What Does Brake Fluid Do?

Also known as hydraulic fluid, brake fluid is the force that moves through your vehicle’s hydraulic brake system. The fluid provides the ability to keep a constant temperature when you’re braking. It also serves as a lubricant for the various parts.

As you depress the brake, the fluid is pushed through each of the four brake lines. From there, it goes into the cylinder, which creates the action that compresses the piston. The piston’s force creates the action that pushes the brake pad together with the disc. The pad and disc create the friction that allows your car to stop. It also creates very high heat. The fluid is necessary to keep the system from overheating.

If you notice that your brake fluid level is low, it may indicate that the pads are worn, time for service. Feel free to stop in to Mills Motor Inc. when you have any questions. We’re here to help keep you safe on the road.
