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.

These rotors are most often directly mounted to "fixed" mount hats or mounting plates, but they can also be used with special dynamic mount hats or plates that require the use of a standard hole mount disc. Each rotor size is available in the standard solid plate style, or weight drilled for lighter duty applications.
Willwood brake hats have a long standing reputation for fit, performance, and durability. Manufactured from premium grade aluminum alloys offering high strength and low weight.
