I guess I am really surprised by the brake fluid replacement requirement. It basically says you have to replace the brake fluid every 12 months! That seems pretty excessive to me. Anybody else?
Alcohol-based hydraulic fluids (including brake fluid) absorb water and must be changed unless it's used in an airtight system - and brake systems are not airtight.
The good news is two-fold: 12 month changes is ONLY for severe service, and we don't need special tools to change the Leaf's brake fluid.
The service manual shows the entire process. It's as easy as getting a piece of plastic tubing, a small container, a fresh bottle of the proper fluid, a helper, and a small box wrench to open/close the bleeding nipple on the brake calipers. We don't need electronic tools for our ABS system like other cars - Nissan did a good job here!
I schedule the fluid change to coincide with rotating the tires. I'll raise the car and put on jack stands, remove all four tires, then sit comfortably in the wheel well while bleeding all four corners. DIY isn't everyone's cup of tea, but if one wants to take an hour or two, they can completely replace the fluid for a couple of bucks.
