So my bike is 6 years old and I just bought it used last Sept. Given the state it was in I highly doubt that the brake fluid has ever been changed. Reading the recent thread about the brakes gave me the notion that I need to change the fluid this spring. I'm not afraid to do the work on my own but I have never had to change fluid on a bike (or a car for that matter which is weird considering how many times I've worked on brakes otherwise) and was wondering if anybody had a link to a good walk-through. Ideally one for the 900 but I reckon any will do since almost all non-ABS motorcycle brake systems are pretty much similar. Unfortunately, I don't have the original manual either so I can't use that to help. Are special tools required on a bike to make sure the system is purged of air? I might ask the father-in-law to lend a hand since he's a better wrench than I am. Thanks for any help as always.
