Parts for your 2017 Subaru Outback-Brake fluid

Understanding Brake Fluid and Maintenance for the 2017 Subaru Outback

The 2017 Subaru Outback definitely uses brake fluid as a critical part of its braking system. Like most modern vehicles, the Outback relies on brake fluid to ensure that the brakes operate smoothly and safely. Brake fluid is a hydraulic fluid that transmits the force from the brake pedal to the brake calipers or drum brakes, which in turn press the brake pads or shoes against the rotors or drums to slow down or stop the vehicle.

When you press the brake pedal in a 2017 Subaru Outback, the system channels brake fluid through a series of brake lines and hoses to activate the braking mechanisms at each wheel. This hydraulic pressure system is what makes braking efficient and responsive. Without brake fluid, pressing the brake pedal would have no effect, and the vehicle would not stop properly.

The brake fluid used in the 2017 Outback is typically a DOT 3 or DOT 4 type fluid, which meets strict specifications for boiling points and moisture resistance. Using the right type of fluid is essential because brake fluid operates under high temperatures and pressure, especially during heavy braking or driving in mountainous areas. The exact fluid type and specifications can be found in the vehicle's owner manual or service guide.

Brake fluid also serves a couple of other important purposes. Firstly, it lubricates internal components within the braking system, helping to reduce wear and tear. Secondly, it protects the system by preventing corrosion of metal parts. Since the fluid is hygroscopic, this means it absorbs moisture over time from the air, which can reduce its effectiveness and cause internal rust or corrosion. This is one of the reasons why brake fluid needs regular checking and replacement.

For Outback owners, keeping the brake fluid fresh and at the right level is a key part of routine vehicle maintenance. Over time, as the brake fluid absorbs water, its boiling point drops, which raises the risk of brake fade. Brake fade is a decrease in braking power that happens when the fluid vaporises under heat, leading to a spongy brake pedal or even brake failure. This is a safety hazard that should never be ignored.

Subaru generally recommends changing the brake fluid every two years or around 30,000 kilometres, but it's a good idea to check the owner's manual or have a trusted mechanic inspect it regularly, especially if the Outback sees heavy use. For drivers who do a lot of towing, off-road driving, or frequent long descents, inspecting the brake fluid should be part of a more frequent service schedule.

Replacing brake fluid is not a difficult process for a mechanic but it's not something typically suited to DIYers without the right tools and knowledge. The process usually involves draining the old fluid, flushing the brake system, and refilling with fresh brake fluid to ensure that no air remains in the brake lines. Air bubbles in the hydraulic system can cause brake pedal sponginess and reduce braking efficiency, so a proper bleed and refill is important.

Regular brake fluid maintenance also helps protect other brake system components, including the brake master cylinder, calipers, and ABS (anti-lock braking system) components. Since the 2017 Subaru Outback comes equipped with ABS as standard, keeping the brake fluid in optimal condition ensures these safety systems can function correctly when needed.

If the brake fluid level is low, it's often a sign of worn brake pads or a potential leak in the brake system. It's wise to have the whole system inspected rather than just topping up the fluid. A low brake fluid level can negatively affect braking performance and is a warning sign that servicing is needed.

Some other tips for Outback drivers include:

• Check the brake fluid reservoir occasionally to ensure the fluid is at the recommended level and looks clean. Cloudy or dark fluid usually indicates contamination and the need for a change.
• Have the brake system professionally inspected at every scheduled service, even if there are no apparent issues with the brakes.
• Use only the brake fluid specified by Subaru to maintain system integrity and warranty compliance.
• Be aware of how the brake pedal feels. A soft or spongey pedal can hint at air in the lines or degraded fluid.

Ultimately, the brake fluid in a 2017 Subaru Outback plays a vital role in making sure the vehicle brakes safely and reliably. Regular maintenance and timely fluid replacement protects the brake system, preserves vehicle safety, and helps maintain optimum driving performance. Taking care of this often overlooked fluid means the Outback can continue to handle Aussie roads with confidence and control.
