Mercedes Benz Amg Gt R Brake Pad Wear Sensor in US

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

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

Why Replace the Wear Sensor at Every Mercedes Benz Amg Gt R Pad Change

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

Signs the Wear Sensor on Your Mercedes Benz Amg Gt R Needs Replacing

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

Why GeoBrakes for the Mercedes Benz Amg Gt R Brake Pad Wear Sensor

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

Frequently Asked Questions - Mercedes Benz Amg Gt R Brake Pad Wear Sensor

Do I need to replace the brake pad wear sensor every time I change pads on my Mercedes Benz Amg Gt R?

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

Does my Mercedes Benz Amg Gt R have electronic brake pad wear sensors?

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

Can a faulty wear sensor keep the brake warning light on my Mercedes Benz Amg Gt R on after new pads are installed?

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