How To Check If My Brake Rotor Is Warped
Measuring the brake rotors for minimum thickness on both the front and rear brake rotors will show if your brake rotors are warped. A front brake rotor that has an uneven surface will cause the steering wheel to shake when we brake. The rear brake rotor will only cause a pulsation in the brake pedal if its warped. Here is how to measure the thickness of your brake rotors and check if its warped:
Problems With Brake Rotors And Pads
If your brake rotors are worn out or the brake pads are characterized by uneven wear, both of those problems could cause your vehicle to shake as it slows down. When brake rotors are too worn and in need of repair, the heat that is naturally generated due to braking changes the rotors normally flat surface into one with markedly uneven areas. Similarly, if the brake pads are excessively worn, they cant consistently make contact with the rotors.
You can be a responsible car owner by looking at your vehicles wheels and checking the visible parts of the rotors and brake pads. Ideally, the rotors should not have cracks or grooves, and the pads should show even wear with an adequate amount of the pad material remaining. If you see something different upon inspecting your brake pads, make an appointment at an auto shop so a mechanic can check your cars brake functionality.
What Does It Mean When Your Car Shakes
You probably already know that your car has multiple systems and complex components that keep it running. If one of those systems isnt working correctly, you might see it, hear it, or in the case of car shaking feel it! There are many parts and pieces that when not working properly can cause your vehicle to shake. Paying attention to when, where, and how your car shakes can help diagnose the issue.

Car Vibrates At Certain Speeds
There could be various reasons why tires vibrate, from low air pressure to wheel misalignment. Although your tires look perfectly fine, a simple tire rotation and balance may be necessary for a smooth ride.
If your car is vibrating between 40 and 60 mph, it may be a sign that your tires need to be balanced. Driving with an unbalanced tire can cause steering wheel vibration, and visible signs of wear will develop prematurely on one side of the tire.
In manual vehicles, the most common cause of vibration is the clutch. When you depress the clutch pedal, it disengages the flywheel from the rest of the drivetrain, allowing you to switch gears.
If a manual vehicle is vibrating, this could mean that something is rubbing against a part of your clutch or that there is a problem with your clutch disk.
Solutions For A Steering Wheel That Shakes When Braking
The first step in finding a solution for a steering wheel that vibrates during braking is to determine the cause of the shaking. As we mentioned, this is almost always caused by a problem with the rotors. Other causes of a vibrating steering system would generally cause shaking all the time, not just when braking. With that in mind, we’ll focus this section on the most common rotor problems and their solutions.
One possible cause of vibrations in a car’s wheel is an uneven tightening of the rotors. In that case, you should get yourself to a mechanic who knows how to tighten in a star pattern . This is an elementary concept that any mechanic worth his or her salt should know. Most will also have a torque stick to measure the tightness of the seal. Keep in mind that every car has its own standard torque specifications, which are generally printed on the rotor itself.
More often, a steering wheel that shakes when braking is caused by warped rotors, which your mechanic may be able to diagnose with a simple test — that is, by spinning the rotors by hand to feel for imperfections. A rotor in good working order should move freely and make a complete revolution without any bumps or signs of resistance areas. If you or your mechanic does notice these issues, you’ve probably got yourself a rotor problem.
If your car has received a diagnosis of bad rotors, you might be wondering how urgent a problem this is. It depends on a few factors, which we’ll address in the next section.

Why Is My Car Shaking When I Apply The Brakes
Getting your car to move is important but it is equally important that your vehicle be able to slow down and come to a stop. So, if your car starts shaking when you press down on the brake pedal, its understandable that you would be concerned and want to be assured your safety is not at risk. Here is an in-depth look at this common car issue:
First, keep in mind that car vibrations may seem to originate due to braking, but they also may be caused by wobbly wheels or faulty tires. If you are fairly certain the brakes are to blame, there are several possible issues. For example, if the problem starts soon after you change the tires, it may be due to loose lug nuts. They need to be fully tightened to prevent the wheels from coming off.
No : Low Transmission Fluid
If the level of transmission fluid dips too low in your car, it might start shaking as you accelerate. While this is fairly easy to resolve, it needs to be tended to promptly. If theres a leak and you continue driving with too little transmission fluid, it can permanently damage your cars transmission. That can lead to costly repairs, rebuilds or even replacements, depending on the extent of the damage.
If the car makes a loud noise when it shakes, it could be a sign that the transmission or the drive train could be wearing out.

Steering And Suspension Components
typically, worn steering or suspension components will cause a vibration while driving, not just when braking. however, in some instances a worn or damaged component, such as a loose control arm or damaged knuckle, may cause a vibration when braking. a bent or otherwise damaged axle shaft can have the same effect.
solution: have the car inspected and replace any worn or damaged suspension or steering components. you may need a wheel alignment, as well.
Unbalanced Tires On The Rim
An unbalanced tire is another reason for increased car vibrations.
Knowing how to balance the tires on the wheel rim needs a lot of attention. It is true because tires determine comfort while driving is your can. You dont want to drive your car while jumping up and down.
Ensuring the tire balance not only reduces vibrations but also saves other parts of the car. in the same way, it makes the tire has an even wear. Again, it ensures protection to the rim by not putting a lot of strain on the brake disc.
These and many more are possible causes on why the car shakes while braking. How do you fix them? Here is how:

Car Shakes When Driving Over 70 Mph
When your car starts shaking at high speeds, generally over 70 mph, it is often a sign that you are experiencing one of these common problems.

Car Shaking When Idle
A car will shake when idle when the engine isnt running smoothly. Depending on the specific cause, some shaking can be more severe than others. You may also notice or feel the revolutions per minute randomly changing.
Due to greater engine load and lower engine speeds, rough idle is usually more pronounced in Drive when sitting at a stop light. Consequently, higher RPM when idling in Park can help smooth out a rough idle. Depending on the severity of the problem, you may also experience stalling or backfiring.
What to do?
A smooth-idling engine indicates your engines air fuel mixture, fuel, ignition and emission systems are working exactly right. If thats not the case:
- Check, inspect and replace a dirty air filter and PCV valve that can starve the engine of air or fuel.
- Check for vacuum leaks.
- Replacing worn spark plugs, defective or damaged ignition coils, ignition wires or the distributor cap all DIYable fixes.
A dirty fuel filter or clogged fuel injectors can also cause rough idling and shaking.
- Try replacing the fuel filter and add fuel injector cleaning treatment to your fuel tank yourself. Filters are inexpensive and easy to swap out. Check your owners manual and be sure to replace filters and spark plugs at the manufacturers recommended intervals.
- If this doesnt fix the shaking, its time to bring your car in for service.
Wheel Alignment Out Of Spec
Another potential cause of the vibration can be the wheels being out of alignment. Usually if this is the case, youll notice a vibration through the steering wheel while at highway speeds. Essentially, the front wheels are not pointed straight, and this causes the tires to slightly skip along the pavement while driving. Another symptom will be that the car wants to veer either left or right when your hands are off the wheel. High speeds will make the issue more apparent, and the vibration can become even more severe when braking, as more pressure is being pushed down on the front end. Not only is it dangerous, but it can cause your tires to wear out abnormally fast and unevenly.
Something as simple as hitting a bad pothole can cause your alignment to be knocked out of spec. If you notice this issue, be sure to take it to an alignment shop, and theyll get you straight again. If you fail to fix the issue in a reasonable amount of time, youll be forced to buy some new tires, and you risk additional wear to other parts.

My Car Shakes When I Drive Fast
We’ve discussed your car shaking while braking, but what if your car shakes when your foot is nowhere near the brake pedal? If this sounds like your situation, you may have misaligned wheels or improperly balanced tires. Typically, you can tell which of the two issues is to blame depending on where you feel the shaking. If the shakes come from the steering wheel, your car likely needs an alignment check and service. If they come from the floorboards and seats, a tire balance may be needed.
While wheel misalignment happens when suspension components are not properly angled, tire imbalance occurs when the weight of your car isnt properly distributed on all four tires. Such improper weight distribution can lead to excessive shaking, especially when you drive above 55 mph. To make matters worse, imbalanced tires can wear out prematurely, creating dangerous driving conditions that can only be remedied with entirely new tires.

Can Bad Alignment Cause Vibration
Yes, bad alignment can cause vibration. Also, worn tires, out-of-round tires and improper balance can contribute to shaking, shimmy and vibration. If necessary, rotate your tires to more even tread wear.
Once alignment is off, the tires will start to wear unevenly and cause severe vibration throughout the car. However, its not a good idea to choose alignment as the main reason for vibration until every other possibility has been ruled out.
