A car shakes when braking mainly due to issues with the braking system or related components. Common causes include:
- Warped or worn brake rotors: Brake rotors can become warped from heavy or aggressive braking, causing uneven contact with brake pads, which leads to shaking or vibration during braking. This is often felt in the steering wheel.
- Unevenly worn brake pads: When brake pads wear unevenly, they exert uneven pressure on the rotors, causing vibrations.
- Brake caliper problems: Stuck or malfunctioning brake calipers can apply uneven pressure causing shaking and pulling to one side during braking.
- Tire issues: Worn, unbalanced, or damaged tires can cause shaking which becomes more noticeable when braking.
- Suspension or wheel bearing problems: Worn suspension parts or loose/damaged wheel bearings can lead to shaking when braking due to instability in wheel movement.
In summary, shaking during braking is often caused by warped rotors, uneven brake pad wear, or brake caliper problems. It can also be related to tires, suspension, or wheel bearings. It's important to get the braking system inspected and serviced to ensure safe and efficient stopping.
