What Causes My Car to Shake When I Brake?

What causes a car to shake when you brake? There are several possible causes. Warped rotors, improperly balanced tires, and misaligned wheels are just some of them. If you aren't sure what might be causing this problem, read on to learn what to look for. It's possible your braking system is malfunctioning. However, if you've been experiencing this problem for several months, it's likely something more serious.

Warped Rotors

If you've ever wondered why your brake pedal or steering wheel wobbles when you brake, then it might be time to look at your braking system. Warped rotors can cause your car to shake, causing it to lose traction and slow down. While minor warps won't cause the problem, major warps can cause a car to shake while braking.

The most obvious sign that your brakes aren't working properly is warped rotors. They should be smooth when new and should contact both sides evenly. If you feel that your rotors are too thin, you can try to turn them down slightly. This will reduce the thickness and cause poor heat transfer. If you can't find the warped rotors, however, there is no reason to worry.

Warped rotors are the most common cause of a shaking car. These rotors are round pieces of metal that act as brake pads. They are often hidden under hubcaps but can cause an uncomfortable sensation while braking. And, it's not just the brake pads that are affected, but also the ABS sensors. If this problem occurs regularly, it's time to replace the rotors. Replacement rotors will cost between $300 and $400.

If you are interested in do-it-yourself auto repairs and would like to do your own rotor replacement we recommend scheduling an online mechanic right here on Video Chat a Pro. The live mechanic chat will help you through the car repair and help diagnose the problem.

There are many possible causes for shaking cars. The most obvious one is warped brake rotors. They are the parts of the brake system that clamp down on the brake pad when you apply the brakes. As they wear, warped rotors have imperfections on their surfaces. Warped rotors may have changed shape over time, which can lead to a shaking car. The thickness of the rotor also plays a role in warping. Brake rotors are usually thinner than normal, and thinner ones are more likely to sustain heat than thick rotors.

Improperly Balanced Tires

If you experience vibrations while braking or driving at highway speeds, it's possible that your car's tires are unbalanced. The weights on the wheels shift as you drive, or a bump knocks them off balance and sends the weights flying. Your car may also have unbalanced wheels, which can cause a pulsating or shaking sensation in your steering wheel.

The vibrations you feel in your steering wheel can be attributed to improper wheel balance. To remedy this, you can install small lead weights on the inside of your wheels. These small adjustments can make a big difference when you brake because even small changes in wheel balance can lead to a noticeable shake. If your car shakes when you brake, you may consider getting your wheels balanced, as the process is relatively easy and quick.

Another possible cause of car vibrations is an unbalanced suspension system. Unbalanced tires can cause your steering wheel to shake and make it difficult to steer. Your car's suspension system needs a check-up, so a qualified mechanic can inspect it and fix it. You should rotate your tires every 5,000 to 7,500 miles. You can also check your vehicle's alignment to ensure your wheels are balanced properly.

Misaligned wheels

What causes my car to shake when I brake? Most likely, it's the wheels. Your car may not even shake if your foot is off the brake pedal. If you experience this shaking, it could mean that your wheels and tires are misaligned. Check your rotors to determine which is at fault. If they're warped, you can have them machined or turned straight.

You'll also want to make sure the tires are balanced. Misaligned tires can lead to excessive wear and tear on your car's brakes. Make sure you balance the tires before you do anything. If this doesn't work, you should take your car in for a full alignment. Once you've done that, drive the vehicle around 50 miles or so. Then, take your hands off the wheel and watch for a slight veering. If your car is traveling in a straight line, it's likely it's not an alignment issue. If you notice any shaking, stop the vehicle and get it checked out.

Unbalanced wheels can also cause vibration. These are especially common in vehicles with lightweight suspension systems. Not only will they cause your car to shake when you brake, but they can also damage steering components. When you're driving on uneven roads, the resulting imbalance will knock the wheels out of alignment. Check the tread depth on each wheel to determine if they're out of alignment. If you notice uneven tread, the wheels are out of alignment.

Poorly aligned brakes

If you are experiencing vibrations or squealing when you apply the brakes, the chances are your wheels are out of alignment. Wheel alignment is essential for proper car handling because poor wheel alignment can lead to premature tire wear and damage to vital suspension components. Your car will shake, vibrate, or make a funny sound when braking, so it's best to get your wheels aligned by a qualified mechanic.

Besides poor alignment, bad rotors and worn-out brake pads are common causes of shaky cars. It's important to get your car inspected by a mechanic if you suspect that your car is experiencing this problem. This way, they can accurately diagnose the problem and recommend the proper repairs. In addition to getting your wheels aligned, you should also consider checking your suspension.

Your tires are also another common cause of car shaking. If you experience this while driving and braking, it may be time to get them checked. Improperly aligned tires will make your car feel out of balance, and this will affect your vehicle's alignment. In addition to your tires, you should get them replaced if they are too worn. It may also be a sign of a more serious issue.

If you notice that your car shakes when you brake, it's time to get them checked. You'll probably need to replace them, but if you're experiencing vibrations, it's likely you need a new set of rotors. In this case, you should replace the worn pads, as they won't properly contact the new rotors. You can try replacing them, but make sure you check the alignment of the brake pads and rotors before making any big decisions.

Ask a mechanic online about the possibility of the vibration being caused by your brakes. The online mechanic can also guide you through replacing your own brake pads.

Heat on brake rotors

The reason your car shakes while braking may be due to the condition of your brake rotors. Because the rotors clamp down on the brake pad when you apply the brakes, they can become worn and damaged over time. Moreover, the rotor's thickness plays an important role in warping. Friction between the brake pads and rotors produces heat, which makes the rotor metal brittle.

In some cases, the warping of the rotors could also be the cause of the shaking. If you have noticed that your car shakes when you brake, it could be because your rotors are warped due to the heat. Although warpage is less noticeable once the rotors have cooled down, it can still be very uncomfortable. In such cases, it is advisable to take your car to a service center and have them checked.

Another reason for a shaking car is a worn-out brake pad. Replace your brake pad when you have at least one-quarter left. A high-pitched squeal can indicate that your pads need replacement. Moreover, you may feel light vibrations due to the metal tab on the brake pad. If you notice vibrations while braking, it is most likely due to the rotors.

Incorrectly sized guide pins

A dry guide pin in the brake adapter could be the cause of your car's shaking while braking. Guide pins are tiny cylindrical parts of brake calipers that need to be lubricated and cleaned to ensure proper function. If your guide pins are dirty or dry, you could be experiencing car shaking while braking. Clean the guide pins before reinstalling them.

Another common cause of car shaking is incorrectly sized guide pins. These are part of the brake caliper and are used to guide the brake pad against the rotor. If your pins are dry, your caliper will not function properly and your brake pad may press the rotor at the wrong angle. In turn, the steering wheel will shake when you brake or accelerate.

Besides worn brake pads, worn brake rotors and engine mounts can also be the cause of shaking. If your car is pulsating, talk to a mechanic online or take your vehicle to a local brake shop. Ask a mechanic on Video Chat a Pro to help with the diagnosis options. This way, you will know if your car is due for repair or replacement. In the event that the problem is caused by a seized guide pin, you should consult a mechanic to get it fixed as soon as possible.
