Why is flushing brake fluid so important?
Brake fluid, like other fluids used in the automobile, needs to be changed at regular service intervals. Because brake fluid deteriorates over time, we recommend it be changed every two years or 24,000 miles. If the vehicle is operating in humid climates, it may be necessary to change the fluid more often. The most commonly used brake fluids, DOT 3 and DOT 4, are glycol-based fluids that have the characteristic of being hygroscopic. This means that brake fluid can absorb and retain moisture. As moisture enters the brake system, it can then be dispersed throughout the entire system. This prevents water from forming within the system and freezing or boiling before the fluid itself. Moisture also reduces the brake fluid’s lubricating capabilities and will dilute its anti-corrosion additives. This allows rust, corrosion and sediment to form within the hydraulic brake system. Additionally, the sediment migrates to the lowest points in the system during normal brake operation. This results i
