LAS VEGAS, Nev. — ArvinMeritor has launched a new line of hydraulic disc brake rotors with a special coating to protect against oxidation and corrosion.

The patented coating is called ZXP3 and is initially available across three part numbers with more models to be released through the year. The aftermarket solution is well-suited for medium-duty delivery and express delivery vehicles, ArvinMeritor announced.

The new coating will initially be applied to rotors with a cast-in ABS tone ring, and other applications for the coating are being researched and developed, the company says. The coated rotors will be available under the Meritor and Euclid brands through aftermarket distributors beginning this month.

“The coating adheres and seals thoroughly – even the outside edge of the cooling veins get coated -and will not wear or chip when exposed to heat, chemical deicers, wash solutions, pebbles, sand, or grime,” said Dennis Riedel, hydraulic brake product manager, aftermarket. “After extensive testing both in the lab and in actual motor carriers’ fleets, including 400 hours of salt-spray testing, our coated rotors demonstrated improved service life over uncoated rotors.”
