What Causes Car Vibration When Braking?
3 Answers
Vehicle vibration when braking can be caused by the following reasons: 1. Uneven brake disc surface or excessive radial runout. 2. Significant deviation in wheel alignment data. 3. Tire pressure being too high or too low. 4. Abnormal tire wear. 5. Wheel rim deformation. Additional information on brake maintenance methods is as follows: 1. High-temperature protection to prevent brake system corrosion, avoid brake pad seizure due to high temperatures, and eliminate brake squeal. 2. Regularly replace brake fluid. 3. Clean oil stains, dirt, and friction dust from brake discs, drums, and any components to ensure good brake disc heat dissipation. 4. Regularly check the thickness of brake pads or shoes.
I've been driving for almost thirty years and have encountered the issue of car trembling when braking several times, usually caused by warped brake rotors. Due to prolonged use, especially with frequent hard braking, the rotors can overheat and warp, leading to steering wheel vibration and unstable vehicle movement when you hit the brakes. Additionally, uneven wear of brake pads or problems with the suspension system, such as aging shock absorbers, can also trigger similar issues. I remember once driving in the rain when the car suddenly shook violently upon braking. Upon inspection, it turned out to be a combination of warped brake rotors and incorrect tire pressure. Replacing the rotors and adjusting the tire pressure immediately resolved the problem. I recommend paying attention to maintenance, avoiding sudden braking in congested areas, and regularly visiting professional shops to inspect the braking system to ensure driving safety.
After years of car repair experience, brake system issues are quite common. When the car vibrates upon braking, the main causes are often uneven or warped brake rotors, surface rust, or improper heat treatment leading to vibrations. Uneven brake pad wear or sticking brake calipers can also cause shaking. Suspension components like control arm bushings or tire imbalance should also be checked. It's recommended to inspect brake rotor thickness—replacement is usually needed if below standard values. Use instruments to test brake fluid and system pressure. Car owners shouldn't ignore minor vibrations; regular maintenance can prevent major failures.
