Brake fluid is a liquid that is used in hydraulic brake systems. It transfers force from the brake pedal to the brake pads, which then apply pressure to the brake rotor and stop the vehicle. Without brake fluid, your car would not be able to stop!
Brake fluid is a hydraulic fluid that is used in brake systems. It is typically made from glycol or mineral oil, and it works by transferring force from the brake pedal to the brake pads. When you press down on the brake pedal, the fluid is forced through a small hole in the master cylinder.
This pressure forces the piston in the brake caliper to push the brake pads against the rotor. The friction between the pads and the rotor slows down the wheel, and eventually stops the vehicle. Brake fluid is important because it allows your car to stop. However, it can also be dangerous if it leaks.
