Re: clutch bleeding

["Dean W. Cains" <dwc@domain.elided>]

Hi Graham:

Stop by any place that sells home aquarium supplies.  Grab a length of 
silicone (much more flexible and stretchy than the usual vinyl) airline 
hose, and a one-way valve (also called a check-valve) for it.  The length 
of hose and the valve will each set you back just a few $.  I actually like 
this method better than using the SpeedBleeders I have on my '74 
Spider.  It also helps to put a few wraps of Teflon plumber's tape on the 
bleeder screws, to seal any air leaks during the bleeding, and to keep them 
from ever rusting in the calipers.  The absolute best, and quickest, method 
is with the Motive Products Power (Pressure) Bleeder.

For Dave:

Yes, gravity bleeding works fine on the clutch hydraulics.  Just make sure 
the slave cylinder is rotated in its sleeve so the bleed valve is at the top.

Regards,

Dean
