Hi All,
I just joined this site this morning after a frustrating evening of replacing the clutch master cylinder and not having any pressure in the system because of air in the lines.
I searched through and read a bunch of threads about others having problems bleeding the system too so I wanted to pass along what worked for me.
Bench bleeding the master cylinder before installation probably would've worked well but I already had the new one installed and I wasn't exactly sure how to bench bleed it anyway . One thing I found out today is that the cylinder needs to be upside down (hoses up, opposite of the installed position) in order for the air to effectively be expelled (I guess that's obvious once I figured it out ).
With that in mind, once the hoses are connected to the slave cylinder and the reservoir, you can push the cylinder into the pedal compartment but don't connect it up. Hold it with the push rod down and by hand go through the bleeding process. You to wrap the end of the push rod or it hurts your hand. The air should expel very quickly and then connect it to the clutch pedal.
Unfortunately I had to do all this by myself and got a little creative. I took off the wheel and the wheel well so that I had clear access to the tranny and master cylinder. Laying on the ground with my head facing towards the front and the master cylinder out in the engine compartment. I was able to hold the cylinder up side down (hoses up) and pull down with my right arm to acuate the cylinder and operate the bleeder valve with my left hand. Took and little while to get that stuff apart but once I got it taken apart it was very easy and the air came flying out immediately.
Sorry for the long post, just wanted to pass that along since I read so many threads about people having problems.
