What does a brake wear sensor do?

A brake wear sensor connects to your brake pad. When the pad wears down to a specific thickness, the sensor makes contact with the rotor, triggering a warning light on your dashboard to indicate it's time for new pads.

Why is it important to replace brake pads when the wear sensor activates?

If you continue to drive with worn-out brake pads after the sensor has activated, the metal backing of the pad will grind against the rotor. This metal-on-metal contact can severely damage your brake rotors, leading to more expensive repairs.

Should I replace both front wear sensors at the same time?

It's generally recommended to replace both front wear sensors when you replace your front brake pads, especially if the old ones are worn or damaged. This ensures consistent warning system functionality.

Product Details

EBC is known for making a wide range of brake components, and these front wear leads are a simple but important part of your M3's braking system. They're designed to give you an early warning before your brake pads wear down completely, which can save your rotors from serious damage.

This sensor connects to your brake pad and, when the pad material wears down to a certain point, it makes contact with the rotor. This contact triggers a warning light on your dashboard, letting you know it's time to replace your brake pads. It's a straightforward way to avoid costly repairs down the road by catching pad wear before it becomes a metal-on-metal situation.

This part is specifically made for your 2008-2013 BMW M3. It's a good idea to replace these whenever you're changing your front brake pads, especially if the old ones are worn out or damaged.
