Luke is using the term brothers to mean people who share the same faith. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [were teaching the believers]

Note 4 topic: figures-of-speech / activepassive

ἐὰν μὴ περιτμηθῆτε

(Some words not found in SR-GNT: Καί τινές κατελθόντες ἀπό τῆς Ἰουδαίας ἐδίδασκον τούς ἀδελφούς ὅτι Ἐάν μή περιτμηθῆτε τῷ ἔθει τῷ Μωϋσέως οὒ δύνασθε σωθῆναι)

If your language does not use this passive form, you could state this in active form. Alternate translation: [Unless someone circumcises you]

Note 5 topic: figures-of-speech / activepassive

οὐ δύνασθε σωθῆναι

(Some words not found in SR-GNT: Καί τινές κατελθόντες ἀπό τῆς Ἰουδαίας ἐδίδασκον τούς ἀδελφούς ὅτι Ἐάν μή περιτμηθῆτε τῷ ἔθει τῷ Μωϋσέως οὒ δύνασθε σωθῆναι)

If your language does not use this passive form, you could express the idea in active form or in another way that is natural in your language. If you need to say who would do the action, it is clear from the context that it would be God. Alternate translation, as in UST: [God will not save you]
