What needs to be replaced when the brakes don't work well?

When the brakes don't work well, the brake pads or brake discs need to be replaced. Here is some relevant information about brakes: 1. Definition: The braking system generates friction between the brake pads and the drum or disc, converting the kinetic energy of the moving vehicle into heat energy during the friction process. Common types of braking systems are "drum brakes" and "disc brakes". 2. Technique: When braking, release the brake before the vehicle comes to a complete stop. Continuously pressing the brake can cause a strong impact when the vehicle stops. The technique is to release the brake once before the vehicle fully stops, then gently apply the brake again until the vehicle comes to a complete halt.

Once when I was driving, I noticed the brakes felt spongy and responded slowly, which felt extremely dangerous. After inspection, the mechanic said the brake pads were severely worn and replaced them with new ones, and the problem was instantly resolved. If you drive frequently, brake pads may wear thin every 20,000 kilometers. Additionally, the brake fluid might be contaminated or have air bubbles, leading to insufficient hydraulic pressure, so it's essential to replace the fluid regularly to ensure the braking system works smoothly. If the brake discs are warped or scratched, replacing them can make braking more stable. In short, don’t delay—visit a repair shop promptly to inspect and replace necessary components, as safety comes first. Remember, in winter, the cold weather makes fluids thicker, affecting performance even more, so preventive maintenance can help avoid issues.

I usually enjoy modifying cars and have done many tests when the brakes don't work well. Replacing them with high-performance brake pads significantly improves the friction coefficient and braking effect. It's also important to check if the brake fluid is aged or contains too much water, in which case it must be replaced. If the ABS light comes on, it might be necessary to replace the sensor or repair any leaks in the brake lines. If the brake discs are unevenly worn, replacing them with high-quality discs can make a big difference. Regularly inspecting the brake system ensures every component functions properly. After years of car modification, I've learned that details matter greatly—never overlook minor issues, as they can pose high risks at high speeds. Regular maintenance is key to saving money and ensuring safety.

I just started learning to drive and I'm very nervous about the brakes not working well. I consulted an experienced driver. He said the first thing to check is the wear level of the brake pads; if they're thin, they need to be replaced. Insufficient or deteriorated brake fluid can be resolved by replacing it with new fluid. In daily driving, pay attention to any screeching sounds, as they are often a sign that the pads are about to fail. If you don't understand mechanics, just go to a repair shop and let them do a comprehensive check; don't try to fix it yourself. Small issues can turn into major problems, making repairs more expensive and potentially causing accidents. Remember, maintaining a healthy braking system is a basic safety measure, and new drivers must be extra cautious on the road.
