Brake rotors come in many different types. Before you can purchase a fresh set of brake rotors, you must understand each of these different types, what sets them apart, and what are the pros and cons of every style. The four kinds of brake rotors are:
Drilled Only – Drilled brake rotors are easy to recognize because they have a series of holes drilled into the metal.
Slotted Only – Slotted rotors have slots, which look like lines in the metal.
Drilled & Slotted – Drilled and slotted brake rotors combine the drill marking and slot marking.
Blank or Smooth – As the name suggests, blank or smooth brake rotors have a smooth or plain surface, with no holes or markings in the metal.
One of the most important components of high-performance brake pads is their ability to dissipate heatIf the brake pads get too hot, the brakes will fade — often boiling the hydraulic brake fluid in the process. Brake fade occurs when braking components get too hot, resulting in a loss of stopping power.
