The Truth About Warped Brake Rotors
Debunking the Myth That Brake Pedal Pulsation is Caused By Warped Brake Rotors Any time someone asks about brake pedal pulsation, the answer they hear is that their brake rotors are warped. Let’s do a hard stop right here. But brake rotors DO NOT WARP. Yes, you read that correctly. Brake rotors are not made like vinyl LP records that carp warp in a hot car. Instead, they’re made out of cast iron; iron that’s cast at around 2,300°F. Cast iron doesn’t even begin to soften until it reaches close … Read More
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
