Thanks for the help!
Im sure it is not seized pivots or tension on the pivot bolts. The brake is actually quite new (>1000km). I think the problem is that the spring deformed plastically (I don´t know how I managed to do this), so it lost its "springness". Im in Chile, so it won`t be so easy to source one... might be cheaper to just get a new brake.
