I know on the Z it's easier.
best way to do it...
suck out all the old fluid with a turkey baster, remove the resevoir, clean the res with brake fluid, makes it nice and clear again. Then drain the fluid from the mc line and take off and trash the old slave cylinder. install a stainless steet weaved flexible line, and a new slave cylinder, and then fill the res....
let the fluid that you put in the res flush out any old fluid, and then let it keep draining till most of the bubles bleed out on their own. then close the bleeder, and squeeze the plunger on the new slave cylinder a few times to get the bubbles to move back up to the master cylinder...keep squeezing a until no bubbles come out....done.
making a bubble come out on the bottom of a fluid system is stupid...and it never works....better results are had when the bubbles move to the natural direction....
for brakes...I get a long clear plastic tube, and I will suck it out via mouth, but will blow it back thru the system when I can...then get all teh bubles to the MC, and then open the bleeders there, and get a short plastic line, and pump it back to the res. done.
