MCHENRY, Ill. -- Affinia has announced availability of the R-300 Performance Rotor from Raybestos, a member of the Affinia family of brands. According to the company, the R-300 delivers improved pedal feel, lasting rust prevention and increased pad life.
      
The rotor's “S-Groove” slot design provides better pad-to-rotor contact to improve pedal feel and reduce brake fade, according to the company. And, Affinia says, since this design also improves out-gassing, the S-Groove slots can also increase pad life by up to 30 percent.
      
“You can really feel the benefit of the new S-Groove slot design,” said Georgianne Dickey, Raybestos brand marketing manager, Affinia Global Brake & Chassis. “Drivers experience stronger bite without having to sacrifice smooth braking.”

The company says this improved pedal feel is due to maximized pad-to-rotor surface contact. Brake fade is reduced due to improved out-gassing, and the rotor delivers superior “panic-stop” braking thanks to its high-flow, clog-resistant vane design, according to Affinia. The rotor is also less prone to cracking; a problem that takes place on traditional drilled rotor designs, the company said.
      
“The ‘S-Groove’ slot design has been proven on a dynamometer to allow simultaneous out-gassing on both the leading and trailing ends of the friction,” said Rick Woodside, director of product development, Raybestos Rotors and Drums. He said that the rapid inward circulation of air moves gases and particulate matter with centrifugal force to the outside of the rotor; allowing for constant escape of harmful heat and gasses.
      
The metallurgy used in the R-300 Performance Rotor also produces improved performance. The high-carbon damped iron metallurgy has a better rate of thermal conductivity to drastically improve heat dispersion to cancel vibration.
      
The R-300 Performance Rotor incorporates two corrosion-resistant coatings formulated for optimal cooling and premium rust protection. The protective Black Fusion coating is applied to every rotor hat to prevent premature rusting. The corrosion-resistant Grey Fusion coating is proven to withstand more than 300 hours of saltwater exposure (as proven by salt spray test regulation ASTM-B117). It also ensures the rotor edges and vanes remain clear of rust for optimal airflow and cooling. Since these protective formulas cover the entire surface of the rotor, drivers can count on a premium appearance throughout the life of the rotor, Affinia says.
      
As an added benefit to technicians, the non-directional rotor design eliminates the need for unique right and left part numbers. The company notes that the rotors can be used on all four corners of the vehicle, which simplifies ordering and installation.
