Four Types Of Brake Rotors
- Blank - Features a smooth surface
- Drilled - Offers multiple holes drilled into the surface of the rotor for better "bite"
- Slotted - Has the appearance of smooth grooves that cover the diameter of the brake rotor
- Drilled and Slotted - Offers the benefits of both drilled and slotted brake rotors combined in one
Most OEM factory installed brake systems use a blank rotor. But some high-performance cars or heavy-duty trucks use slotted and drilled brake rotors. Slotted grooves or drilled holes are used to vent heat away from the brake pad. As the rotor spins, heat build-up escapes. By removing extra heat the brakes may perform better under challenging conditions.
6 Reasons To Choose A Blank Smooth Brake Rotor or OEM Brake Rotor
- Most common brake rotor used by most car manufacturers
- Very cost-effective
- Preferred by "around town" luxury car drivers and long-distance endurance racers
- Quiet - smooth blank brake rotors produce very little street noise or rumble
- Produces very little brake dust but may increase brake pad glazing
- Lasts longer than other brake types
6 Reasons To Choose Drilled Rotors
- Great for general use in street vehicles
- Best known for performing well when raining because drilled holes give the water a place to escape
- Holds up well over the life of the brake rotors
- Delivers more friction causing the brake rotor to dry off quickly in wet conditions
- Wears unevenly and may require frequent maintenance
- Develops cracks when used for racing because the brake rotor cannot withstand repeated heat and cool cycles
