The shaking of the steering wheel when braking is typically caused by issues related to the brake system or tires. Here are the most common causes:
- Warped or Warped Brake Rotors: When brake rotors become uneven or warped, the brake pads cannot maintain consistent contact, causing vibrations that you feel through the steering wheel during braking. This is often the most common reason for the shaking.
- Worn Brake Pads: Old or dirty brake pads can cause uneven contact with the rotors, leading to pulsation and shaking when braking.
- Unbalanced or Worn Tires: Tires that are unbalanced or worn unevenly can cause the steering wheel to wobble, especially noticeable when braking.
- Brake Calipers Issues: If brake calipers do not press the brake pads evenly against the rotors (due to wear, corrosion, or sticking), this can result in vibrations.
- Suspension Problems: Worn suspension components like control arms or ball joints can lead to instability and shaking when braking.
- Improper Installation or Alignment: Poor installation of brake rotors or wheels can cause imbalance and uneven braking surfaces, leading to vibrations.
To fix the shaking steering wheel when braking, it is generally recommended to:
- Inspect and possibly resurface or replace warped brake rotors.
- Replace worn brake pads.
- Check and balance tires.
- Inspect brake calipers for proper function.
- Check suspension components for wear.
- Ensure proper installation and wheel alignment.
Driving with a shaking steering wheel when braking can be dangerous, so it’s best to have a trusted mechanic inspect and repair the issues promptly.
