Your bike’s hydraulic fluid is another one of the unsung heroes of motorcycling. Imagine how you’d feel if you came bombing down into a tight right-hand turn with oncoming traffic and had your brake lever pull back to the grip. Yeah, that’d probably ruin your day. The reason this could happen is that most hydraulic fluids are hygroscopic, which means they have a taste for water and will gradually suck moisture past the rubber seals in your calipers. If your fluid is contaminated with water, heavy brake use will raise the temperature to the point where the water will boil (at a significantly lower level than pure fluid would), leading to brake fade and the dread-inducing, lever-to-the-grip braking experience.

So, again we have to ask: When did you last change your hydraulic fluid? That’s okay, as it’s an easy thing to remedy.
