* Brake rotors warped. This is the most common cause of steering wheel shake when braking. When brake rotors are warped, they can cause the brake pads to vibrate against them, which in turn causes the steering wheel to shake. Warped rotors can be caused by a number of things, including overheating, uneven wear, and damage from road debris.
* Brake calipers sticking. If the brake calipers are sticking, they can cause the brake pads to drag against the rotors, which can also cause the steering wheel to shake. Sticking calipers can be caused by a number of things, including rust, dirt, and debris.
* Wheel bearing problems. If the wheel bearings are worn or damaged, they can also cause the steering wheel to shake when braking. Worn wheel bearings can allow the wheels to wobble, which can cause the steering wheel to vibrate.
* Driveline problems. If there is a problem with the driveline, such as a worn universal joint or a bent driveshaft, it can also cause the steering wheel to shake when braking. Driveline problems can be caused by a number of things, including wear, tear, and damage from road debris.
If you are experiencing steering wheel shake when braking, it is important to have your vehicle inspected by a qualified mechanic to determine the cause of the problem. Ignoring this problem can lead to serious safety issues, such as loss of control of the vehicle.
