When a steering wheel shakes while braking, it can be a sign of an issue with the vehicles tires or brakes. Here are some common causes of a shaky steering wheel when braking:
-
Warped Rotors: Brake rotors are the smooth, flat metal discs between the brake pads on each car wheel. When you use the brake pedal, the brake pads push against a brake rotor to bring the car to a stop. If the rotors become warped, they can cause the steering wheel to shake when you brake.
-
Worn Brake Pads: Over time, brake pads can become worn down and need to be replaced. If the pads become too thin, they can cause the steering wheel to shake when you brake.
-
Sticking Brake Caliper: Brake calipers hold the brake pads and lower them each time you slow down. If a brake caliper gets stuck, it can cause the steering wheel to shake when you brake.
-
Tire Alignment Issues: Your vehicle's suspension system is designed to align your tires, helping them evenly meet the road's pavement. Over time, road turbulence, rough driving, and other hazards can throw off this alignment, causing one or more of your wheels to rest at a skewed angle. Even slight alignment issues can cause steering wheel shaking or vibrations.
-
Debris Buildup: Sticking brake calipers are commonly caused by worn hoses, debris buildup, and DIY brake installation, among other potential sources.
If you notice your steering wheel shaking when you brake, it's important to get it checked out by a mechanic as soon as possible. Ignoring the issue can allow it to grow into a larger problem for your car.
