What Are the Slots on Brake Rotors For?

Brake rotors are typically made from a number of different materials, including cast iron, steel, and aluminum. The material used in the rotor affects the braking performance in different ways. Cast iron brake rotors are the cheapest option and offer the poorest braking performance. They heat up quickly and stop working properly when they get too hot.

Steel brake rotors are more expensive but offer better stopping power and durability. They also cool down faster than cast iron rotors, but they can still be too hot to use in some cases. Aluminum brake rotors are the most expensive option, but they offer the best braking performance overall. They don’t heat up as quickly as steel or cast iron rotors, and they remain cool to the touch even after extended use.
