Afco Left Hand Slotted Pillar Vane Hybrid Hub-Rotor Assembly, 10.13

AFCO's new “Pillar Vane” Hybrid hub and rotor program are targeted at Circle Track racing, Open Wheel Modified, Street Stock, Hobby Stock and related classes.  The new hybrid rotor combines the strength of Afco's 1975-’81 Ford style hub with the lighter design of a GM Metric rotor. The “Pillar Vane” rotor technology produces lightest, coolest running and strongest hub and rotor assembly in the industry.  Please note that this slotted rotor is not IMCA approved and when the IMCA approved rotors is required, rotor # 106-6640124 can be utilized.

This new rotor will improve strength, improve cooling, reduce un-sprung weight, reduce vibration, improve traction and increase driver feel and overall brake system performance.

• Pillar Vane design promotes improved pad surface support – no cupping
• Designed for use with 74-78 Mustang II & 74-80 Pinto spindles
• Machine balanced to reduce vibration – improved traction
• Double disc ground for precise flatness
• Improved brake system cooling through usage of pillar design
• Lightest Hybrid rotor-hub assembly on the market
• Available in slotted design
• Designed for use on left hand side
• Proven by top chassis builders and racers Nationwide
• 5/8" Coarse Studs on 5" x 5" Pattern
• Not approved for IMCA use

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.
