Rear master cylinder and disc brake

Dear All,
I have carefully read everything written in an other topic by Les that I found, as usual, solving the problems.
I Recon the rear master cylinder (ES) with a new kit with attention to correct positioning of parts.
I Recon the caliper back changing the three o-rings.
I replaced old tubes with new hoses.
I struggled so much to bleed the installation and in the end I succeeded, It would seem that there is no more air emerges from the oil bleed only).
The pedal brakes well but I get the impression that the caliper pads do not successfully end the reopening.
In particular, it seems to me that the External pad close more (brakes more) of the inside and it's quite the same external Pad hard to reopen at the end of braking.
What is the problem?.
Les says it can depend on the master cylinder assembled wrong or too much (or little? I didn't understand) screwed between the two pieces.
Maybe, I've reassembled by screwing one and a half turns into more.
I ask you, as usual, your welcome and necessary opinion merits.
Thanks a lot.
Ciao.
Piero

If the master cylinder half is screwed in too much . The bleed hole gets covered and the caliber will not release.
I suggest that unscrew it 2 turns or back to original the try it.
