How to Solve the Illumination of the Car Brake System Warning Light?

If there is a lack, pay attention to whether there is any oil leakage. Check if the parking switch has returned to its position. It is best to use a fault detector for inspection, which can quickly and accurately locate the fault, and then gradually find the cause.
When I saw the car's brake warning light come on, I quickly found a safe place to pull over. It's too dangerous to keep driving. Common reasons include low brake fluid, possibly due to a leak from the reservoir's poor seal or rapid brake pad wear consuming the fluid. I opened the hood to check the brake fluid reservoir level—it should be between the min and max marks. If it's low, top it up with the correct fluid, but don't use other liquids. If the light stays on after checking, it might be a sensor issue or brake system failure. In this case, don't attempt DIY repairs; drive straight to the nearest repair shop or 4S store for a safety check. Remember to have the mechanic inspect the brake system during regular maintenance to avoid accidents on the road.
As someone who has driven for several years, I remind everyone never to ignore the brake warning light—take immediate action when you see it. A simple self-check method: after parking, check if the handbrake is fully released, then take a quick look at the brake fluid level—if it's too low, try topping it up. If that doesn’t help, check for any foreign objects stuck near the tires or abnormal wear on the brake discs. If you're a novice and can't handle it, don’t hesitate—call a repair shop right away to describe the situation, so a minor issue doesn’t turn into a major fault. I’ve also seen cases where the light comes on due to poor wiring connections or moisture after rain, so keeping the chassis dry during regular car washes can help prevent this.
