How many kilometers does it generally take to replace the brake discs of a sedan?

Brake discs generally need to be replaced when the vehicle has traveled 80,000 to 100,000 kilometers. Brake discs are wear-prone components in the car's braking system. As the vehicle's mileage increases, the brake discs will continuously wear down. When the brake discs are worn to a certain extent, they need to be replaced promptly. The criteria for determining whether brake discs need replacement include observing the brake disc warning light, checking the thickness of the brake discs, and listening to the sound during braking. Observing the brake disc warning light: Normally, the brake disc indicator light is off. When the brake disc malfunctions or is excessively worn, the warning light will illuminate and turn off after repairs. When the warning light is on, the brake disc has worn to its limit, braking effectiveness has decreased, and driving safety is significantly compromised. It is recommended to regularly check the wear condition of the brake discs. Checking the thickness of the brake discs: Most brake disc products have wear indicators, with three small dimples distributed on the disc surface. Using a vernier caliper to measure the depth of these dimples, if the depth is 1.5mm and the total wear depth on both sides of the brake disc reaches 3mm, it is advisable to replace the brake discs promptly. Listening to the sound during braking: If there is abnormal noise when lightly applying the brakes, the brake pads must be replaced immediately. This is because the limit indicators on both sides of the brake pads are directly rubbing against the brake disc, indicating that the brake pads have exceeded their limit.
