Motul's RBF600 brake fluid is the go-to for anyone participating in track days or other racing events. With a dry boiling point of 600F, it will hold up to much more abuse and higher brake temperatures than many other fluids to prevent brake fade
Two types of fade can occur when the brakes are overheated. Pad fade, and fluid fade. Pad fade occurs when the pad exceeds is maximum operating temperature. At this point you will be pressing down on the brake, and the pedal will stay firm, but the car will now slow down as well. Fluid fade is when the fluid in the caliper boils. This can be a much worse situation and the pedal will go to the floor and you get no braking power.
Neither situation is good, but you could argue that boiling the fluid is worse. As brake fluid ages, it absorbs water (yes, despite being a "sealed" system, you still get water in your brakes over time), and the boiling point is decreased. When new, RBF600 does not boil until 600F which is the dry boiling point. The wet boiling point, defined when water content reaches 3.5%, is 399. This is why it is important to bleed the brakes frequently.
Motul brake fluid comes in 500ml bottles. Generally, 2 are needed to fully flush and bleed an automotive brake system. As brake fluid collects water, open containers can not be stored for long periods of time.
