What Causes Steering Wheel Shaking When Braking in a Car?

[Pedro]

Steering wheel shaking when braking in a car indicates a fault in the braking system. The friction between the brake pads and brake discs causes the steering knuckle to vibrate, which in turn affects the tires, leading to the steering wheel connected to the steering gear also shaking. Reasons for steering wheel shaking include: 1. Shaking at idle: Loose steering wheel bolts or rubber bushings; 2. Shaking during driving: Imbalanced wheel alignment; 3. Shaking when turning the steering wheel: Power steering belt too loose or too tight; 4. Shaking when braking at high speed: Excessive or frequent braking, overheating of brake pads and discs, causing deformation when cooling; 5. Shaking on bumpy roads: Worn or loose tie rod ends or detached rubber bushings at joints. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, and aircraft, converting the force applied by the driver on the steering wheel's edge into torque, which is then transmitted to the steering shaft.
