What Is Brake Fluid and What Does It Do?

At some point, you will hear the term "brake fluid." But what is it, and what does it do?

Brake fluid, also called hydraulic fluid, is what makes your car stop when you press the brake pedal. When the pedal is pressed, a piston is squeezed inside the brake caliper, which increases the pressure inside the brake lines. This increased pressure causes the rotors to press the brake pads, which then come into contact with the wheels, stopping the car. The two main types are glycol-based and silicone-based. The first is used in vehicles with ABS.

Brake fluid should be changed routinely based on manufacturer recommendations. You may also notice it's time for a change if your car seems to take longer distances to stop or the pedal feels spongy when pressed.
