What German rules say about a Brazilian licence
Brazil does not appear in Anlage 11 FeV. There is no conversion that skips both the theory and practical tests for this country as a whole.
The Federal Ministry for Digital and Transport (BMV) says a non-EU/EEA licence is valid for six months after you establish normal residence in Germany. After that period it is no longer recognised.
To keep driving you need a German driving licence. Because this country is not in Anlage 11, you must pass the German theory test and the practical driving test. Documents and any translation requirement are set by the local Führerscheinstelle.
In exceptional cases the authority may extend recognition by up to six months if you can show you will not have normal residence in Germany for longer than 12 months.
