* Weight transfer. When you brake, the weight of your car shifts forward. This can cause the front wheels to lose traction and the car to start to shake.
* Tire wear. If your tires are worn, they may not be able to grip the road properly and can cause the car to shake when you brake.
* Warped rotors. If the rotors on your brakes are warped, they can cause the car to shake when you brake.
* Loose suspension components. If any of the suspension components are loose, they can cause the car to shake when you brake.
* Wheel bearing problems. If the wheel bearings are worn or damaged, they can cause the car to shake when you brake.
If you experience shaking when you brake at high speeds, it's important to have your car checked by a qualified mechanic to identify the cause and get it repaired.
