1. Warped Brake Rotors: If the brake rotors are warped or uneven, it can cause the steering wheel to shake or vibrate when the brakes are applied.
2. Worn Brake Pads: When brake pads are worn down too much, it can cause the brake rotors to overheat and warp, leading to vibrations and shaking.
3. Damaged Wheel Bearings: Worn or damaged wheel bearings can also cause the steering wheel to shake when braking.
4. Loose or Worn Suspension Components:** Worn suspension components such as ball joints, tie rods, or control arms can cause the vehicle to shake while braking.
5. Misaligned Wheels:** If the wheels are not properly aligned, it can cause uneven tire wear and affect braking performance, resulting in shaking or vibration.
6. Uneven Tire Wear:** Different tire wear patterns can affect the vehicle's balance, causing shaking while braking.
7. Brake Caliper Issues:** If the brake calipers are not functioning correctly or are sticking, it can put uneven pressure on the brake rotors and cause shaking.
8. Faulty Brake Lines or Hoses:** If the brake lines or hoses are damaged or clogged, it can affect brake fluid pressure, leading to vibration during braking.
To determine the exact cause of the shaking, it's recommended to have the vehicle inspected by a qualified mechanic who can diagnose and fix the issue. Ignoring or delaying the repair can compromise braking performance and safety.
