ArvinMeritor’s Aftermarket business, responding to customer demand and an ongoing industry call for more rust-resistant brake components, recently introduced hydraulic disc brake rotors with a new, patented coating, called ZXP3, designed to protect against oxidation and corrosion.
The initial launch will cover three part numbers, with more models to be released throughout the year, said ArvinMeritor. The new coating will initially be applied to rotors with a cast-in ABS tone ring, and 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, 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.”
ArvinMeritor Aftermarket has invested significantly in the development of corrosion-resistant coatings for key components, continuing its commitment to innovations for the aftermarket. Twelve months ago, the company introduced remanufactured brake shoes with PlatinumShield, a unique coating process that protects against micro-abrasion and rust-jacking.
“This is a unique product in terms of performance and value for the customer,” said Terry Livingston, general manager-Americas, ArvinMeritor Aftermarket. “Our ZXP3 coating protects against corrosion yet is priced competitively against other rotors used under the same application. It’s ideal for fleets across the medium-duty spectrum and reinforces our leadership in the development of innovative aftermarket products.”
ArvinMeritor is one of the largest providers of aftermarket brake rotors for medium-duty trucks, buses, delivery vans and other class 2-7 commercial vehicles. Meritor and Euclid coated rotors are backed by a one-year/12,000-mile warranty and the full complement of
