Why does the car shake when braking?
2 Answers
The reason for the car shaking when braking is: uneven wear of the brake discs. This phenomenon mainly occurs when the driver frequently uses intermittent braking (pumping the brakes), causing the brake discs to become uneven with high and low spots. When braking, the brake pads gripping these uneven surfaces will cause shaking. Therefore, drivers should use the brakes properly and avoid such issues in the future. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force.
I've been driving for many years and have encountered the issue of car shaking when braking quite often, which is usually related to brake discs. Due to frequent use, brake discs can cool unevenly under high temperatures, leading to deformation or surface irregularities. Wheel imbalance is another common cause, such as not performing dynamic balancing after tire replacement, which can cause vibration while driving. Loose suspension components like tie rods can also transmit vibrations to the brakes. The ABS system is designed to produce normal shaking during emergency braking, but abnormal shaking should be taken seriously. I recommend checking the brake discs and calipers as soon as possible. If the shaking feels severe, pull over immediately to avoid accidents on the highway. Regular maintenance of the braking system is crucial, including checking brake pad wear and disc thickness. Don't wait for minor issues to become major problems, as this not only increases repair costs but also compromises safety.
