Another clutch not completely disengaging thread

ozmoparjoe said

Update: I replaced my 3/4" bore 1.25" stroke MC with a new 3/4" bore 1.4" stroke MC and it made absolutely no difference whatsoever, played around with pedal ratios, MC rod adjustments and nothing.
So, what now, should i start looking at pressure plate? Clutch discs?
I have video of it operating but cant seem to work out how to upload.
Please help!

Here's what I'd do. Pull the whole system out, and YES at 69 I know how much work that is. "Jig" it all up so you can manipulate the master, and "rig" a light spring setup so you can monitor / measure the T/O bearing movement. Make damn sure it's bled. Carefully measure the master travel so you know you are getting the full stroke.

There can only be so many answers, in no order:

1....There is air in the system
2...The master is too small in relation to the slave
3...The master is not getting fully stroked regardless of what you are thinking
4...You have a leak (doubtful)?
5....You have a hose "ballooning" and soaking up volume.

Regardless of all the fancy "pedal ratio" it comes down to one thing: Is the master getting fully stroked from top to bottom?
