What Causes Vehicle Body Shaking When Braking?
4 Answers
Shaking when braking is caused by: uneven wear of the brake discs. The solution is to replace the brake discs or resurface them. Methods for maintaining brake discs include: 1. Develop good driving habits; 2. Avoid emergency braking; 3. Regularly inspect brake pads and discs; 4. Check the thickness of the friction material; 5. Have a professional inspect the brake shoes; 6. Use original equipment manufacturer (OEM) brake pads and discs when replacing. The function of brakes is to reduce speed or bring the vehicle to a stop. The working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and drums, as well as between the tires and the road surface, thereby slowing down or stopping the car.
I encountered a similar situation when repairing my car before. The main reason for the car body shaking when braking is likely due to uneven brake disc surfaces, which can become deformed from prolonged use or frequent braking at high temperatures, causing rhythmic pulsations. Additionally, uneven wear of the brake pads or contamination with grease can also lead to inconsistent braking performance and vibrations. Loose wheel hub bearings can also have an impact, potentially amplifying vibrations when turning or braking. If the shock absorbers in the suspension system have aged and lack sufficient support, the overall stability of the car body will decrease. I remember a friend's car had this issue once, and ignoring it led to longer braking distances, almost causing an accident. So, I recommend going to a professional repair shop as soon as possible to check the brake discs. Resurfacing or replacing them can usually solve the problem—don't skimp on safety to save money.
Lately, I've been experiencing noticeable body vibrations while driving, especially when braking—the steering wheel even trembles. Initially, I suspected tire issues, but an inspection revealed the brake discs might be warped. Frequent stop-and-go traffic in summer causes the discs to heat up, expand, and then deform upon cooling, leading to vibrations. Poorly installed or unevenly worn brake pads can also make the car jerk during braking. Sometimes, uneven road surfaces combined with aging suspension amplify the shaking. I’ve also heard loose wheel hub bolts could cause similar symptoms. Whatever the case, don’t ignore it—it’s not just about driving comfort but safety. Visit a trusted repair shop for a thorough check. Usually, replacing brake pads or a simple adjustment fixes it. Spending on safety is always worth it.
Brake pedal-induced body shaking is mostly caused by issues in the braking system, such as warped brake discs with uneven surfaces that cause severe vibrations during braking. Incorrectly installed or excessively worn brake pads can also easily lead to body sway. Loose wheel hub bearings or misaligned tires can similarly cause additional vibrations. This situation is directly related to driving safety—frequent shaking indicates declining braking performance. If not addressed promptly, braking distances may increase, posing higher risks especially at high speeds. It's advisable to have a professional inspect the brake discs as soon as possible; simple resurfacing or replacement may suffice. Avoid DIY repairs to prevent exacerbating the issue—safety comes first, don't cut corners.
