What is Brake Fluid?

Sometimes called hydraulic fluid, brake fluid is the force that’s sent through the brake lines each time you step on the brake pedal in your vehicle. It acts as both a lubricant and coolant for the parts of the brake system.

As you depress the brake, the fluid is pushed through the lines into the brake cylinder where it compresses the piston. That action forces the rotor and brake pads to engage, which creates the friction that slows or stops your vehicle. That friction between two metals creates extremely high heat, and the fluid helps to keep the temperature constant, so the parts don’t overheat. It also lubricates the parts, helping to preserve them for as long as possible.

Your vehicle’s brake fluid should not run low. If it has, I could mean the pads need to be replaced. Stop by Hendrick Dodge's service center when you’re in Cary and speak with one of our technicians. We’re here to assist you.
