Good, it turns out that I have been observing how the direction of my Seat Ibiza gives as "small pulls", I even believe that when stopping in curves it hardens and stays as fixed, I have consulted with the occasional mechanic and they tell me that it is most likely that it is a failure in the battery or alternator, since this vehicle mounts electro-hydraulic
If it is electro hydraulics, you can have a current problem, but I do not think it is alternate or battery, because it opened other components that would fail, the electronic command connection, look here in Chile the Hyundai have that problem as it is expensive repair it and I eliminate them and they leave them mechanical are softer than if only the cancellations, or adapt a hydraulic.
