power bleedin the clutch?
folks......just replaced the clutch slave and attempting to bleed using the power bleeder and hose from RH caliper.
I have it all hooked up but when I loosend the bleeders on caliper and slave didn't see much fluid movement after the hose filled up.
Is there a specific sequence other then building bleeder pressure to 10psi, loosen caliper bleeder then slave bleeder?.....thx

FYI, if your blue hose is old, pressure bleeding may be the last straw; watch for puddles. I bleed at 4-5 PSI.
You can bleed the clutch with the two-man method, but it'll take quite some time. Also, with air in the system, I've found it best to bleed with the front raised and the rear on the ground. That get's the master cylinder pointed 'up' and helps bubbles get out of the MC. Not always practical though.

I started by a quick gravity bleed (open the slave bleeder as you fill the system) and then used a hand pump (MityVac) on the slave bleeder to draw fluid thru the system. I finished off by removing the C clip on the clutch master and giving it a quick "burp'. Works like a charm

You are mixing methods here.
1) You can reverse-bleed by connecting the caliper to the clutch slave cylinder, then press the brake pedal to push fluid through. It goes from caliper through the slave, the clutch line, the master, the blue hose, back to the reservoir.
2) You can power bleed using the bleeder attached to the reservoir, and crack the screw on the slave. Fluid flows from the bleeder to the brake MC reservoir, blue hose to the clutch master, clutch line to the clutch slave, out through the slave bleeder.
3) You can reverse power bleed by connecting the power bleeder to the bleeder on the slave cylinder, through the slave, the clutch line, the master, the blue hose, back to the reservoir. Grab a turkey baster and put a plastic-bag shield under and around the reservoir. Slurp some fluid out of the reservoir to make room for the new fluid you are pushing up from the slave.
The method you describe is doomed because there's nothing to push fluid through. You have the power bleeder attached to the reservoir, pressurizing both the source and destination to the same head. So no flow. Add the motive force of your foot on the brake master cylinder, acting as a circulating pump, and you'll have flow. Remove the power bleeder, and you'll reduce pressure and along with it a chance of making a bigger mess if a hose pops off under that pressure.
HTH!

that's the method, given its all set up I'll head back to garage

that worked well:
attach a clear hose from the rh front brake caliper bleeder and the clutch slave bleeder. Crack both bleeders then inside car push the brake pedal repeatedly with the clutch pedal in the up position. I pushed on the brake pedal a dozen times or so then tightened both bleeders before trying the clutch pedal which then worked perfectly.
hope this helps others

What a great writeup.
That page has so much good information.
