How often should the brake fluid be changed in a Nissan Bluebird?

[McNathan]

The brake fluid replacement interval for the Nissan Bluebird is every 40,000 kilometers, using Bosch DOT4 brake fluid. Preparing the oil container: Prepare a container for extracting the brake fluid. It is best to avoid using the traditional method of pressing the brake pedal with your foot, as this method may leave residual brake fluid in the pipeline. Extracting the brake fluid: First, extract the brake fluid from the brake fluid reservoir in the engine compartment, which takes about 10 seconds. Then use the extraction container to remove the fluid and air from the brake fluid lines. Connect the container's hose to the bleeder valve on the wheel cylinder and begin extracting the brake fluid. Adding new brake fluid: While extracting the old fluid, have an assistant slowly add new brake fluid at the filling port. Fill the brake fluid to the appropriate level on the dipstick, close the lid, and start the car to test the brake performance. Press the brake pedal several times. If it feels soft, continue the air bleeding process.
