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