How many kilometers do car brake discs need to be replaced?
1 Answers
Generally, brake pads need to be replaced every 30,000 to 40,000 kilometers, while brake discs require replacement around 70,000 kilometers. However, the replacement frequency should be measured based on individual driving habits. The measurement criteria are: 1. Observe the replacement frequency of brake pads. If the brake pads are replaced very frequently, then the thickness of the brake discs should be checked more often, because the usage of brake pads and brake discs causes relative wear, so the brake discs should be inspected regularly. 2. Determine based on the wear condition. Apart from normal wear, brake discs can also experience wear due to the quality of the brake pads or discs, or foreign objects during normal use. If the brake drum has deep grooves caused by foreign objects, or if the disc surface shows uneven wear, replacement is recommended, as such wear discrepancies can directly affect driving safety. 3. Check the wear condition of the brake discs. Inspect whether there are grooves deeper than 1 millimeter on the brake discs, check if the thickness on both sides of the brake discs is consistent, and look for any unevenness or cracks on the brake discs. If any of the above issues are present, the brake discs should be replaced immediately.
