1. Warped rotors: Warped rotors can cause a shimmy or vibration when braking. This is because the uneven surface of the rotors causes the brake pads to grab and release unevenly, which creates a vibration.
2. Faulty brake pads: Worn or damaged brake pads can also cause a shimmy or vibration when braking. This is because the brake pads are not able to grip the rotors properly, which can cause them to slip and chatter.
3. Faulty wheel bearings: Worn or damaged wheel bearings can also cause a shimmy or vibration when braking. This is because the wheel bearings are responsible for keeping the wheels aligned and rotating smoothly. If the wheel bearings are worn or damaged, they can cause the wheels to wobble or vibrate, which can be felt when braking.
4. Damaged steering components: Damaged steering components, such as the tie rods or control arms, can also cause a shimmy or vibration when braking. This is because these components are responsible for controlling the alignment and movement of the wheels. If they are damaged or worn, they can cause the wheels to vibrate or wobble, which can be felt when braking.
5. Tire imbalance: An unbalanced tire can cause the vehicle to shake when braking. This happens because the weight of the tire is not evenly distributed around the rim. When you apply the brakes, the uneven weight can cause the tire to wobble or vibrate.
6. Suspension issues: Worn out or damaged suspension components, such as the struts or shocks, can also cause the vehicle to shimmy when braking. This is because the suspension is responsible for keeping the vehicle stable and planted on the road. When it’s in poor condition, it can allow the wheels to move around excessively when you apply the brakes, which can cause the car to shake.
If you are experiencing a shimmy or vibration when braking, it is important to have the cause diagnosed and repaired as soon as possible. This will help to ensure the safety of you and your passengers, as well as preventing further damage to your vehicle.
