Are you leaking brake fluid anywhere ?
If not, it's 100% a brake bleeding problem.
I think I had described the brake bleeding process with the GT1.
In summary, I go to the diagnostic/testing menu of the DSC (ABS) unit and when I bleed a caliper, I open the in and out valves at least 3 times each at intervals of 60 seconds (my compressor and hence brake bleeder are not so fast).
Doing this makes a very very big difference.
It takes time, but the result is fantastic.
