Subject: <E30> Clutch hydraulics postgame report
Two weeks ago, I posted asking for advice on jackstand location for
my 325e (Helga), and received great advice... Last week, the parts
arrived in the mail and I had a day free to get dirty with the car, so I
walked out to the garage to replace a BADLY leaking, but functioning clutch
I decided to move the car into the center of the two-car garage to give
myself a little bit more working space, until I discovered that the clutch
pedal was resting on the floor with no pressure. Luckily, I had ordered
a clutch master at the same time...
The removal of the slave was easier than I expected, but the master
was a real PITA. Primary problem was the threaded fitting in the engine
bay (far end of the unit). It is (um, to say the least) difficult to get
a wrench on that puppy.
I noticed that the Bentley manual cautioned against pressing the
clutch pedal with the slave removed from the car, so naturally that is
exactly what I did in a moment of utter stupidity... After disassembling
the (new) slave cylinder, I realized that I'd need a another one to
Installation of the master cylinder was a utter nightmare, with the
exact same threaded fitting refusing to line up correctly. I loosened
everything in reach, begged, swore, screamed, took long breaks to calm down,
etc. After roughly 2.5 hours of futile labor, I was finally able to
out-wit twenty grams of metal and it spun into place with no problem.
Someone on the list suggested disconnecting this exact line from the
other end (looks much easier) and I tried that first. The easy end of the
line is now horribly stripped from my efforts (frown).
Next day, a quick trip down to Clearwater, FL and site of
EuroProducts, and I had another clutch slave in hand. I had no idea that
Europroducts didn't expect to do any over-the-counter sales, and I must say
that they looked shocked when I wandered in the (front/back?) door. After
explaining what I needed, they were happy to help me, though. Maybe
next time I'll just go to a dealer (~20 miles closer) when I need parts in
a hurry. (Famous last words) "The dealer can't be THAT much more
expensive, can they?"
The new slave cylinder practically popped right into place, and I
proceeded to change over to ATE blue brake fluid and bleed the system.
Remembering the advice of the net, I tried to avoid pressing the
brake pedal all the way to the floor while manually bleeding the lines, but
I still heard an occasional grinding noise... It's probably a bad sign, and
I expect to be replacing the brake master cylinder soon...
I think everything works right now, but my clutch still engages a little
bit 'too far from the bottom' for my tastes. I assume that it's just a
personality thing with the car, previous owner claims that the clutch is
less than 30k miles old, no slippage yet, etc.
