Spain had plenty already.

But the treaty of Tordesillas didn't contain even half of current Brazil, as it happens during the Iberian Union everything became a spanish colony, which gave free reign to brazillians and newly arrived portuguese to scatter inland into previously spanish but uncolonized territory.
When the Iberian union ended, this land remained with Portugal.

That's not the entire reason. Spain did want those territories back. But a bunch of dowries were given and things were contained.
This is the reason why Equatorial Guinea was colonized by the Spanish (despite the fact that it's completely under the Portuguese side of the Treaty of Tordesillas).
