Not being anal, even though I am at times! get some rubber lined p clips, that plain one will chew through that wire loom pdq.
I like nice tidy stuff and when I see nice things like yours the extra effort makes all the difference, not many will even notice it, but you will get some serious respect from those saddos that do.
If you search there is a correct pedal beight to be set, it is something like 150mm top of pedal vertically down to the floor, adjusted by the bolt at the front of the brake box.
Then adjust the master cylinder free play at the pushrod as detailed by Blackburn above.
Single line system needs everything to be adjusted correctly, and then its pretty damned good.
This bolt in your pic adjusts pedal height
