I had a similar problem with a 5K , wich is basicly the same braking system 
.

Brakes binding after a 10 maybe 15 minutes drive .
Problem was heat releated , fi with the AC on , it occured at lot faster , 
in winter it
was almost gone . With the brakes seized ,  a wet cloth around the master 
would release them in a few seconds .
You could even hear the "click" of the master's internals releasing .

Replacing he master cilinder cured my problem , altough the old one didn't 
show
any sign of wear or damage .
I've cleaned it , greased it , degreased it .... never been able to fix it .

So unless you're absolutely sure of your MC , I would say that's the culprit 
.
