RE: [alfa] clutch bleeding, ect.

["Jeff Greenfield" <alfaguy@xxxxxxxxxx>]

Try this when bleeding stubborn clutch hydraulics ... it always has worked
for me. 

Have some one inside the car pump the pedal 3-4 times (slowly), and then
hold the pedal on the last pump while you are under the car. Open the
bleeder screw on the slave, and while the bleeder screw is open, manually
push the piston in the slave cylinder in all the way. This will expel the
fluid and trapped air that is inside the slave. Close the bleeder screw
while keeping the piston pushed in.

Have your assistant pump the pedal several times (slowly), and repeat the
process 3 or 4 times. Be sure to check the fluid level between each
iteration, the reservoir is quite small, and if it goes dry you'll have to
start all over.

HTH,

Jeff

It is......as far as I know, I'm doing everything by the book....there's
just a stubborn bubble or two trapped in there somewhere.

Is the bleeder on the slave at the very top (12 o'clock) when you are
bleeding? If not, you will not be able to bleed out all the trapped air.
I went through 2 quarts of brake fluid before somebody clued me in.

After experiencing what was probably a slave cyliner failure last
weekend in my '87 spider(clutch was VERY stiff once, pumped it, then it
bottomed out---resovoir was empty, hydraulic fluid all over the place),
I bought a new slave, rebuilt the master, and replaced the rubber hose.
Now, I cannot seem to get the system to bleed properly---I followed
the procedure (attach hose to bleed nozzle at slave, other end of hose
in fluid to check air bubbles, open resovoir, pump clutch with a slow
release), and even tried the 'long way' of doing it, by pushing the
clutch, tightening the bleed screw, releasing the clutch, then opening
the screw and doing it over again. I went through an entire large
bottle of fluid, yet I still cannot attain the proper travel for the
slave cylinder....it is about half of what it should be (about 0.25-0.30
inch vs. 0.43-0.47). The pedal still feels a bit soft, so I'm guessing
there's still air in there, but how the heck to I clean it all out????
I've easily flushed the entire system 3 or 4 times, and still there's
air trapped in there.....

Or am I missing something????
Am I using the wrong fluid? Couldn't find the factory reccomended
stuff, so I picked up a couple large bottles of DOT 4 brake fluid....I
can't imagine one hydraulic fluid would be *that* much more compressible
than another.....but I'm running out of ideas....

Any help would be totally appreciated...
