Why should the Brake system be Flushed?
Brake fluid is hygroscopic meaning it can absorb moisture from the air resulting in a dangerous reduction
of its boiling point. Water contaminated brake fluid under repeated working pressure boils and creates air
bubbles. Under severe conditions, this can result in complete brake system failure.
Water contaminated brake fluid causes electrolysis to occur inside the brake system. The oxygen contained
in the water droplets cause oxidation. Electrolysis and oxidation corrodes the hydraulic master cylinder and
wheel cylinders, and steel brake lines from the inside. Pressure bleeding has been proven the most effective
method in flushing and bleeding hydraulic brake systems. Flushing the brake system and replacing the dirty
and contaminated brake fluid with fresh brake fluid can often avoid expensive repairs.
