Centric Parts Opens Friction Lab to Enhance Research and Development Program
Industry, Calif. (October 20, 2014) – Centric Parts, North America’s leading manufacturer and supplier of aftermarket brake, clutch and chassis components, has today announced the opening of a state-of-the-art Friction Materials Lab at the company’s Compton, California facility.
StopTech Sport Rotors are 1-piece, slotted, drilled or drilled+slotted direct replacement rotors for your factory brake system and stock calipers. StopTech Sport Rotors offer improved cooling as well as other advantages the competition doesn't offer.
Introduced in 1998, these rotors were the backbone of the first premium replacement brake rotor program in North America. Innovations within the program incude E-Coating, full machining, mill balancing and symmetric split core castings, as well as the availability of directional vanes, cryogenic treatment and the use of Power Alloy in most applications. Today, StopTech Sport Rotors are available for more than 2500 vehicle applications all machined in Centric's California manufacturing center. Every StopTech Sport Rotor is a direct replacement for a factory brake rotor, allowing the retention of factory calipers in the system.
StopTech Slotted Sport Rotors StopTech Sport Rotors are premium quality replacement brake rotors that feature a signature "short slot" design. The slot improves brake system performance by wiping away the debris of used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and helps prevent pad glazing. The edges sweeping the pad slightly increase the effective coefficient of friction or "bite," amplifying brake system response to pedal input. By providing an escape path for water, slotted rotors can also improve initial brake response under wet conditions.
Power Alloy metallurgy is another unique feature in many of the StopTech Sport Rotors. Quality and performance live inside the rotor too. Choosing the correct foundry partner and working to improve the metallurgy are all part of Centric's continuous improvement process that helps to reach established targets for hardness and tensile strength. Many of Centric's top-selling part numbers are cast using this Power Alloy iron specification, an enhancement in the carbon and molybdenum content of the iron. Carbon and molybdenum improves crack resistance and reduces noise, vibration and harshness (NVH).
StopTech Sport Rotors are also available with an optional cryogenic treatment. Although cryogenic treatment is invisible to the naked eye, many fleet customers are sold on its ability to extend the service life of the brake rotor. Deep cryogenic treatment is a one-time process that permanently improves the performance and wear characteristics of metal components, from brake rotors and engine parts to machine tools and gear sets. Using a proprietary, computer controlled process, the metal is cooled to -300oF before gradually being heated to +300oF, and then slowly returned to room temperature as the final step. All new StopTech Sport Rotors may be ordered with cryogenic treatment for an additional fee.
Machined Finishes StopTech Sport Rotors feature 100% fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component. In addition, StopTech Sport Rotors are inspected for balance and mill-corrected to a tolerance of less than 2oz. per inch
Center-split core castings provide proper heat transfer and thermal efficiency, resulting in superior braking power and safety.
Directional Vane Designs
Most StopTech Sport Rotors match the original factory cooling vane design. In the most popular sports car and light truck applications, Centric has improved the design by using directional vanes to improve cooling. This represents a distinct upgrade from the original equipment rotors, which usually feature a straight or pillar vane design. The directional vane is a more efficient air pump providing increased resistance to brake fade and faster thermal recovery to temperature spikes generated by aggressive or repeat stops.
StopTech Sport Rotors are mill balanced to a tolerance of less than 2oz. per inch. This additional machining operation reduces feedback associated with rotor vibration and provides a smooth confident application of braking force.
