Linda Thompson asked 5 months ago
I own a 2015 Nissan Pathfinder, and according to the owner's manual, it's recommended to change the brake fluid every second oil change, which is approximately every 16,000 km or 12 months. This frequency seems quite high to me, especially since brake fluid is known for its hygroscopic properties. I'm wondering if this is a standard practice or if it's an excessive requirement.

Hi there, Linda! Thanks for reaching out with your question about brake fluid changes for your Nissan Pathfinder. You're right in noting that brake fluid is hygroscopic, meaning it absorbs moisture from the air, which can lead to reduced performance and potential brake system damage over time. The recommendation of changing your brake fluid every 16,000 km or annually does seem more frequent than usual. Most manufacturers and experts suggest a brake fluid change every 2 to 3 years, irrespective of the mileage. This interval is generally sufficient to ensure the brake fluid stays effective and free from excessive moisture content. However, specific vehicle models might have different requirements based on their brake system design and the type of fluid used. In the case of your Nissan Pathfinder, it's important to consider the manufacturer's recommendation, as they design these guidelines based on extensive testing and knowledge of the vehicle's requirements. For a more personalized approach, you could use brake fluid test strips or a moisture meter to check the condition of your brake fluid. These tools can help you determine whether the fluid needs to be changed based on its actual condition, rather than strictly adhering to mileage or time intervals. Lastly, consider the driving conditions and climate you're in. More demanding driving conditions or humid climates might necessitate more frequent changes. On the other hand, if your vehicle is mostly driven in mild conditions, you might be able to extend the interval slightly. Zack - Motor Verso Mechanics Team
