If you need to replace worn brake wear sensors and want a kit that fits popular models while resisting rust and simplifying installation, this guide is for you. We tested and compared TRQ replacement kits that include pad wear sensors, rotors and pads across BMW and Mercedes applications. You’ll learn which kits prioritize fit, corrosion resistance, and DIY-friendly installation steps, how each kit performs on fit and durability, and which kit is best for common scenarios. Products were chosen for model match, sensor inclusion, corrosion protection (coated rotors/materials) and customer feedback on fit and ease of install.
Quick Answer
For most DIYers the best pick is the TRQ Front Brake Pad & Rotor Kit (ASIN B0B41ZZ8CD) because it pairs a direct OE fit, a front pad wear sensor, and G-coated rotors that resist corrosion. If you need a budget rear kit for Mercedes ML models choose TRQ Rear Brake Pad & Rotor Kit (ASIN B09HRPTD48).

Frequently Asked Questions
Do these kits include the brake wear sensor or do I have to buy it separately?
Most kits in this roundup include the pad wear sensor for the axle listed in the product title. Check the 'Includes' details on the product page — the TRQ kits explicitly list which sensor (front/rear/driver/passenger) they supply. Always verify fitment for your model year before ordering.
Can a home mechanic install these kits or do I need a shop?
A competent DIYer with basic tools can install these direct-fit kits. Choose kits labeled OE/direct-fit and with included hardware; follow the manufacturer's instructions and a repair manual or video. If you're uncomfortable with caliper torque specs, brake bleeding, or safety procedures, have a professional complete the job.
How can I improve corrosion resistance after installing the kit?
Use the included anti-seize/contact grease on mounting surfaces, tighten lug nuts to spec and keep wheel wells clear of road salt. Coated rotors reduce visible surface rust; for hubs and fasteners, use high-temp anti-seize on non-friction mating surfaces. Regular washing in corrosive climates helps prolong component life.
