Flush the contaminated fluid in your 2016-2022 Chevy 2.8L Duramax and top it off with new brake fluid. Although brake fluid is sometimes one of the most overlooked fluids, brakes are one of the most crucial safety features of a vehicle. 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. 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.
