What Causes a Shaking Steering Wheel When You Brake?
There are several reasons why your steering wheel might start shaking when you brake. Here are some of the most common causes:
Worn-Out Brake Pads
One of the most common causes of a shaking steering wheel when you brake is worn-out brake pads. When brake pads wear down, they can cause the brake caliper to move unevenly, leading to vibrations in the steering wheel. If your brake pads are worn out, you may notice other symptoms such as a spongy brake pedal or a grinding noise when you press the brake pedal.
How to Check Your Brake Pads
To check your brake pads, you’ll need to lift the hood of your vehicle and look for the brake caliper. The brake caliper is usually located on the back of the wheel hub, and it’s attached to the brake rotor. You can check the brake pads by looking for signs of wear, such as cracks, wear marks, or excessive dust buildup. If you’re not sure how to check your brake pads, you can consult your vehicle’s owner’s manual or take your vehicle to a mechanic.
Unbalanced Wheels
Unbalanced wheels can also cause a shaking steering wheel when you brake. When wheels are out of balance, they can cause vibrations in the steering wheel, which can be especially noticeable when you brake. Unbalanced wheels can be caused by a variety of factors, including worn-out tires, uneven tire wear, or damaged wheel bearings.
How to Check for Unbalanced Wheels
To check for unbalanced wheels, you can perform a simple test. Drive your vehicle at a steady speed and press the brake pedal. If the steering wheel starts shaking or vibrating, it could be a sign that your wheels are out of balance. You can also check for unbalanced wheels by looking for signs of uneven tire wear or by using a tire balancer.
Loose or Worn-Out Steering Components
Loose or worn-out steering components can also cause a shaking steering wheel when you brake. Steering components such as the steering rack, steering pinion, or steering idler can wear out over time, causing vibrations in the steering wheel. Loose steering components can be caused by a variety of factors, including worn-out ball joints, loose steering tie rods, or damaged steering columns.
