DOT 3 and DOT 4 are the most commonly used brake fluids. DOT 3 is compatible with DOT 4 brake fluid however DOT 4 offers a higher boiling point. 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. 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.
