5 Reasons Your Car Shakes When Braking

When you press your foot on the brake pedal in your vehicle, your vehicle should slow down. It shouldn't start shaking as it starts to slow down. If your vehicle is shaking when it is slowing down, that means that something is wrong with your vehicle. There are a few things that can cause this issue.

Warped Brake Rotors

One of the most common reasons your vehicle is shaking when braking is warped brake rotors. When you apply your brakes, the brake pad clamps down on the rotors. This causes your vehicle to stop. If the brake pad isn't applied with even pressure, that can cause the rotors to become warped over time. The longer you use your brakes in this condition, the more warped the rotors will become, resulting in more damage to your vehicle.

Stuck Brake Caliper

Another issue may be the brake caliper for the vehicle. The brake caliper may be stuck and may not be clamping properly to the rotor, or it may not be opening up and allowing for proper clamping. When the brake rotor isn't working well, your vehicle will shake as even pressure isn't being applied to the rotors. A brake caliper malfunctioning on even one of your brakes can cause this to occur.

Trapped Air

It is possible for air to get into your brake lines. When this happens, the hydraulic system that drives your brakes will not work properly, which is another way that uneven pressure will be applied to the brakes, resulting in shaking when you are trying to slow down.

Old Brake Pads

Your brake pads are only designed to last for so long. It is one of the parts on your vehicle that you will have to replace more frequently. Generally, as your brake pads wear down, they are designed to produce a squeaking sound that will let you know that they are worn out and need to be replaced. However, sometimes they may also make your vehicle feel a little wobbly when you are slowing down as well as they wear down.


Finally, the issue may not be with your brakes at all but may be with your tires. If your tires are not properly balanced and aligned and have an unusual wear pattern on them, that could be causing the shaking you are experiencing.

When you apply your brakes, your vehicle should come to a smooth stop. If that is not the case, you will want to take your vehicle to an auto repair shop right away to figure out what the issue is that is holding you back from smoothly stopping your vehicle.
