Juice Lubes Dot 5.1 Brake Fluid is a high performance brake fluid for all Dot Oil brake systems. It has a boiling point of 260c which is pretty warm. So if you ever manage to cook this then congratulations on being the first person to descend Mt Everest on a bike. In any other situation it will provide consistent and high stopping power. Obviously other factors such a pad wear and correctly bled brakes will have a big affect on performance so always check these as well.
