PRF 608 Racing Brake Fluid by AP Racing - GTR

The key components of stopping your vehicle are the brake pads, calipers, brake lines, master cylinder, brake pedal and brake fluid. You would consider regular inspection and maintenance mandatory on all of these safety related parts, yet changing your brake fluid has become the missing piece of the puzzle. We have had "you must change your engine oil regularly" hammered into our heads to prolong the life of the engine and protect it from dirt and particles from damaging engine components. You also need to pay attention to servicing your brake fluid on a regular basis (most manufactures recommend every two years). Brake fluid's job is to carry pressure from the master cylinder, through the brake lines to the calipers, which puts pressure on the back of the brake pads that then clamp against the rotor to stop the vehicle. New brake fluid starts as an incompressible liquid and allows the brake system to function at peak design efficiency. The problem is over time it will become contaminated and become more compressible. The better brake fluids typically are a glycol/ether chemical based fluid that has different hygroscopic rates (absorption of water from air) and boiling levels. As the brake fluid absorbs moisture over time, the incompressibility will deteriorate and the brake pedal travel will increase as pressure in the system is reduced, plus the boiling point of the brake fluid is also reduced. When overheated, brake fluid can boil which creates gas bubbles and the incompressibility can deteriorate to the point of having to pump the brakes to regain pressure (track enthusiasts can relate to this). Water saturated brake fluid will cause corrosion and increase viscosity (can harm ABS/ESP systems). The rule of thumb, the higher the boiling point, the greater the hygroscopic properties and the higher frequency of maintenance. Most track cars using high temperature "race" brake fluids should change brake fluid or at least bleed the calipers after every race.
