Brake Fluid for the 2018 Subaru Exiga: What You Need to Know

The 2018 Subaru Exiga, like most modern vehicles, relies on a hydraulic brake system to safely bring the car to a stop. Central to this system is brake fluid, a specialised liquid that plays a crucial role in transferring the force from the brake pedal to the brake components at each wheel. So yes, brake fluid is very much used on the 2018 Subaru Exiga, and understanding its purpose and maintenance is important for keeping your car safe and performing at its best.

Brake fluid works by transmitting the pressure applied to the brake pedal through the brake lines to the brake calipers or drums. When the driver presses the brake pedal, the fluid pushes the brake pads against the rotors or the brake shoes against the drums, creating the friction necessary to slow down or stop the car. Without brake fluid, the hydraulic force needed to activate the brakes simply wouldn't be possible, which means no braking power.

One of the key features of brake fluid is that it has to withstand high temperatures without boiling. When braking, especially during heavy or extended stops, the braking system generates a lot of heat. If the brake fluid boils, it can create vapour pockets that compress under pressure, leading to a spongy brake pedal or even brake failure. This is why brake fluid has specifically designed properties to avoid boiling and keep the braking system reliable.

Another reason brake fluid is critical is that it is hygroscopic. This means it absorbs moisture from the air over time. The presence of water in the brake fluid lowers its boiling point and promotes corrosion inside the brake system. Corrosion can damage the brake lines, calipers, and master cylinder, potentially leading to leaks and brake failure. Because of this, it is important to maintain and replace brake fluid regularly to ensure optimum braking performance and safety.

For a vehicle like the 2018 Subaru Exiga, which is designed for family use and everyday driving, keeping the brakes in top shape is essential. The brake fluid specified by Subaru typically meets strict standards for boiling points and chemical stability, often a DOT 3 or DOT 4 hydraulic fluid. Using the correct brake fluid type is vital as mixing fluids with different specifications can compromise braking effectiveness and damage the system.

When it comes to maintenance, replacing the brake fluid is usually recommended every two years or every 30,000 to 40,000 kilometres, whichever comes first. However, this can vary depending on your driving conditions. Regular brake fluid replacement is a simple yet crucial service that keeps moisture out of the brake lines and prevents corrosion and brake fade.

Brake fluid replacement is not just about changing the liquid. It involves flushing the entire brake system to remove old fluid, contaminants, and moisture. A professional mechanic will pump new fluid through the brake lines and bleed the brakes to eliminate any trapped air. Air bubbles can lead to a soft or spongy brake pedal, so removing them restores firm and responsive braking.

Drivers might notice some warning signs if the brake fluid is low or contaminated. These can include a brake warning light on the dashboard, a soft or sinking brake pedal, or reduced braking performance. If any of these symptoms arise, it is important to have the brakes inspected immediately. Low brake fluid might indicate worn brake pads or a leak somewhere in the system.

In short, brake fluid is a small but vital component of the 2018 Subaru Exiga's braking system. Proper maintenance, including regular fluid changes, helps to keep the brake system functioning safely and efficiently. It's an easy service to overlook but one that pays off big time in peace of mind and safety every time you drive.

So if you own a 2018 Subaru Exiga, make sure to keep an eye on your brake fluid levels during routine servicing, and don't skip brake fluid replacement when it's due. Responsible brake fluid care is one of the best things you can do to keep your Subaru running safely and smoothly for years to come.
