Activa 5G front tire jammed

Recently I was driving my Activa and met with an accident. Suddenly the right side break isn’t working ( it is going all the way in unlike normal) and the front tire was also jammed. So i could start the engine easily but the my scooty would just go straight after a lot of acceleration. Please someone explain what has happened so that i don’t remain restless.
Thanks :slight_smile:
