1. Warped Brake Rotors: Warped brake rotors can cause the steering wheel to shake and the brake pedal to pulsate when braking. This can be caused by uneven wear and tear on the rotors, excessive heat, or improper installation.
2. Brake Pad Issues: Worn-out or damaged brake pads can also cause the steering wheel to shake and the brake pedal to pulsate. If the brake pads are not making proper contact with the rotors, it can cause uneven braking and vibrations.
3. Wheel Alignment: Improper wheel alignment can lead to uneven tire wear and cause the steering wheel to shake and the brake pedal to pulsate.
4. Tire Issues: Uneven tire wear, bulges, or sidewall damage can also cause the steering wheel to shake and the brake pedal to pulsate.
5. Suspension Problems: Worn-out or damaged suspension components, such as control arms, ball joints, or tie rods, can cause the steering wheel to shake and the brake pedal to pulsate.
6. Driveline Issues: Problems with the driveshaft, universal joints, or wheel bearings can also cause vibrations and pulsations in the steering wheel and brake pedal.
To diagnose the exact cause, it's important to have your vehicle inspected by a qualified mechanic. They will be able to identify the source of the problem and recommend the necessary repairs. It's not recommended to drive with these symptoms as they can compromise your safety and lead to further damage to your vehicle.
