BRAKE ROTORS
Can You Stop?
Addressing a need in Formula SAE and the small formula car market, Kaz Technologies has introduced cast iron brake rotors. These rotors have been blanchard ground to our specifications and can be easily machined to fit your application and design. Purchasing ground blanks allow you to be creative with weight reducing and cooling channels.
Have you ever not passed brake tech, or were unable to lock your wheels?
Because of its availability, many FSAE teams have tried conventional steel for brake rotors. What they have found is unacceptable braking characteristics. This is because most racing brake pads are designed to work with cast iron brake rotors. Kaz Technologies uses Dura-Bar G2 cast iron, a material commonly used for motorcycle, OEM, and racing brake rotors. With the Kaz Technologies cast iron rotors, your choice of brake pad will now work properly and stop the car!
No more fear of failing brake tech! No more driver complaints of having no brakes!
Material Specification:
Kaz Technologies brake rotors are cast from Dura-Bar G2 Cast Iron. This is an engineered, gray cast iron for specific property enhancements. It is a pearlitic gray iron with flake graphite.
- Dura-Bar G2
- Conforms to ASTM A48 Class 40, (SAE J431 G12, was G4000).
- Tensile strength ˜ 40 KSI [272 MPa].
- Brinell Hardness = 183-301.
- Thermal Conductivity ˜ 370 BTU-in/hr-ft^2-DegF [53.3 W/m-K]
Why Use Cast Iron:
MYTH - RACING BRAKE DISCS ARE MADE FROM STEEL by Carroll Smith
To digress for a moment "steel discs" are a misnomer frequently used by people who should know better. This group includes TV commentators and drivers being interviewed. Except for some motorcycles and karts, all ferrous discs are made from cast iron - an excellent material for the job. While steel has a higher tensile strength, cast iron is many times stronger than disc brake requirements. Its thermal transfer characteristics are significantly better than those of steel so that the heat generated at the interface between pad and disc is efficiently carried through the friction faces to the interior surface of the disc and into the vanes from where the heat is dissipated into the air stream. Cast iron is more dimensionally stable at elevated temperature than steel and is a better heat sink - so let us hear no more talk of "steel" brake discs.
