Porsche Taycan Brake Pad Wear Sensor in US

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

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

Why Replace the Wear Sensor at Every Porsche Taycan Pad Change

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

Signs the Wear Sensor on Your Porsche Taycan Needs Replacing

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

Why GeoBrakes for the Porsche Taycan Brake Pad Wear Sensor

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

Frequently Asked Questions - Porsche Taycan Brake Pad Wear Sensor

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

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

Does my Porsche Taycan have electronic brake pad wear sensors?

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

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

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