To comprehend the importance of a brake fluid flush, it’s essential to understand the role of brake fluid in a vehicle’s braking system. Brake fluid serves several crucial purposes, including maintaining hydraulic pressure, preventing corrosion, and ensuring optimal braking performance.
Hygroscopic Nature of Brake Fluid
Brake fluid is hygroscopic, meaning it has the ability to absorb moisture from the surrounding air. Over time, moisture can find its way into the brake system through microscopic openings in the reservoir or brake lines. This moisture accumulation can have detrimental effects on the brake fluid and the overall braking system.
Moisture in the brake fluid can lead to a decrease in its effectiveness, as water content lowers the boiling point of the fluid. During heavy braking, the brake fluid can reach high temperatures. If the boiling point is too low due to moisture contamination, it can result in brake fade or even brake failure. Therefore, it is crucial to regularly flush the brake fluid to maintain its integrity and performance (Natrad).
Corrosion and Damage to Brake Components
Moisture present in the brake fluid can also cause corrosion and damage to various brake components. Over time, the moisture reacts with metal components, such as calipers, wheel cylinders, and master cylinders, leading to rust and deterioration. This corrosion can compromise the structural integrity of these components and diminish their functionality (Natrad).
Contaminated brake fluid can also result in the formation of sludge and debris within the brake system. This can clog brake lines, valves, and other crucial parts, hindering the smooth operation of the braking system. As a consequence, braking performance may be compromised, and the risk of accidents can increase (Natrad).
Recommended Brake Fluid Flush Interval
To maintain optimal braking performance and safety, it is recommended to perform a brake fluid flush every 2 years or 40,000 kilometers, whichever comes first (Natrad). This interval ensures that the brake fluid is fresh, free from moisture, and capable of withstanding the demands of braking under various conditions.
Neglecting to change the brake fluid can lead to a variety of issues, including reduced braking efficiency, spongy brake pedal feel, longer stopping distances, and potential brake system failure (RepairSmith). Regular brake fluid flushes are crucial preventive maintenance measures that can help prevent costly repairs and replacements of brake system components, ensuring consistent and reliable braking performance (Natrad). By adhering to the recommended brake fluid flush interval, car owners can maintain the safety and efficiency of their vehicle’s braking system for years to come.
