Clutch Bleeding Help! OK So I recently installed a new clutch, flywheel, slave and master cylinder. I am trying to bleed the system now but it doesnt want to bleed at all. The pedal goes all the way to the floor with no resistance, and the new master isnt drawing very much fluid out of the reservoir. I think it may be a problem that I did not bench bleed the master before I installed it. Would this cause the lines to have alot of air in them and not bleed? If I have to pull it out again (3rd time ugh!) what is the proper way to bench bleed the master? Thanks.
First off, clutch bleeding is a two man job. You need one person under the
car, and one person in the car. Step one, feet off the pedal, and the Master
cylinder topped off with fresh clean fluid. There is no sense in filling
the system with dirty contaminated fluid. So, clean out the master cylinder
and put in fresh fluid if you have not done so already.
Secondly, the person under the car will crack open the bleeder screw on the
slave cylinder. The person in the car will then depress the clutch pedal to
the floor and will hold it to the floor. It is very important to not to let
the clutch pedal off the floor at this point, as you will pull air back into
the system. Once the pedal is depressed and held down, the person under the
car will then close the bleeder screw. You may need to pull the pedal off
the floor, or pump it up just a bit to get the pedal back.
You may need to repeeat this procedure 4 or 5 times to remove all air from
the system. Each stroke moves about 10ml of fluid. So, you want to make
sure you don't run the master cylinder dry while you are bleeding the
clutch. What you DO NOT want to do is to pump the pedal, hold it down, and
then crack the bleeder screw. This is the wrong way to bleed the clutch,
and you will never remove any air from the system this way.

What about the bench bleeding issue? I know it came bench bled but I'm pretty sure that with all the finagling I had to do to get the damned thing in there that the fluid in the line dripped out. Should I have to pull it and re-bench bleed it or just try it like that. At this point I just want enough pedal to be able to drive it to the damned dealership and have them deal with it via a powerbleeder.

This moves allot of fluid so you must refill it after doing it twice.
Then bleed as I stated before.
There is no need for a power bleeder.
