Do you know what brake fluid is? How does it work? If you don't know the answers to these questions, don't worry - you're not alone. A lot of people don't know much about brake fluid, and that's understandable, since it's not a topic that comes up very often.

Brake fluid is a type of hydraulic fluid. It's used in brake systems to transfer force from the pedal to the brakes themselves. When you press the brake pedal, it activates a piston in the master cylinder, which forces brake fluid through the system and into the calipers.

Brake fluid is critical to the proper functioning of your brake system, so it's important to know a little bit about it. Here are some facts about brake fluid that you may not know:

-Brake fluid is made up of glycol and other additives.
-It has a high boiling point so that it can withstand the heat generated by the brakes.
-Brake fluid should be changed every few years to prevent it from becoming contaminated and ineffective.
