I read this from another website and I will try to find a link, but the bottom line is this......Your clutch, and brakes share the same fluid, and on our cars share the same master cylinder. Every few months or so, maybe even at each oil change, use a turkey baster syringe to suck out all the old nasty, and probably brown fluid, and top it off with new. Then go for a 5 or 10 minute drive, and do it again until your fluid in the reservoir is reasonably clear. This allows you to remove the abrasive clutch dust from the system without having to bleed it. This also extends the life of all your hydraulic equipment having anything to do with your clutch or your precious Brembos. All this takes about 10 minutes, and costs about $10. Pretty simple math there eh? Here is the link.
