What Causes Steering Wheel Shaking When Braking at High Speeds?

[CamilleDella]

The reasons for steering wheel shaking when braking at high speeds are as follows: 1. Uneven brake disc wear: When the brake discs wear unevenly, steering wheel shaking may occur during high-speed braking. When the car reaches a certain speed and brakes, the left and right wheels on the same axle may experience asynchronous braking forces within a single rotation, leading to an imbalance in braking torque. This imbalance causes a pulsating effect—alternating between tight and loose braking. If this imbalance reaches a certain level, it can result in unequal rolling speeds between the left and right wheels, leading to lateral wheel oscillation, which is then transmitted to the steering wheel. 2. Drivetrain malfunction: Another possible cause of steering wheel shaking during high-speed braking could be an issue with the vehicle's drivetrain. In such cases, it is advisable to inspect components like the tie rods and tie rod ends for signs of rust or looseness.
