How Many Kilometers Should Brake Discs and Brake Pads Generally Be Replaced?

[MaggieFitz]

Under normal circumstances, brake pads should be replaced every 30,000 to 40,000 kilometers, and brake discs every 60,000 to 70,000 kilometers. The specific situation depends on the actual wear condition. Below is relevant information: 1. Conditions requiring replacement: If there is a sharp metal-on-metal friction sound when lightly braking, first check to rule out noise caused by normal wear-in of the brake pads. If the brake pads are severely worn, replace them immediately. If the noise is caused by damage or scratches on the brake disc, replace the brake disc promptly. 2. Factors affecting wear: The material and structure of low-quality brake discs can easily cause premature wear of the brake pads. Long-term speeding, frequent braking, overloading, and prolonged use under high temperatures are also reasons for severe wear of brake pads and discs. In addition, long-term damage to the brake caliper in the braking system, causing the brake to not release properly, can also lead to prolonged grinding between the pads and discs, resulting in severe wear.
