Maintain the braking system in your 2019-2023 Ram 6.7L Diesel by replacing the brake fluid on a regular basis. 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. Over time brake fluid will begin absorb moisture in the air. This water contamination can cause your brakes to start losing effectiveness since water decreases the brake fluid's 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. Brakes are one of the most important components of vehicle safety although brake fluid is typically one of the most neglected fluids. XDP offers brake fluid from all the leading manufacturers including Lucas Oil, and more!
