Flush the contaminated fluid in your 1999-2003 Ford 7.3L Powerstroke and top it off with new brake fluid. Manufacturers often advise changing the brake fluid every two to three years or after a certain number of miles. Following the manufacturer's suggested maintenance schedule is crucial, as is occasionally checking your 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. 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. 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.
