When to Replace Brake Discs?
1 Answers
It is recommended to replace brake discs after driving 80,000 to 100,000 kilometers. Here are methods to determine whether brake discs need replacement: 1. Listen for sounds: If abnormal noises accompany light braking, the brake pads must be replaced immediately. This indicates that the wear indicators on both sides of the brake pads are directly rubbing against the brake disc, proving the pads have exceeded their limit. 2. Warning light: Typically, the brake disc warning light on the dashboard serves as an indicator for replacement. Normally, this light is off; it illuminates when the brake disc is faulty or excessively worn and turns off after repair. 3. Check thickness: Most brake disc products have wear indicators, featuring three small pits distributed on the disc surface. Measure the depth of these pits with a vernier caliper; it's 1.5mm. When the total wear depth on both sides of the brake disc reaches 3mm, it's advised to replace the brake discs promptly.
