How many kilometers does the brake pads of Audi A6 need to be replaced?

[MacCooper]

The service life of the front brake pads is 30,000-50,000 kilometers, and the rear brake pads can last 120,000-150,000 kilometers. Methods for checking brake pads: 1. Check the thickness: The thickness of a new brake pad is generally about 1.5cm, and it will gradually wear thinner with use. When the thickness is visually observed to be only about 1/3 of the original (approximately 0.5cm), the owner should increase the frequency of self-inspection and be ready to replace them at any time. Due to the wheel design of some models, visual inspection is not possible, and the tires need to be removed to complete the check. It is recommended to regularly inspect the wear condition of the brake pads to see if they are still usable, and not to rely solely on the indicator light. 2. Listen for sounds: If there is abnormal noise when lightly braking, the brake pads must be replaced immediately. 3. Feel the pedal: If you feel that the brake pedal requires more effort, often needing to press it deeper to achieve the previous braking effect, or if you notice that the pedal position is significantly lower during emergency braking, it may indicate that the brake pads have basically lost their friction and must be replaced at this time.
