What Causes Brake Rotors to Warp?

Brake rotors work alongside brake pads to stop or deaccelerate a car. When a driver steps on the brake, the brake pads clamp on the rotors, and through friction, they produce the desired effect. With time, the heat produced leads to uneven surface wearing of the brake rotors.

This scenario is called warping. Extremely warped brake rotors are ineffective and jittery. But this condition is not as serious as other brake defects. With that in mind, here are some factors that cause brake rotors to warp.


As we've mentioned earlier, heat is a precursor to warped brakes. Whenever the surfaces of two moving parts come into contact, friction and heat is produced. And the working of the brake relies on the friction force produced between the brake rotors and pads. The heat produced on the surface results in brake rotors warping.

Manufacturing Defects

Brake rotors that don't meet industry standards warp easily. Some of the manufacturing defects include but are not limited to the use of incorrect material or imperfections on the surface.

Frequently Driving on Rough Roads

Driving over potholes, speed bumps, or on rough road induce a lot of stress on the rotors. With time, these forces lead to uneven wear of brake rotors. Also, when driving over rough roads drivers tend to brake frequently making the rotors susceptible to wear.

Improper or Inadequate Maintenance

When brakes are working, debris and dirt build up between the pads and the rotors. If this dirt is not regularly cleaned during scheduled maintenance it leads to brake rotor warping. Additionally, during routine maintenance, worn-out and thin brake pads should be replaced. Thin pads are ineffective in heat dissipation a scenario that leads to warping.

Always remember most of the above causes of warping can be avoided by taking good care of your vehicle. If you need brake repair, welcome to Fox Run Auto in Bear, DE today!
