[GT Driving Force]{ISSUE} Brake pedal "always active"

[The A.W.G.]

Hi, I have a problem with my GT Driving Force and I'd be really happy if someone could help me. Thanks!

Basically, the brake pedal keeps sending signals to the system, like there is a constant pressure on it, even if I don't even touch it. To best explain the issue, I create a gif image of the Settings view of my wheel profile whilst I was NOT touching anything: http://cdn.makeagif.com/media/2-02-2014/YjDenc.gif

Other related informations that could be important.
This suddenly started happening 5 days ago. Never happened before.
This happens when I press the pedal for the first time. If I don't touch the pedal anymore, the oscillation decrease until it stops. But if I press the pedal again, everything happens again.
The Throttle pedal also has the same problem, even if to a lesser extent.

A big THANKYOU to anyone who will be able to help me on this (even "your wheel is broken buy another" will be of help, if true... at least I'll know ).

is there a way to calibrate it?

Yes but it keeps doing that even during the calibration.
