Brake Fluid and Maintenance for the 2017 Subaru Exiga

The 2017 Subaru Exiga, like most modern vehicles, relies heavily on brake fluid as an essential component of its braking system. Brake fluid is a specialised hydraulic fluid that transfers force from the brake pedal to the brake components at each wheel, allowing the vehicle to slow down or stop effectively. Without brake fluid, the Exiga's brakes simply wouldn't function properly, making it an indispensable part of this vehicle's safety system.

Brake fluid works by transmitting the pressure applied by the driver through the brake pedal to the brake calipers or drum brakes at the wheels. This pressure forces the brake pads or shoes against the rotors or drums, producing the friction needed to slow the car down. The fluid must be able to withstand extreme conditions because braking generates a lot of heat, and inconsistent fluid performance can result in poor brake feel, reduced stopping power, or even brake failure.

Typically, the brake fluid used in the 2017 Subaru Exiga will be of the DOT 3 or DOT 4 type, common in many passenger vehicles. Both types are glycol-based fluids with high boiling points, necessary for resisting the temperatures generated during heavy braking. DOT 4 has a higher boiling point compared to DOT 3, which helps maintain performance in more demanding conditions.

One of the key things to understand about brake fluid is that it is hygroscopic. This means it absorbs moisture from the air over time and from any moisture entering the brake lines via seals or openings during servicing. Moisture contamination lowers the boiling point of the brake fluid and can cause corrosion inside the braking system. This is why regular brake fluid replacement is important - not just to maintain optimum braking performance but also to protect the internal components of the brake system.

When it comes to servicing the 2017 Subaru Exiga, maintaining the brake fluid is a crucial part of routine maintenance. Subaru recommends checking and replacing the brake fluid at regular intervals, often suggested every two years or every 30,000 to 40,000 kilometres, whichever comes first. However, conditions such as frequent hard braking, driving in hilly terrain, or exposure to humid environments might require more frequent checks.

Changing brake fluid isn't just about topping up the reservoir. The process involves completely flushing the old fluid out of the brake lines and replacing it with fresh fluid to avoid contamination. This gets rid of any moisture-laden fluid that could cause problems down the track. When performed properly, brake fluid replacement helps maintain the brake pedal's firmness and responsiveness, ensuring the Exiga's braking system works safely and efficiently.

During fluid replacement, mechanics will typically bleed the brakes to expel any trapped air in the system. Air bubbles can compress under pressure, making the brake pedal feel spongy and reducing brake effectiveness. Fully bled brake lines restore consistent hydraulic pressure, which is critical for predictable stopping power.

For Subaru Exiga owners, using the right type of brake fluid and adhering to maintenance intervals is paramount. Using the wrong fluid or neglecting regular changes can cause damage to rubber seals and hoses inside the braking system, potentially leading to leaks or component failure. Also, contaminated brake fluid can impair the anti-lock braking system (ABS) or other electronic safety systems, which are designed to enhance vehicle control during emergency manoeuvres.

It's also worth noting that brake fluid should always be kept sealed and stored properly because of its tendency to absorb moisture from the atmosphere. Once a bottle is opened, the fluid can degrade fairly quickly if not used promptly. Therefore, when servicing the brake fluid on a 2017 Subaru Exiga, it's best to use new, unopened brake fluid that meets the manufacturer's specifications.

Regular brake system inspection including fluid condition is a smart move for any vehicle owner, and the Subaru Exiga is no different. Brake fluid topping up or replacement is an affordable and straightforward service that can prevent costly repairs or safety hazards. Whether for daily city driving or adventurous road trips around Australia's varied landscapes, well-maintained brake fluid contributes significantly to the safe operation and peace of mind behind the wheel.

So, while brake fluid might be one of those less glamorous parts of a car, it definitely deserves attention. For 2017 Subaru Exiga drivers, keeping an eye on brake fluid condition and scheduling timely changes as part of regular servicing helps keep those brakes working just as Subaru designed them to - reliably, smoothly, and safely every time the pedal is pressed.
