Porsche Cayman Brake Pad Wear Sensor in US

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

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

Why Replace the Wear Sensor at Every Porsche Cayman Pad Change

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

Signs the Wear Sensor on Your Porsche Cayman Needs Replacing

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

Why GeoBrakes for the Porsche Cayman Brake Pad Wear Sensor

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

Frequently Asked Questions - Porsche Cayman Brake Pad Wear Sensor

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

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

Does my Porsche Cayman have electronic brake pad wear sensors?

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

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

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