Disc thickness variation and the myth of warped rotors

Understanding disc thickness variation and why it’s confused with rotor warp Disc thickness variation (DTV) is a brake rotor condition where opposite faces of the brake rotor accumulate an extra thickness of brake friction material or thinness due to uneven wear. When a brake rotor develops DTV it causes brake pedal pulsation during braking. Most people refer to this as rotor warp. But rotors don’t warp. In fact, the braking system on stock cars and trucks can’t possibly generate enough heat to warp a brake rotor. Don’t believe me? See … Read More
