What Causes Vehicle Body Shaking During High-Speed Braking?
2 Answers
Vehicle body shaking during high-speed braking is caused by: 1. Incorrect tire dynamic balance; 2. Malfunction in the vehicle's transmission system; 3. Worn or loose half-shaft tie rod ball joints or detached rubber bushings at the joints; 4. Twisted or deformed drive shaft or loose, dry, and rusted universal joints; 5. Uneven brake discs; 6. Overly loose or tight power steering belt. Solutions for vehicle body shaking during high-speed braking include: 1. Promptly inspecting or replacing tires; 2. Checking the vehicle's transmission system for any malfunctions; 3. Inspecting whether the half-shaft tie rod ball joints are worn or loose or if rubber bushings at the joints are detached; 4. Checking the drive shaft for any twisting or deformation; 5. Replacing the brake discs; 6. Adjusting the power steering belt.
When braking at high speeds, the car body shakes. I've encountered this several times on the highway, feeling the steering wheel tremble. It's mostly due to brake disc issues. Driving at high speeds and braking hard causes the disc and pads to generate heat too quickly, leading to uneven disc surfaces that cause vibrations when braking. Sometimes uneven brake pad wear or calipers not retracting properly can also cause this. It's best to get it checked at a repair shop immediately—resurfacing or replacing the discs and pads should fix it. Don't delay. Drive smoothly and avoid sudden braking whenever possible. Regular wheel balancing and maintenance can also help prevent such issues. If the shaking is severe and braking distance increases, the risk is significant—safety comes first.
