'Abbringen' (to dissuade) is a separable verb. The prefix 'ab-' comes at the end in main clauses. In the infinitive with 'zu', 'zu' comes between 'ab' and 'bringen'.
Ich bringe dich von dieser dummen Idee ab!
I'll talk you out of this stupid idea!
The structure is always fixed: you bring 'jemanden' (someone, accusative) 'von etwas' (away from something, dative) ab. The object of persuasion always appears in the dative after the preposition 'von'.
Sie hat ihn von seinem Plan abgebracht.
She talked him out of his plan.
When the action you want to dissuade someone from is described with a verb, you use the structure 'jemanden davon abbringen, etwas zu tun' (to dissuade someone from doing something).

I was able to dissuade her from quitting her job.
The expression 'jemanden vom Weg abbringen' (to lead someone off the path) can be used literally, meaning to leave a path, or figuratively, in a moral or professional sense. It is often expanded to 'vom rechten Weg abbringen' (to lead someone astray).
Schlechter Umgang hat ihn vom rechten Weg abgebracht.
Bad company led him astray.
