One hidden benefit of this process is that every bleeder screw on the system must be opened to complete it therefore reducing the risk of them seizing with age leading to the replacement of a caliper or two down the road. This accelerates corrosion leading to fluid leaks. With age, water is introduced into brake lines and hoses via condensation on the steel portions of the lines and the cast metal parts of the wheel brake units. The main concern that brake fluid replacement addresses is the reduction of the water content in the fluid. This fluid seldom has a recommended replacement interval with carmakers.
