Maintain the braking system in your 2017-2019 Chevy/GMC 6.6L L5P Duramax by replacing the brake fluid on a regular basis. Brakes are one of the most important components of vehicle safety although brake fluid is typically one of the most neglected fluids. 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. Many manufacturers recommend replacing the brake fluid every 2-3 years or at specific mileage intervals. It is very important to follow the manufacturer's recommended service schedule as well as testing your brake fluid occasionally. 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. Shop XDP for all the leading producers of brake fluid including Lucas Oil, and more!
