What Causes the Abnormal Noise When a New Car Goes Over Speed Bumps?

[VanElliot]

New cars may produce abnormal noises when going over speed bumps due to gaps in the brake pads or brake discs. Causes of Abnormal Noise: When driving over bumps or speed bumps, if the noise disappears when lightly applying the brakes, it indicates gaps in the brake pads or brake discs. These gaps can cause metallic squeaking sounds upon external impact. While this does not affect braking performance, it can be annoying. The solution is to visit a nearby repair shop and have a mechanic adjust the gaps. Reduce Speed in Advance: When approaching speed bumps, it's best to slow down early and pass over them straight on, distributing the impact evenly across both tires. This balances the load on the left and right suspension systems. Avoid slamming on the brakes or accelerating, allowing the vehicle to pass over the speed bumps naturally. This method is safer, protects the suspension and steering systems, and minimizes damage to the car.
