Brake fluid is hygroscopic, meaning it absorbs moisture out of the air, and that is what lowers its boiling point over time and corrodes the system from the inside. That is the real argument for flushing on a schedule rather than only topping off. Use fluid from a sealed container and close it immediately after pouring.

Fluid Specifications:

• DOT 3 specification brake fluid.
• For hydraulic disc and drum brake systems.
• For select Chrysler, Dodge, Jeep and Ram applications.
• 12 oz. container.
• Do not reuse opened fluid. Avoid contact with painted surfaces.
