Guide to the Top Brake Fluid by Boiling Points

When choosing a brake fluid, you have to consider its boiling points. There are two, wet and dry. What is the difference? Dry is brand new, fresh, not contaminated fluid. Wet boiling point will be with 3.7% water by volume. Keep in mind that as soon as brake fluid touches oxygen, it will begun to absorb moisture. Sure, fluid with a high dry boiling is nice, but wet boiling point is just as important. If you boil your fluid, you will not stop. Here are the top 10 fluids in both boiling points:
