The brake pad warning light on your Land Rover Discovery Sport is a crucial safety feature, illuminating when your brake pads wear down and require replacement. While this system is generally reliable, occasional glitches or a simple reset after a brake pad change might be necessary. This comprehensive guide will walk you through understanding the warning light, potential issues, and steps to reset it.
Understanding Your Land Rover Discovery Sport Brake Pad Warning System
Your Discovery Sport employs a sophisticated electronic system to monitor brake pad wear. Sensors within the brake pads themselves detect thinning and trigger the warning light on your dashboard. This usually manifests as a yellow or red illuminated circle with the word “BRAKE” or a brake pad symbol.

Common Reasons for the Brake Pad Warning Light
While worn brake pads are the most common culprit, several other factors can trigger the warning light:
- Worn Brake Pad Sensors: The sensors themselves can wear out or get damaged, leading to a false warning.
- Faulty Wiring: A break in the wiring connecting the sensors to the vehicle’s electrical system can disrupt the signal.
- Low Brake Fluid: The brake pad warning system is often linked to the brake fluid level sensor. Low brake fluid can trigger both warning lights.
- Electronic Glitch: Like any electronic system, temporary glitches can occur, illuminating the warning light erroneously.
Resetting the Brake Pad Warning Light After Replacing Brake Pads
After replacing your Discovery Sport’s brake pads, it’s essential to reset the warning system. Here’s a step-by-step guide:
- Ensure Ignition is Off: Before you begin, make sure your vehicle’s ignition is switched off.
- Locate the OBD-II Port: The OBD-II port is typically located under the dashboard on the driver’s side.
- Connect an OBD-II Scanner: Connect a compatible OBD-II scanner to the port.
- Turn the Ignition to ON: Turn the ignition to the “ON” position, but do not start the engine.
- Access the Brake System Menu: Using the scanner’s interface, navigate to the “Brake System” or “Service Reset” menu.
- Select “Brake Pad Reset”: Choose the option for “Brake Pad Reset” or a similar term.
- Follow On-Screen Instructions: The scanner will guide you through the reset procedure, which usually involves confirming the reset and waiting for the system to acknowledge.
- Disconnect the Scanner and Test: Once the reset is complete, disconnect the OBD-II scanner and turn off the ignition. Start your vehicle and check if the warning light has been extinguished.
