1. Warped Brake Rotor: Overheating or uneven wear can cause the brake rotor to warp, leading to vibrations during braking.
2. Uneven Brake Pad Wear: If the brake pads are worn unevenly, it can cause the wheel to shake when the brakes are applied.
3. Worn or Damaged Brake Caliper: A faulty brake caliper can cause the brake pads to apply unevenly, resulting in shaking.
4. Loose Wheel Nuts: If the lug nuts are not properly tightened, the wheel may shake while driving or braking.
5. Damaged or Worn Steering Components: Worn or damaged tie rods, ball joints, or control arm bushings can cause the wheel to shake when braking.
6. Driveline Issues: In rare cases, driveline issues, such as a faulty driveshaft or CV joint, can cause vibrations that are felt through the steering wheel or front wheels.
7. Misalignment: Improper wheel alignment can also cause vibrations, especially at higher speeds.
Diagnosis and Solution:
1. Visual Inspection: Check the brake rotors for any signs of warping or damage. Inspect the brake pads for uneven wear or any foreign objects that may be caught between the pad and rotor.
2. Test Drive: Take the vehicle for a test drive and pay attention to when and how the shaking occurs. Does it happen only when braking, or does it also occur when accelerating or turning?
3. Professional Diagnosis: If the problem persists or you're not comfortable performing the diagnosis yourself, take the vehicle to a qualified mechanic or repair shop for proper diagnosis and repair.
