Why Is There Noise When Braking a New Car?

[VonPaisley]

New car brake pads and discs are brand new, which can cause noise during braking. The noise can be divided into vibration friction and sharp hissing sounds, which will disappear after a few hundred kilometers. Below is an introduction to new car usage: 1. First, the various systems of the new car need to undergo a break-in period. Many components in a new car have not yet reached their optimal state of cooperation, such as the contact points between two gears, where there might be some imperfections at the edges. During the break-in period, these edges will be smoothed out. 2. During the car's break-in period, it's best not to drive too fast, with a maximum speed of 100 km/h recommended. Additionally, it's advisable to drive on various road conditions during the break-in period, such as highways, to allow the new car's components to adapt to different road conditions and achieve optimal performance. 3. Drivers should pay attention to whether there are any faults in the new car while driving, such as water leaks. Although the probability of faults in a new car is low, for safety reasons, it's necessary to check carefully. Once a fault is discovered, it should be repaired promptly. Continuing to drive with a fault may damage the engine.
