this is perfect, i did a few google searches and found one or two of these sites.

there is a small conflict between the GZ250 manual and what some sites say. specifically, GZ manual says to "suck up the old brake fluid as much as possible" then add fluid and close up the system, while some other sites say to add the cleaner hose and open the valve then add fluid to the reservoir - pumping the brake (adding fluid) until the fluid is clear and no small bubbles then close the valve, top off the reservoir and close up the system.

I ordered brakes from bikebandit and I'll do the fluid after after new pads are installed.

there is one consistent thing that is mentioned which is that the fluid should not touch anything (corrosive)on the bike (paint, plastic, metal, etc.) attracts water and everything should be clean before starting.
