1. Warped Brake Rotors:
- Warped brake rotors are a primary cause of brake shaking. Rotors can warp due to excessive heat buildup, uneven pad wear, or manufacturing defects. When the warped rotor comes in contact with the brake pads, it causes the brake pedal to pulsate and the steering wheel to shake.
2. Uneven Brake Pad Wear:
- Uneven wear on the brake pads can lead to brake shaking. When the pads are worn unevenly, they may not apply pressure evenly on the rotors, causing the vehicle to shake. This is often a result of worn-out brake pads, uneven caliper piston movement, or a seized brake caliper.
3. Caliper Issues:
- A faulty or misaligned brake caliper can cause the brake pads to drag or release unevenly, leading to shaking. A sticking caliper piston or a malfunctioning caliper slide pin can cause the brake pads to stay engaged with the rotor even after the brake pedal is released, resulting in vibrations.
4. Worn Ball Joints or Tie Rods:
- Worn ball joints or tie rods can also contribute to brake shaking. These components connect the steering system to the wheels and play a role in maintaining the proper alignment of the wheels. If they become worn or loose, they can affect the vehicle's stability and cause shaking when braking.
5. Wheel Alignment Issues:
- Incorrect wheel alignment can cause the tires to wear unevenly, leading to brake shaking. Proper wheel alignment ensures that the tires make even contact with the road, reducing the chances of shaking during braking.
6. Faulty Brake Hoses:
- Deteriorated or flexible brake hoses can cause brake fluid pressure fluctuations and affect braking efficiency. This can result in brake shaking, especially when the brakes are applied at higher speeds.
7. Axle Problems:
- Faulty CV (constant velocity) joints or a damaged axle can also cause the vehicle to shake during braking. Worn or damaged CV joints can produce a clicking sound and cause the steering wheel to shake, especially when turning and braking simultaneously.
If you experience shaking or vibrations when you brake, it's essential to have your vehicle inspected by a qualified mechanic to identify and address the underlying issue. Driving with shaking brakes can compromise your safety and the safety of others on the road.
