Maintain proper performance of the braking system in your 2020-2022 Ram 1500 3.0L EcoDiesel with new brake fluid. Brake fluids are available in DOT 3, DOT 4, DOT 5, and DOT 5.1. DOT 3 and DOT 4 are the most commonly used brake fluids. DOT 3 is compatible with DOT 4 brake fluid however DOT 4 offers a higher boiling point. 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. 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. Brakes are one of the most important components of vehicle safety although brake fluid is typically one of the most neglected fluids.
