Mercedes Benz G63 Amg Brake Pad Wear Sensor in US

A disc brake pad wear sensor on the Mercedes Benz G63 Amg is your vehicle's advance warning system for brake pad replacement. It eliminates the need to rely on audible squealing from your G63 Amg to know your pads are getting thin, instead triggering a dashboard warning light at a preset minimum thickness on the Mercedes Benz G63 Amg, giving you time to plan the replacement before the pads wear through to the metal backing plate. Replacing a triggered sensor with every G63 Amg 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 G63 Amg

The wear sensor on the Mercedes Benz G63 Amg is a small probe embedded in or clipped to the brake pad. When the G63 Amg pad wears down to the replacement threshold, the probe contacts the rotor surface. This contact creates a circuit change that signals the Mercedes Benz G63 Amg ABS or brake control module, illuminating the brake warning light. Once the probe on the Mercedes Benz G63 Amg has contacted the rotor, it is destroyed and cannot be reused. It is a single-use component by design on the G63 Amg.

Why Replace the Wear Sensor at Every Mercedes Benz G63 Amg Pad Change

Installing fresh brake pads on the Mercedes Benz G63 Amg without fitting a new wear sensor defeats the entire purpose of having a brake monitoring system on your G63 Amg. A previously triggered sensor probe is worn through and has no remaining material to detect the next set of G63 Amg pads wearing down. From day one of the new Mercedes Benz G63 Amg brake pads, the warning system is non-functional without a new sensor.

Signs the Wear Sensor on Your Mercedes Benz G63 Amg Needs Replacing

• Brake warning light staying on your Mercedes Benz G63 Amg after new pads have been fitted
• Intermittent brake warning light on your G63 Amg that clears and returns without obvious cause
• Visible wear notch or contact mark on the Mercedes Benz G63 Amg sensor probe tip
• OBD fault codes on your G63 Amg referencing the brake pad monitoring circuit

Why GeoBrakes for the Mercedes Benz G63 Amg Brake Pad Wear Sensor

Wear sensor compatibility for the Mercedes Benz G63 Amg is more exacting than most brake parts. The probe length, contact resistance specification, and connector design must all match the G63 Amg brake monitoring circuit precisely. A wrong sensor triggers Mercedes Benz G63 Amg 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 G63 Amg, with front and rear positions listed separately.

Frequently Asked Questions - Mercedes Benz G63 Amg Brake Pad Wear Sensor

Do I need to replace the brake pad wear sensor every time I change pads on my Mercedes Benz G63 Amg?

Yes, on Mercedes Benz G63 Amg vehicles equipped with electronic wear sensors. The sensor probe on your G63 Amg is a single-use component. Once it has contacted the rotor and triggered the G63 Amg warning light, the probe is consumed. Always replace the Mercedes Benz G63 Amg sensor during every pad change.

Does my Mercedes Benz G63 Amg have electronic brake pad wear sensors?

Many vehicles use a mechanical wear indicator instead of electronic sensors. Check your Mercedes Benz G63 Amg owner's manual or use the GeoBrakes vehicle selector to confirm whether your G63 Amg uses an electronic pad monitoring system.

Can a faulty wear sensor keep the brake warning light on my Mercedes Benz G63 Amg on after new pads are installed?

Yes. If the Mercedes Benz G63 Amg wear sensor from a previous brake service was not replaced, or if the probe has been damaged on your G63 Amg, the brake warning light will remain on even with new pads. Replacing the G63 Amg sensor will clear the fault and restore normal operation.
