Maintain proper performance of the braking system in your 2015-2019 Ford Transit 3.2L Powerstroke with new brake fluid. Despite being a closed system, brake fluid will eventually begin to collect moisture. As a result, the braking performance will begin to suffer due to the decreased boiling point caused by the water. There are many brake fluids available such as DOT 3, DOT 4, DOT 5, and DOT 5.1. The most widely utilized braking fluids are DOT 3 and DOT 4. While DOT 3 and DOT 4 brake fluids are interchangeable, DOT 4 has a higher boiling point. Although brake fluid is sometimes one of the most overlooked fluids, brakes are one of the most crucial safety features of a vehicle. Manufacturers typically advise changing the brake fluid every two to three years or at predetermined mileage intervals. It's crucial to adhere to the manufacturer's suggested maintenance schedule.
