Why Does My Car Vibrate When I Brake?

Your vehicle’s braking system is the most important safety system in your vehicle, responsible for providing the right amount of friction to bring you to a controlled stop. So when you hit the brakes and notice unusual vibrations, it can be concerning knowing this vital system is experiencing issues.​

In this article, we’ll cover how the brake system operates, why these vibrations may occur, and how to prevent these symptoms in the future.

​How Do Brakes Work?

Most modern vehicles employ a disc brake system, which consists of a large metal rotor, a hydraulic caliper, and an abrasive brake pad on each wheel. When you hit the brakes, this pressure is transferred, either electrically or hydraulically, to the brake calipers, which press the pads against the rotors with immense force, producing friction to slow each wheel.

Why Are My Brakes Causing Vibrations?

Vibrations caused by brake issues are some of the most frequent symptoms of rotors that have been warped.

Repeated friction during braking generates significant heat within the metal rotors. Over time, this thermal energy can cause the rotors to warp or become slightly deformed. Even if the rotor’s surface appears intact, a warped rotor creates an uneven surface that causes the brake pads to “hop” or pulsate as they make contact, resulting in noticeable vibrations.

If you suspect your brake rotors are warped, it’s crucial that you have your brake system inspected and repaired as soon as possible to avoid potential brake failures and unsafe circumstances down the line.

How to Prevent Warped Rotors

Here are a few tips you can use to protect your brake rotors from deformation:

Good braking habits: Slowing down gradually to avoid putting excess strain and heat on the rotors, as overheating is the primary cause of warped rotors.

Regular Brake Maintenance: Having your brake fluid replaced will ensure your brake calipers and the pads and rotors will always receive the proper pressure for safe braking.

Swap Out Brake Rotors: While rotors are built to last, it’s a good idea to have yours swapped along with the pads between every 35,000-60,000 miles. The exact interval will vary based on the type of brake components, driving habits, and surrounding weather.
