What’s the Difference Between Drilled and Slotted Brakes?

Brake rotors are a fundamental part of a vehicle’s braking system. They’re a simple system, but made up of many different parts. The driver applies the brakes by pressing on the brake pedal, which signals the rest of the braking system, located near the tires. The brake rotor is what the brake pad clamps down on when the driver applies the brakes. The two main types of brakes are drilled and slotted.

What are the differences?

  • Drilled brake rotors:

    • Have holes drilled into them to release heat and gas build-up.
    • Are considered better for driving in wet conditions, as they allow for better water drainage and aren’t as likely to rust.
  • Slotted brake rotors:

    • Have slots cut into, but not all the way through, the rotor.
    • Are more durable, and less likely to break.

The rotors on a vehicle last, on average, from 30,000 to 70,000 miles. A licensed mechanic can evaluate the rotors and advise you on their status. They should not need to be changed as often as the brake pads, but should be replaced in pairs.

Very professional. Was running late from previous job and called ahead to let me know. Worked efficiently. So nice not to have to drive far and sit in a waiting room for hours to get the job done.
Toyota Highlander - Brake Pads Replacement (Front) - Rowlett, Texas
Chuck was great! We talked via phone to discuss the available options to repair my Highlander. He worked with me to schedule a time that was convenient for me, and he arrived early for the appointment. He walked me through some of the other issues that exist on my 2008 Highlander which has 223k miles. His feedback on my car was clear and easy to understand.
