Why should I replace my brake pad wear sensors?

Brake pad wear sensors alert you when your brake pads have worn down to a critical level. Replacing them with new ones ensures you get accurate warnings, helping you avoid further damage to your rotors and maintain safe braking performance.

How do I know if my brake pads need replacing based on the sensor?

When the brake pads wear down enough, the sensor will make contact with the rotor, triggering a warning light on your dashboard. This indicates it's time to inspect and likely replace your brake pads.

Product Details

When you're replacing your brake pads, don't forget the wear sensors. This electronic brake pad wear sensor from PowerStop is built to meet the same form, fit, and function as the original part on many BMW 3 Series models from the 1980s and early 1990s, like the 1984-1985 BMW 318i or the 1987-1991 BMW 325i.

PowerStop tests these sensors at temperatures up to 500 degrees Fahrenheit to make sure they hold up and provide reliable conductivity, even under heavy braking. They include all the necessary grommets, mounting clips, and cable protection sleeves to ensure a watertight connection and a straightforward installation. You won't need to make any modifications; it's designed to be a direct replacement.
