The Clutch Master cylinder really did not need replacing. I did
it as a preventive measure. OOPs, forgot to
start taking pictures from the beginning.
Oh well, we join the following program already in progress.....
I had replaced the slave during a previous project.
 The same tear down is needed
as when the INFL REST sensor
was
reworked last week.
|
 You will need to pull the
driver side knee bolster off.
|
 Access is needed in here
to pull the master cylinder
push rod off
of the clutch
peddle. The box on the right
is the head unit for my 10 CD
changer.
|
 The push rod in held in place
by the J-clip above. A tricky
part
to get back on in such
tight quarters.
|
 The above is a view of the
clutch peddle switch and
the tail end
of the master
cylinder push rod to the
left of the switch. ( you
probably should look at
this picture upside-down
since that is how it looks
when you have your head
in there.)
|
 Above is on of two bolts
that hold the back plate
of the master
cylinder to
the fire wall. Note the
tapered end. This is very
handy when reinstalling.
The nuts these go into are
captive and will not spin
and are
located above the
drivers foot area.
|
 The old one is out. (sorry missed
some detail shots here) Missing
from this photo is a very thick
plate (1" or so) that slides over
the large black rubber seal shown
on the push
rod. The two holding
bolts go through this plate.
|
 You can just make out
the plate behind the new
master clutch
here.
|
 Side view of new master
cylinder. Note that on the
old one
several pictures
above, there was a tie
wrap holding the white
plastic reservoir in place.
There in no such hole to
host the tie wrap on the
new one.
|
 Another view of the new
part in place.
|
 Now ready to affix the
fluid line going down to
the slave
cylinder.
|
 This is an attempt to get
a shot of me putting the
J-clip back in
place. It
is hard to see this here
and even harder to take
the shot!
|
 And now to fill the thirsty
reservoir .
|
 Using genuine GM fluid.
It is suppose to prevent
squeaking that
would
occur if regular brake
fluid was used.
|
 Why type a part number
when you can just take
it's picture?
|
 All full. Kinda piss
yellow ain't it?
