Notes
Proper Break-In Procedure for Steel or Cast Iron Rotors
New steel/iron rotors should be bedded in before being used in racing conditions. Proper bedding will prepare the rotor surface, prolong the rotor's life, and make it more resistant to thermal checking or cracking under severe braking conditions. The following procedures should be performed when bedding in both steel and cast iron rotors. It is best to bed in a new rotor using a used set of pads, preferably ones which will not create heat rapidly. Generating heat too rapidly will thermal shock the rotors. Likewise, when bedding in a new set of brake pads it is best to perform the process on a used rotor. This new/used bedding process permits controlled bedding of each individual component.
Make sure rotor surfaces are free from oils, grease, and brake fluid. Run vehicle up to a moderate speed and make several medium deceleration stops to heat up the rotor slowly. This will help reduce the chance of thermal shock caused by uneven heating of the rotor. Pull into the pits and allow the rotor to cool to ambient air temperature. Care should be taken not to ride the brakes into the pits as this may hot spot the rotor causing premature wear to the surface or structural damage.
Info
AFCO continues the commitment to bring new and innovative components to the racing community. Pillar vane brake rotors are engineered to provide superior strength, reduce rotor weight and run cooler. At the heart of the rotor, each pillar is diamond shaped providing brake pad surface stability as well as reducing rotating weight over rotors of similar strength. Racers will take note of reduced weight when compared to rotors of similar strength. Reduced rotating weight means reduced lap times. When brake performance is discussed, AFCO is the bottom line.
- Designed using premium grade alloys for superb thermal shock stability
- Machined and double disc ground to assure precise flatness
- Precise pillar placement for high volume cooling
- Premium center - split castings reduce stress risers
- Rotationally machined balanced - CNC
- More brake pad surface support (pillars) to prevent rotor cupping
- Strength of an 80 vane rotor with the weight savings of a 32 vane rotor
- Machine balanced to reduce vibration
- Increased cooling capacity - allows for trail braking lap after lap
- Drilled to allow gas to escape - improves rotor and pad efficiency
- .810" thick
- 7" bolt circle
- 11.75" diameter
- Weighs 7.1 lbs
