Maintain the braking system in your vehicle by replacing the brake fluid on a regular basis. 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. Although brake fluid is sometimes one of the most overlooked fluids, brakes are one of the most crucial safety features of a vehicle. 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. 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.
