Installation Tips

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.

Overall Assessment

Customers appreciate that the product fits perfectly and is the correct size for older chassis, offering an advantage over competitors. They note the product's light weight, the pre-installed studs, and easy installation, especially with a bearing kit. Users confirm our product works well and is ideal for replacing broken parts. Compared to other products, ours stood out for the practicality and quality. However, customers warn that users must maintain the alignment of the calipers, as the mounting brackets can bend. Overall, the product is highly recommended for its quality and usability.

Great out of the box rotors for pinto spindles. Already pre-drilled with 5/8 studs already installed. Along with the bearing kit, these are an easy installation.

Rotor works well, but you must keep the alignment of the calipers straight, the mounting brackets are prone to bending.
