Maintain proper performance of the braking system in your 1998.5-2002 Dodge 5.9L Diesel with new brake fluid. Despite the fact the brakes are one of the most crucial safety features of a vehicle, brake fluid is one of the most overlooked fluids when it comes to routine maintenance. 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. Brake fluid will start absorbing moisture from the air over time. Since water lowers the boiling point of brake fluid, this water contamination may cause your brakes to begin to lose efficacy. There are several different types of brake fluids available, including DOT 3, DOT 4, DOT 5, and DOT 5.1. The DOT 3 and DOT 4 brake fluids are the most commonly used. DOT 4 has a greater boiling point than DOT 3, despite the fact that the two brake fluids are compatible. Shop XDP for all the top brake fluid manufacturers such as Lucas Oil, and more!
