I've posted the article on how to change your brake fluid. Many thanks to Tom Simmons!
Enjoy!

Good one, thanks Tom and K-manS.
The article link probably needs to be updated.
Done, link fixed for new site.
Indeed!

The Chassis Service Manual (Group 4) gives the brake bleeding procedure, which is standard and matches up to the article. After the bleeding is completed, the manual says:
"7. Also drain off some brake fluid at the bleeder valve of the clutch slave cylinder."
I've never heard of this. Anyone know what that is all about?
Another interesting thing is that the manual uses the pressure bleeding technique using 2 bar of pressure, which is about 29psi. I faintly remember various pressure bleeding articles I have read recommending 15psi max. The instructions on my Motive PowerBleeder say 10psi. I would be interested in any comments on this anyone may have.
yz250,
I've used a Motive PowerBleeder for several years. The primary reason for keeping the pressure low is that on many vehicles, the brake fluid tank is attached to the top of the master cylinder with a pressure fit O-ring that sort of snaps into place. You'll make a big mess if you apply sufficient pressure to pop the tank off the top of the master cylinder! No serious damage, just nasty paint eating brake fluid everywhere.
Regarding bleeding the clutch slave... Most cars share the reservoir between brake and clutch. The idea here is simply to purge the old fluid out of the clutch system while your at it.
I've been purging/bleeding brakes on my BMW 328i (track toy until CS arrives next month) 3X/yr for 5+ years and have never messed with the clutch slave cylinder. The systems are only connected at the reservoir, so there is zero possibility of getting air from one system into the other.

I have only used the vacuum fluid extractor from Griot's Garage. It's a one person effort.
You just put new brake fluid in the bottle. Hook the hose on the extractor to a bleeder valve and open the valves until new fluid is visible in the hose.
I haven't changed the fluid in my CS yet, but it has worked on the rest of the fleet.
The article here is well written, for those that have that type of equipment.
