Brake fluid is a crucial component of any functioning vehicle’s braking system. It is responsible for transmitting the force of the brake to the brake pads or shoes. While it is often overlooked, it plays a major role in ensuring effective braking and vehicle safety.

In this article, we will explore the importance of brake fluid maintenance and replacement, specifically from a qualified mechanic or reputable auto repair shop. We will also highlight important reasons why vehicle owners should never overlook this part of vehicle inspection and maintenance.

The Role Brake Fluid Plays in the Braking System

Brake fluid is a hydraulic fluid specially designed to work under high temperatures and pressures in the braking system. It works by serving as a medium for transmitting the force or pressure applied to the brake pedals, amplifying the forces, and sending them to the brake pads in the front and rear ends of the vehicle, which then stop or slow down the car.

The Importance of Brake Fluid Maintenance

Over time, the volume of brake fluid may decrease. This decrease is quite normal and can be fixed by easily topping the liquid. However, consistent decreases should be inspected and addressed, as they also lead to a decrease in the effectiveness of the brakes. Some reasons why you need to regularly maintain your brake fluid include the following:

• Moisture Absorption: Brake fluids tend to absorb moisture from the air when they are exposed to it. This moisture causes a decrease in the fluid’s boiling point and compromises brake performance. The accumulation of moisture could also lead to damage to critical components of the braking system. Replacing the braking fluid at regular intervals allows vehicle owners to safeguard against corrosion-related issues and prolong the lifespan of their braking system.
• Contaminant Buildup: Brake fluid will accumulate contaminants like dirt, debris, and some metals from other components in the vehicle. These contaminants compromise the effectiveness of the brake fluid, and allowing them to build up could cause potential damage to other braking components. Contaminant buildup can be regulated by regular maintenance and fluid replacement, ensuring that your brakes remain functional at all times.
• Brake Fluid Leakage: Brake fluid will reduce over time if there is damage to the brake’s master cylinder, a failed piston seal, or for other reasons. This reduces the stopping power of your brakes and is usually accompanied by oil puddles beneath your car or overly soft brakes. Regular maintenance ensures leakages are identified and resolved early, preventing brake fade and maintaining optimal efficiency.

The Right Time Interval for Brake Fluid Maintenance and Replacement 

Brake fluid replacement intervals vary depending on the vehicle manufacturer, the driver’s habits, and the usual driving conditions. But generally, you are required to replace brake fluid every 2 to 3 years or after 30,000 to 45,000 miles.

In conclusion, brake fluid maintenance is an important aspect of vehicle maintenance and should be integrated into overall car maintenance habits. It should also be carried out at least once a year at a trusted auto repair shop. Inspecting and maintaining brake fluid is also advised before going on a long trip, when the vehicle has been in a collision, or after a long period of inactivity.
