How often should the brake fluid be changed in a Nissan X-Trail?

[Jonah]

The brake fluid in a Nissan X-Trail should be changed every two years or 40,000 kilometers. Brake fluid replacement for the Nissan X-Trail: Changing the brake fluid in a Nissan X-Trail requires 2-4 liters. Brake fluid has hygroscopic properties, and if not replaced for a long time, it can corrode the braking system, posing a safety hazard. Steps for changing brake fluid: Park the vehicle on level ground, turn off the engine, and open the hood. Use a syringe to extract the old fluid from the reservoir. Fill the reservoir with new brake oil, using a funnel to avoid spilling it onto the engine compartment. Use a jack to lift the vehicle, starting with the rear wheels. Remove the tire and locate the bleeder screw on the brake caliper, then remove the rubber dust cap. Loosen the bleeder screw with a wrench, attach a rubber tube to it, and connect the other end to a drain bottle. Inside the vehicle, start pumping the brakes. If two people are working, one can pump the brakes while the other observes the fluid drainage. Pay attention to the color of the brake fluid in the rubber tube—old fluid is darker, while new fluid is lighter. Once the fluid coming out of the tube is the lighter new fluid, the wheel's fluid change is complete. Stop pumping the brakes, reinstall the tire, and repeat the process for the remaining three wheels. Check the fluid level in the engine compartment reservoir to see if it has reached the lower limit. If it has, add new brake fluid as needed.
