Brake Fluid and Maintenance for the 2017 Lexus IS

The 2017 Lexus IS, like most modern vehicles, relies on a hydraulic braking system where brake fluid plays an essential role. Brake fluid is a specially formulated liquid that transfers the force from the brake pedal through the brake lines to the brake pads and discs, enabling the vehicle to slow down or stop effectively. Without brake fluid, the braking system simply would not function, making it a crucial component for safety and performance.

Brake fluid in the 2017 Lexus IS is a type of hydraulic fluid that operates within a closed system, ensuring that when the driver presses the brake pedal, pressure is applied evenly to the brake calipers at each wheel. This fluid needs to have specific characteristics: it must be incompressible, able to withstand high temperatures without boiling, and resistant to moisture absorption to maintain braking efficiency and safety. Toyota and Lexus typically recommend using DOT 3 or DOT 4 brake fluid for this model, both of which meet these criteria.

One important thing to know about brake fluid is that it is hygroscopic, meaning it absorbs moisture from the atmosphere over time. This moisture absorption can reduce the boiling point of the brake fluid, leading to potential brake fade when the brakes get hot, especially during intense driving or in heavy traffic conditions. This is why brake fluid should not just be topped up when it's low but completely flushed and replaced at recommended intervals.

On the 2017 Lexus IS, Lexus recommends brake fluid replacement every two years or 30,000 kilometres, whichever comes first. Regular replacement helps maintain the fluid's boiling point and prevents corrosion inside the brake system, which can lead to seal damage and costly repairs. Neglecting brake fluid maintenance can impact braking performance and potentially compromise safety.

When changing the brake fluid on a 2017 Lexus IS, it's important to use the recommended type to ensure compatibility with the system's components. The replacement process usually involves flushing out all the old fluid from the brake lines and reservoirs and refilling with fresh brake fluid, followed by bleeding the brakes to remove any air pockets that could reduce braking efficiency.

Here are some handy tips for keeping the brake fluid and braking system in top shape:

• Understand that brake fluid isn't just a one-time fill-and-forget liquid - it needs attention and regular changing.
• Always use the type of brake fluid recommended by Lexus to avoid corrosion or damage to the braking system.
• Schedule brake fluid checks and replacements as part of your regular servicing appointments.
• If you notice a spongy brake pedal or longer stopping distances, have your brakes inspected as it could indicate brake fluid contamination or air in the system.
• Keep an eye on the brake fluid reservoir under the bonnet. Low levels could signify leaks or worn brake components that need addressing.

Brake fluid is often overlooked by many drivers, but it plays a vital role in ensuring the 2017 Lexus IS can stop safely and responsively at all times. Regular servicing and brake fluid replacement can help avoid brake failure, extend the life of brake components, and ensure optimal performance in everyday driving conditions or more demanding situations.

Overall, brake fluid is not just another fluid in the vehicle, it is a key safety element for the Lexus IS. Making sure it is fresh and at the proper level is essential to keep the car stopping power strong and reliable on Australian roads.
