probe embedded in or clipped to the brake pad. When the Ls460 pad wears down to the replacement threshold, the probe contacts the rotor surface. This contact creates a circuit change that signals the Lexus Ls460 ABS or brake control module, illuminating the brake warning light. Once the probe on the Lexus Ls460 has contacted the rotor, it is destroyed and cannot be reused. It is a single-use component by design on the Ls460.

Why Replace the Wear Sensor at Every Lexus Ls460 Pad Change

Installing fresh brake pads on the Lexus Ls460 without fitting a new wear sensor defeats the entire purpose of having a brake monitoring system on your Ls460. A previously triggered sensor probe is worn through and has no remaining material to detect the next set of Ls460 pads wearing down. From day one of the new Lexus Ls460 brake pads, the warning system is non-functional without a new sensor.

Signs the Wear Sensor on Your Lexus Ls460 Needs Replacing

• Brake warning light staying on your Lexus Ls460 after new pads have been fitted
• Intermittent brake warning light on your Ls460 that clears and returns without obvious cause
• Visible wear notch or contact mark on the Lexus Ls460 sensor probe tip
• OBD fault codes on your Ls460 referencing the brake pad monitoring circuit

Why GeoBrakes for the Lexus Ls460 Brake Pad Wear Sensor

Wear sensor compatibility for the Lexus Ls460 is more exacting than most brake parts. The probe length, contact resistance specification, and connector design must all match the Ls460 brake monitoring circuit precisely. A wrong sensor triggers Lexus Ls460 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 Lexus Ls460, with front and rear positions listed separately.

Frequently Asked Questions - Lexus Ls460 Brake Pad Wear Sensor

Do I need to replace the brake pad wear sensor every time I change pads on my Lexus Ls460?

Yes, on Lexus Ls460 vehicles equipped with electronic wear sensors. The sensor probe on your Ls460 is a single-use component. Once it has contacted the rotor and triggered the Ls460 warning light, the probe is consumed. Always replace the Lexus Ls460 sensor during every pad change.

Does my Lexus Ls460 have electronic brake pad wear sensors?

Many vehicles use a mechanical wear indicator instead of electronic sensors. Check your Lexus Ls460 owner's manual or use the GeoBrakes vehicle selector to confirm whether your Ls460 uses an electronic pad monitoring system.

Can a faulty wear sensor keep the brake warning light on my Lexus Ls460 on after new pads are installed?

Yes. If the Lexus Ls460 wear sensor from a previous brake service was not replaced, or if the probe has been damaged on your Ls460, the brake warning light will remain on even with new pads. Replacing the Ls460 sensor will clear the fault and restore normal operation.
