I've bench bled both my brand new clutch master cylinder and slave cylinder, installed them, now when trying to bleed its going through the cycles... seems like there is no more air coming through, but after pumping a few times the clutch pedal falls to the floor like its being pulled in.

I've checked for leaks theres no visable leaks anywhere, Im stumped and turned a 30 min job into a 8 hour job trying to continusly bleed ...

could my new master be a faulty one or something? (when bench bleeding it seemed to work fine, as well as the slave)

1996 gsr

 

My guess is one of the cylinders is DOA, [blow-by]. 94

 

There could be a few things related to this problem:
1.Leaks in the line it could be possible.
2.Did you adjust it properly where the cotter pin goes. Usally adjusment has an issue when it doesnt come all the way back so it stay in "Freeplay" mode and acts like a foot excercise machine from hell lol..
3.Faulty Refurbished Master/Slave Cyclinder it happens. They usally just clean it up 2 make it shiny and add new bushings lol. They usally Don't take returns so g/l.

Let Me Know if this work!!!

 

No leaks, I went furthest out, furthest in and in the middle still nothing..
Getting another master tomorrow, I only got the slave because it wouldn't bleed properly after installing master.. I also use a vacuum pump bleeder to bleed so I know theres no air or leaks.
