Is your car's 'check brake' light on? It might just be a worn-out wear indicator, not the pads themselves. This Brembo A00206 is a pack of two genuine replacement wear indicator sensors. These little sensors clip onto certain brake pads, and when the pad material wears down enough, it grinds against the sensor, completes a circuit, and triggers a warning light on your dashboard. Brembo is a top-tier brand in braking, so this part meets or exceeds the original equipment manufacturer (OEM) specifications. It's a simple, inexpensive part that can save you a diagnostic fee at the shop. Just make sure it's the correct part number for your specific vehicle make and model. Usually an easy swap when you're changing your brake pads. Keep your braking system in proper working order with quality parts.
