Steering wheel shakes when braking
Below are some of the reasons why the steering wheel shakes due to the braking system. This problem occurs when braking.
1) Brake disc (worn brake disc)
- If your steering wheel shakes violently when you brake, the disc may be warped or worn out.
- If grinding the disc doesn’t help or there isn’t enough material left, you will need to replace it with a new brake disc.
- If your steering wheel starts to shake when you apply force to the brake pedal, it may be a sign that your brake rotors are failing. Of course, if your steering wheel shudders only at certain speeds, there could be a variety of reasons (see above). But if it only happens when you press the brake pedal, it’s more likely that your brake discs are the problem.
Every time you put your foot on the brake pedal, the brake pads tighten, putting pressure on the discs as they turn, slowing your vehicle down. But if the discs are worn or installed incorrectly, they can cause the brake system calipers to vibrate.
When this happens, the vibrations are transmitted to the steering wheel via components connected to the brake calipers. As a result, your steering wheel will vibrate every time you press the brake pedal.
People who drive with both feet are at higher risk of developing rotor problems because they may “sit on the brakes”, which can lead to premature rotor wear.
2) Brake Pads (Symptoms of Worn Brake Pads)
As you know, the front braking system is connected to the steering knuckle, which is connected to the end of the steering rack, which is connected to the steering column, and finally to the steering wheel.
So if the rotors are still in good condition, the likely cause of steering wheel vibration when braking is often unevenly worn brake pads themselves or a misaligned brake caliper.
3) Brake Calipers (Stick Calipers)
Broken or stuck brake calipers can also cause vibration, but usually only occur in older cars. In this scenario, the steering wheel starts to vibrate around 50 mph, followed by a burning smell. It’s best to stop the car and not drive it until the problem is fixed.
How to Diagnose Steering Wheel Vibration
Step 1) Identify the Condition
Pay attention to when the vibration occurs. Does it occur at low speeds, high speeds, when braking, cornering, or going straight? This information will help you narrow down the possible causes.
Step 2) Check the tires
Check the tires for low pressure, uneven wear, or any kind of damage. Rotate the tires to see if the wobble changes. If so, a tire balance or wear problem may be the cause.
Step 3) Check the wheels
Check the wheels and rims for visible damage. Jack up the car and spin each wheel to check for wobble, which may indicate a bent rim or worn wheel bearings.
Step 4) Test the brakes
If your steering wheel shudders primarily when braking, listen for pulsation in the brake pedal, which may indicate a warped rotor or caliper.
Step 5) Inspect the suspension components
Check the suspension parts for looseness or wear, especially tie rod ends and ball joints. Any play in these components can cause vibration problems.
STEP 6) CONSIDER RECENT MODIFICATIONS
Think about any recent work that has been done to your car or any accidents it’s been involved in. New tires, a recent wheel alignment, or minor sheet metal damage can all cause vibration issues.
STEP 7) TEST DRIVE
Drive your car on a safe, straight road. Gradually increase your speed, noting at what point the vibrations start or increase. This will help you identify any speed-related issues. Having a second person in the car with you can help, as they can hear the problem better near the passenger side.
Step 8) Get a Professional Diagnosis
If you can’t identify the problem, or you don’t have the tools or expertise to fix it, schedule an appointment with your local service center or independent mechanic. They can run a more thorough diagnosis and ultimately fix the problem.
