Flush the contaminated fluid in your 2008-2010 Ford 6.4L Powerstroke and top it off with new brake fluid. Several manufacturers advise replacing the brake fluid every two to three years or at specific mileage intervals. Both regularly testing your brake fluid and replacing it at the manufacturer's recommended maintenance schedule are crucial to maintaining your brake system's performance. Brake fluids are offered with varying specifications including DOT 3, DOT 4, DOT 5, and DOT 5.1. The most widely utilized braking fluids are DOT 3 and DOT 4. Even though the two brake fluids are compatible, DOT 4 has a higher boiling point than DOT 3. Although brake fluid is sometimes one of the most overlooked fluids, brakes are one of the most crucial safety features of a vehicle. Brake fluid can eventually start to absorb moisture from the air, even though it is a closed system. Your braking performance will suffer as a result of this water contamination, as the boiling point of the brake fluid lowers.
