How Often Should the Brake Fluid in an Audi A4L Be Replaced?
1 Answers
Audi A4L brake fluid should be replaced every 40,000 kilometers, and the recommended brake fluid model is LB000750M3. Over time, brake fluid can deteriorate or develop sediment, primarily due to moisture contamination, which can lead to excessive water content in the brake fluid. When operating under high temperatures, the moisture in the brake fluid can vaporize, negatively affecting braking performance. Therefore, regular inspections and timely replacement of the brake fluid are necessary. When replacing the brake fluid in an Audi A4L, the old fluid is drained from the bleed screws at each of the four wheels until new fluid flows out without any air bubbles. There are specific requirements for bleeding the brake fluid, involving a certain sequence for the four wheels. Generally, the process starts with the wheel farthest from the ABS pump and proceeds from the farthest to the nearest. After bleeding the brake fluid, it is essential to pump the brake pedal several times to ensure the brake calipers are properly engaged. During the bleeding process, brake fluid may come into contact with hands or suspension components. In such cases, rinse the affected areas with clean water and dry them with compressed air. It is also advisable to clean the brake fluid reservoir during replacement, as sediment and impurities can accumulate inside.
