What are the hazards of not replacing brake pads?

[Archie]

Failing to replace brake pads for an extended period can easily lead to a decrease in braking force, causing air resistance within the brake management system, which affects braking performance. It may also corrode the brake lines, damaging the internal valves of the anti-lock braking hydraulic assembly, and even prevent the normal operation of the brake transmission response. You should promptly replace the brake pads under the following circumstances: When the vehicle has traveled 40,000 kilometers or the brake pads have been in continuous use for 2 years. Due to prolonged use, they may deteriorate, making timely replacement necessary. If the vehicle experiences inconsistent braking force during normal driving, the brake pads should be replaced immediately. Before replacing the brake pads, clean the braking system thoroughly with alcohol. If the vehicle exhibits braking deviation, conduct a comprehensive inspection of the braking system. If the wheel cylinder rubber cups appear significantly swollen, it may indicate poor-quality brake pads. In this case, replace them with higher-quality brake pads and also replace the rubber cups. After installing new brake pads, ensure proper break-in to allow the pads and rotors to seat correctly for optimal braking performance. In most cases, new brake pads require at least 500 kilometers of full break-in to reach their best working condition. During this period, adjust your speed appropriately, anticipate road conditions when driving on highways to avoid sudden braking, as this affects braking force. Pay extra attention to early braking and maintaining a safe following distance in rain or snow. In most cases, after replacing brake pads three times, you should also replace the brake discs. Of course, during regular vehicle maintenance, always check the wear depth of the brake discs when replacing brake pads. If the wear reaches 2mm, replace them immediately.
