Can You Continue Driving with Overheated Brake Discs?
2 Answers
You should not continue driving with overheated brake discs. Here are the relevant explanations: Friction: The working principle of brakes mainly comes from friction, which converts the kinetic energy of the moving vehicle into frictional heat energy by utilizing the friction between the brake pads and the brake disc (drum), as well as between the tires and the ground, to bring the vehicle to a stop. Therefore, if you notice any abnormal conditions with the brake pads, they must be addressed immediately. Thickness: Under normal driving conditions, the brake pads should be inspected every 5,000 kilometers. Not only should the remaining thickness be checked, but also the wear condition of the pads, whether the wear on both sides is even, and whether the retraction is smooth, etc. Any abnormal conditions must be dealt with immediately.
A couple of days ago, I drove down a long slope and the brake discs got extremely hot, which really panicked me. I immediately found a safe spot to pull over and let them cool down. Later, I learned my lesson—realizing the high risk of overheating. Continuing to drive could lead to brake failure, and if a rear-end collision or accident happened, it would be a big problem. I also checked the brake fluid level and wear condition. Now, I’ve developed the habit of using manual downshifting more often to slow down, reducing brake usage. Such issues can’t be delayed—they must be addressed promptly, as safety comes first. It’s best to let the brakes cool for at least half an hour to avoid potential hazards, and regular maintenance should include frequent checks of the braking system. Remember, life is the most precious thing—if you notice overheating, don’t push your luck.
