EBC 87-91 BMW M3 2.3 (E30) Front Wear Leads

These brake wear lead sensors from EBC are a smart addition to your braking system, especially if you're working on a BMW from the 80s or early 90s like a 325i or an M3. They're designed to give you an audible or visual warning when your brake pads are getting thin, preventing that costly metal-on-metal contact that can quickly ruin your rotors. Think of them as an early alert system for your brakes.

The sensor itself is a small metal tab that attaches to the brake pad. As the pad wears down, it eventually makes contact with the rotor, creating a squealing sound or triggering a dashboard light. This gives you a heads-up to replace your pads before they cause more serious damage. It’s a simple but effective way to protect your investment in your braking system and avoid a much more expensive repair down the road.
