Flush the contaminated fluid in your 2004.5-2007 Dodge 5.9L Diesel and top it off with new brake fluid. Brake fluid will eventually start to accumulate moisture despite being a closed system. As a result of the water's lowered boiling point, the braking efficiency will start to deteriorate. 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. Brake fluid is one of the most frequently ignored fluids when it comes to basic maintenance, despite the fact that brakes are one of the most important safety aspects of a vehicle. Manufacturers often advise changing the brake fluid every two to three years or after a certain number of miles. Following the manufacturer's suggested maintenance schedule is crucial, as is occasionally checking your brake fluid.
