1：Excessive Use and Over-Speed Braking: During the daily use of electric cars, if we carry too much weight or drive too fast, braking can become overloaded. This can result in a sharp, piercing noise during braking, which can be uncomfortable.
2：Brake Device Quality Issues: Electric cars use different types of brake devices such as regenerative brakes and expansion brakes. Particularly with regenerative brakes, resistance inconsistencies can increase friction, leading to sharp noises. Choosing substandard brake devices can also contribute to this issue.
3：Brake Pad Problems: Brake pads in electric cars are consumables that wear out over time. Improper installation or significant wear of brake pads can cause screeching noises and other issues during braking, affecting driving comfort.
Recommended Solutions:
1：Replace Brake Pads: Timely replacement of brake pads is crucial. Avoiding overweight and over-speed driving and selecting appropriate brake pads can effectively reduce sharp noise.
2：Choose High-Quality Brake Devices: Pay attention to selecting reliable brake devices and avoid using poor-performing brakes. Expansion brakes are a good choice as they offer good braking performance with low noise, enhancing driving comfort.
3：Regular Inspection and Cleaning: Regular inspection and cleaning of brake devices are essential. Removing accumulated dust and debris, as well as replenishing brake fluid in a timely manner, can significantly reduce sharp noises.
