Why Does My Car Shake When I Brake?

If your car shakes when you press the brake pedal, it can be unsettling. This shaking, or vibration, is usually a sign that something isn’t right with your braking system or other related parts of your car. Below, we’ll explain the most common causes of this issue and what they mean.

What Causes a Car to Shake When Braking?

Several factors can cause a car to shake when braking. Understanding these factors can help you take the necessary steps to address any shaking issues and maintain your vehicle’s safety and performance.

Warped brake rotors

Brake rotors are the discs that your brake pads press against to slow down your car. Over time, these rotors can become uneven, or “warped,” due to heat and wear. When this happens, the brake pads can’t grip the rotors evenly, causing your car to shake as you brake.

Worn brake pads

Brake pads wear down with use. If they become too thin or damaged, they may not contact the brake rotors smoothly. This uneven grip can lead to vibrations when you brake. If your pads are worn, you might also hear a squealing noise.

Suspension problems

Your suspension system keeps your ride smooth, even when you brake. If parts of the suspension, like ball joints or tie rods, are worn out, they can cause shaking when you apply the brakes. These issues usually require a mechanic to inspect and fix.

Tire issues

Sometimes, the problem isn’t with your brakes at all — it could be your tires. If your tires are unevenly worn, misaligned, or not properly balanced, you might feel vibrations when braking. Checking your tires regularly can help prevent this.

Brake caliper problems

The brake calipers squeeze the brake pads against the rotors to slow your car. If a caliper sticks, it can apply uneven pressure on the rotor, causing the car to shake. This problem can get worse over time, so it’s important to have it looked at quickly.

What Should I Do If My Car Shakes When I Brake?

If your car shakes when you brake while driving on the road, safety should be your first priority. Find a safe spot to pull over as soon as you can and brake gently to avoid causing more shaking or losing control.

Take a moment to check for obvious issues, like flat tires or smoke from the brakes and if you notice anything unusual, do not drive the car.

Call for help, like a tow truck or roadside assistance, to get your car to a mechanic. They can inspect your vehicle and determine what’s causing the shaking.

What Happens If I Ignore the Shaking When Braking?

If you ignore the shaking when braking, the problem can get worse over time. The shaking could be a sign of worn brakes, bad tires, or other issues that may lead to more damage. Eventually, this could make it harder to stop your car safely and even cause brake failure, putting you at risk for an accident. 

Is It Safe to Drive If My Car Shakes When I Brake?

No, it’s not safe to keep driving if your car shakes when you brake. In some cases, it could lead to your brakes failing, which can be dangerous. It’s best to get your car checked by a mechanic as soon as possible.

Summary

By understanding the common causes and getting your car checked by a mechanic, you can ensure a smoother, safer ride and prevent costly repairs down the road. Don’t wait—take care of the issue as soon as you notice it to keep your car running smoothly.
