What Causes the Entire Car to Shake When Braking?
2 Answers
The reasons for the entire car shaking when braking are: 1. Tire deformation; 2. Incorrect tire dynamic balance; 3. Vehicle transmission system failure; 4. Worn or loose ball joints or detached rubber sleeves at connection points; 5. Twisted or deformed drive shaft; 6. Uneven brake discs; 7. Overly loose or tight power steering belt. Braking, also known as stopping, refers to the action of halting or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The methods to address the entire car shaking when braking are: 1. Check whether the ignition coil has leakage or internal short circuit; 2. Check whether the ignition coil wiring plug is loose or has poor contact; 3. Check whether there is corrosion at both ends of the battery; 4. Check whether the vehicle body grounding is good.
I've been driving my car for over a decade and have encountered brake shudder several times. Usually, this is caused by warped brake rotors or uneven surfaces. When you press the brakes, the brake pads rub against the uneven rotors, making the car shake like an earthquake. Another common reason is uneven wear of brake pads or improper installation, which creates unstable contact points. If there's an issue with the suspension system, such as worn-out shock absorbers or insufficient bounce, it can also cause the entire car to shake. I've also considered out-of-round wheels or uneven tire wear as potential causes. The last time my car shook badly, driving felt like being on a boat, so I immediately went to a nearby repair shop. The technician quickly identified severe scoring on the brake rotors, and replacing them fixed the issue. Safety first—I recommend not pushing through it but stopping immediately and seeking professional inspection. Regular maintenance of the braking system can help avoid such problems. Never ignore these minor issues, as they can easily lead to major accidents.
