It is very important to follow the manufacturer's recommended service schedule for replacing the brake fluid. Manufacturers often recommend replacing the brake fluid every 2 to 3 years or at specific mileage intervals. Although the brakes are an essential part of your driving experience, brake fluid is often one of the most neglected fluids in a vehicle. Brake fluid will start absorbing moisture from the air over time. Since water lowers the boiling point of brake fluid, this water contamination may cause your brakes to begin to lose efficacy.
