Should Brake Pads Be Replaced Immediately If They Make Noise?

When there is a sharp sound during braking, it is time to replace the brake pads. The main performance characteristics of brake pads are as follows: 1. High performance: High friction coefficient (Golden Kylin ceramic brake pads have a friction coefficient of 0.45, which is considered high), heat resistance, and outstanding performance during high-speed and high-temperature driving, providing good braking effectiveness and comfort under such conditions. 2. Safety: Low heat fade, excellent recovery performance, ensuring braking performance does not degrade on mountainous roads or under high-temperature and high-speed conditions, thereby maximizing vehicle safety. They are highly suitable for use in mountainous areas, highways, and various other road conditions. 3. Comfort: Smooth braking, no noise, no pollution, and balanced braking. 4. Reasonable service life: For general non-modified vehicles under normal driving conditions, the lifespan of front brake pads is 30,000–50,000 kilometers, while rear brake pads last 80,000–100,000 kilometers. Front brake discs have a lifespan of 60,000–100,000 kilometers. For vehicles frequently driven in mountainous areas, the lifespan of both brake pads and discs is significantly shorter.
I've been driving for over a decade, and that squealing sound is always a reminder to change the brake pads. That screeching noise is usually a sign of the wear indicator, showing the pads are nearing their limit. If not replaced in time, the noise may worsen, wearing down the brake discs and leading to more expensive repairs. Safety-wise, longer braking distances could cause accidents. I recommend getting them checked at a repair shop as soon as you hear the sound—the standard is to replace them when they're below 3mm thick. Most repair shops measure for free, so don't delay. You might get a few more days, but don’t ignore it long-term. Check the braking system during regular maintenance to extend its lifespan and save hassle. Safety is more important than anything—your car is your partner, so proper maintenance is key.
As someone who frequently works on cars, I must say that brake pad squealing is a clear warning sign. The noise usually comes from the metal indicators on the pads, which start squealing when worn down to a certain point, signaling that it's time for replacement. If not addressed promptly, it can damage the brake discs or lead to reduced braking performance. I've helped fix many cases where ignoring it led to major issues. Get a quick diagnosis at a repair shop, and replace them if they're too thin. Nowadays, materials are better, and replacing pads is both cheap and quick—done in about half an hour. Make it a habit to check your tires and brakes monthly to catch issues early. Driving safety comes first; don't let small problems turn into big disasters.
