Most vehicles are equipped with a hydraulic brake system that multiplies the force that the drivers apply on the brake components to ensure maximum stopping power.

A hydraulic brake system is powered by brake fluid. Once the brake fluid is lost or the fluid is partially displaced by air, the vehicle’s stopping power is lost. That is why it is necessary to ensure that your car’s brake fluid level would never reaches below the minimum.

Frequently Asked Questions

Will brakes work without brake fluid?

Absolutely not! Brake fluid is the force transferring the “middle man” between your brake pedal and your brakes. The pressure you apply with your pedal is carried through the fluid in the brake lines to push against the pads. Without this fluid, your brakes won’t work.

How often should you replace brake fluid?

It’s safe to say that you should change your brake fluid every two years across the board.
