A disc brake pad wear sensor on the Porsche 718 Spyder is your vehicle's advance warning system for brake pad replacement. It eliminates the need to rely on audible squealing from your 718 Spyder to know your pads are getting thin, instead triggering a dashboard warning light at a preset minimum thickness on the Porsche 718 Spyder, giving you time to plan the replacement before the pads wear through to the metal backing plate. Replacing a triggered sensor with every 718 Spyder pad change is the only way to keep that early-warning system working for the next service interval.
The wear sensor on the Porsche 718 Spyder is a small probe embedded in or clipped to the brake pad. When the 718 Spyder pad wears down to the replacement threshold, the probe contacts the rotor surface. This contact creates a circuit change that signals the Porsche 718 Spyder ABS or brake control module, illuminating the brake warning light. Once the probe on the Porsche 718 Spyder has contacted the rotor, it is destroyed and cannot be reused. It is a single-use component by design on the 718 Spyder.
Installing fresh brake pads on the Porsche 718 Spyder without fitting a new wear sensor defeats the entire purpose of having a brake monitoring system on your 718 Spyder. A previously triggered sensor probe is worn through and has no remaining material to detect the next set of 718 Spyder pads wearing down. From day one of the new Porsche 718 Spyder brake pads, the warning system is non-functional without a new sensor.
Wear sensor compatibility for the Porsche 718 Spyder is more exacting than most brake parts. The probe length, contact resistance specification, and connector design must all match the 718 Spyder brake monitoring circuit precisely. A wrong sensor triggers Porsche 718 Spyder 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 718 Spyder, with front and rear positions listed separately.
Do I need to replace the brake pad wear sensor every time I change pads on my Porsche 718 Spyder?
Yes, on Porsche 718 Spyder vehicles equipped with electronic wear sensors. The sensor probe on your 718 Spyder is a single-use component. Once it has contacted the rotor and triggered the 718 Spyder warning light, the probe is consumed. Always replace the Porsche 718 Spyder sensor during every pad change.
Does my Porsche 718 Spyder have electronic brake pad wear sensors?
Many vehicles use a mechanical wear indicator instead of electronic sensors. Check your Porsche 718 Spyder owner's manual or use the GeoBrakes vehicle selector to confirm whether your 718 Spyder uses an electronic pad monitoring system.
Can a faulty wear sensor keep the brake warning light on my Porsche 718 Spyder on after new pads are installed?
Yes. If the Porsche 718 Spyder wear sensor from a previous brake service was not replaced, or if the probe has been damaged on your 718 Spyder, the brake warning light will remain on even with new pads. Replacing the 718 Spyder sensor will clear the fault and restore normal operation.
