Girling Brake Fluid is also known as DOT 4 brake fluid, and is a polyalkylene glycol ether based hydraulic fluid. It is used in the braking systems of automobiles and motorcycles in order to transfer pressure from the driver's foot to the brake calipers. When exposed to Girling Brake Fluid, rubber can become brittle and prone to cracking and tearing due to its high boiling point, as well as its ability to strip away the rubber's natural oils. Additionally, prolonged exposure to Girling Brake Fluid can cause rubber to become swollen, leading to a decrease in its dimensional stability.
