The aftermarket business of ArvinMeritor has released hydraulic disc brake rotors with a new, patented coating called ZXP3, which is designed to protect against oxidation and corrosion.
The new coating will initially be applied to rotors with a cast-in ABS tone ring, while other applications for the coating are under research and development.

The coated rotors will be distributed under the Meritor and Euclid brands through commercial vehicle aftermarket distributors and OE truck dealers in the U.S., Canada, and Mexico starting this month.

Brake rotors are made of iron, and rust is a common problem particularly in the tone ring area. It forms quickly on bare metal and can lead to diminished ABS braking performance, corrosion, and metal fatigue. ArvinMeritor's coating process ensures that the rotor receives a complete application.

"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 for the aftermarket division. "After extensive testing both in the lab and in actual motor carriers' fleets, including 400 hundred hours of salt-spray testing, our coated rotors demonstrated improved service life over uncoated rotors."
