I think I know what you are refering to, but here's the deal:
To get the lever end off the MC there is a clip, which allows the release of the end of the lever...at this point the only thing holding the lever to the MC is the position adjuster knob/rod...which then enters the MC through a rubber boot to interact with a piston, I presume. This is the part that is holding me up. I have tried pulling the adjuster rod out of the rubber boot with some significant force to no avail...making me thing that brute force is not the answer...maybe it screws out?
