Question- Why should I use cross drilled rotors?

Answer- The primary reason is that cross drilled rotors run cooler, approximately 200-250 degrees, when used with high quality pads. This reduces the chances of warping, which has become a major problem in recent years, particularly on late model U.S. made vehicles. Additionally you will experience improved wet weather braking with shorter stopping distances. If you are experiencing pulsation on the brake pedal, your rotors are warped. It may be possible to turn them, but they will then be thinner and unable to dissipate heat as quickly as before, and will soon warp again.

Power Stop rotors are manufactured by Autospecialty, a subsidiary of TRW, and are used on many law enforcement and emergency vehicles which experience severe braking requirements, and are popular with taxi companies.

Original equipment quality rotors are used as a base stock. Each rotor requires a specific drilling pattern in order not to interfere with the cooling vanes, and this information is programmed and run on a CNC (computer numerical control ) machine. The end result is a brake rotor that is

- mill balanced to prevent vibration

- ground finish that eliminates runout and taper

- double disc ground to ensure parallelism

- non-directional finished

- gold cadmium plated for protection against corrosion ( this does not apply to Hub/Rotor combinations)
