Understanding Brake Fluid for the 2017 Subaru Forester

When it comes to the 2017 Subaru Forester, brake fluid plays a vital role in the overall braking system. Brake fluid is definitely used in this vehicle, as with most modern cars, because it is essential for transferring the force from the brake pedal to the brake pads and discs. Without brake fluid, the hydraulic braking system simply would not work, meaning stopping the vehicle safely would be impossible.

Brake fluid is a specially formulated liquid that is designed to operate reliably under extreme conditions without boiling or freezing. It is critical that the right type of brake fluid be used for the Forester to maintain optimum performance and safety. Subaru typically recommends DOT 3 or DOT 4 brake fluid for the Forester, both of which are glycol-based fluids known for their ability to handle varied temperatures and resist moisture absorption.

The purpose of brake fluid is straightforward but highly important. When you press the brake pedal, the force you apply is transmitted through the fluid in the brake lines, which pushes the brake pads against the rotors at each wheel. This action creates the friction needed to slow or stop the vehicle. Since the brake system is sealed and operates under hydraulic pressure, the fluid must remain incompressible and free of air or contaminants for the braces to respond immediately and effectively.

Over time, brake fluid can absorb moisture from the air, even though the system is sealed. This is because brake fluid is hygroscopic, meaning it naturally attracts water molecules. The presence of water in the system lowers the boiling point of the fluid and can lead to brake fade, especially during heavy braking or in hot conditions. Brake fade happens when the fluid boils and forms bubbles, which compress and reduce the hydraulic pressure. This causes the brakes to feel spongy or even fail temporarily, posing a safety risk.

Because of this, regular brake fluid replacement is a crucial part of maintaining a 2017 Subaru Forester. Most mechanics and service schedules suggest replacing the brake fluid every two years or roughly every 30,000 kilometres, whichever comes first. However, for those who do a fair bit of towing, off-roading, or heavy city driving, more frequent changes might be necessary to keep the system in tip-top shape.

During a brake fluid change for the Forester, the old fluid is fully flushed out of the system to remove any moisture and contaminants. Fresh brake fluid is then filled to ensure the system has the proper hydraulic properties. This routine maintenance step helps maintain braking performance, avoids corrosion inside brake lines and calipers, and keeps all parts working smoothly.

• Check brake fluid levels regularly. Low fluid levels can hint at leaks or worn brake pads.
• Look out for a brake warning light on your Forester's dashboard, which can indicate fluid issues.
• If the brake pedal feels soft or spongy, it might be time to inspect or replace the brake fluid.

Failing to maintain the brake fluid properly can lead to costly repairs down the track. Corrosion caused by wet brake fluid can damage brake components that are expensive to replace. Plus, compromised brake performance affects your safety and that of other road users.

In short, the brake fluid in the 2017 Subaru Forester is a small but mighty part of the overall braking system. Regular inspection and timely replacement ensure the vehicle stops confidently every time the pedal is pressed. Treat brake fluid as a priority during servicing and it will reward the driver with smooth, reliable braking and peace of mind on every journey.
