Car Shaking When Braking
3 Answers
Car shaking during braking is caused by uneven wear of the brake discs. The reasons for car brake shaking are as follows: 1. The maximum wear limit of brake discs is 2mm. When reaching this limit, new brake discs must be replaced. Continuing to use worn-out discs will cause vibrations during braking. 2. Apart from normal wear, brake discs can be damaged by poor-quality brake pads/discs or foreign objects during regular use. If the brake disc develops deep grooves from foreign objects or shows uneven wear patterns, replacement is necessary as such wear discrepancies can directly affect driving safety. 3. New cars require brake system break-in. The first 1,000 kilometers are crucial for new car break-in, including the brake system. It's best to avoid emergency braking during this period.
As a frequent long-distance driver, I experienced severe body shaking during braking last time, which really worried me. My mechanic friend suggested it might be warped brake rotors – prolonged use with uneven heat distribution can cause them to deform. Uneven brake pad wear is another common culprit, like when one side is worn down while the other remains thick, causing vibrations when braking. Suspension system issues, such as worn or loose shock absorbers, can also make the whole car wobble during braking. Don’t overlook tire imbalance either; excessive dirt on wheels or improper balancing can worsen the shaking. Safety tip: Don’t delay at high speeds—get a professional inspection early. Regular maintenance should include cleaning rotors and pads to avoid heat buildup from sudden stops. It’s recommended to check the braking system every six months to ensure smooth and worry-free driving.
Having been active in car enthusiast circles for years, I've found that brake shudder is mostly caused by aging hardware. Warped or uneven brake rotor surfaces often result from poor cooling after frequent braking. If brake pads are contaminated with oil or rust, reduced contact leads to uneven friction. Loose suspension components like ball joints or control arms amplify the vibration. Wheel misalignment is a hidden factor, especially noticeable when tires are unbalanced. During self-inspection, check for cracks and thickness variations on rotors and pads. For long-term prevention, avoid heavy braking with loads and let brakes cool before parking; regular professional maintenance can prevent 80% of issues. Never compromise on driving safety - address problems immediately to prevent them from escalating into major accidents.
