Brake Fluid – What It Does & Why It’s Important

Stop, in the name of love! Being able to stop is crucial when it comes to the safety of your car’s occupants. Read our blog to learn more about what brake fluid does & why it is important!

Brake fluid plays an important role in the proper functioning of your vehicle’s brake system. Working under extremely high temperatures, the brake fluid facilitates the movement of the brake system’s various components. A non-compressible substance that is contained within the brake lines, brake fluid provides the force created when the brake pedal is pressed. This force is applied to each of the brake rotors on the four corners of the vehicle, effectively applying pressure to the wheels to slow or stop the movement of the vehicle.

Brake fluid is an element that needs to be periodically replaced. There are a variety of brake fluid types, so it is important to choose the right type for your vehicle. The primary types of brake fluid are glycol-based and silicon-based fluids. Glycol-based brake fluids are mostly used in vehicles with anti-lock brake systems (ABS) and vary by individual grade options. Silicone-based brake fluids are designed for use in vehicles without ABS technology. If a non-ABS vehicle has ever had a glycol-based brake fluid used in the brake system, that type of brake fluid must be continued since residual amounts of glycol will compromise the performance of a silicon-based fluid. To find out the best brake fluid option for your vehicle, refer to your owner’s manual, or ask your auto service technician.

It is necessary to drain and replace brake fluid periodically because it absorbs moisture from the air and degrades over time. Changing brake fluid at recommended intervals will assure proper brake system functioning. Brake fluid changes are typically done every one or two years, however different vehicles will have different recommendations for best performance.

Since your vehicle’s brake system and brake fluid are so crucial to its safe operation, it is really important to have this service done. It is also recommended that this service be done by a qualified professional automotive technician.
