If I plan to file for bankruptcy Chapter 7, will it eliminate all my debt?

I have 4 assign cards…Ive schooled which if i record for failure section 7 it module execute every my debt. Out of my 4 assign cards usually the single is maxed out…and given every my debt module be eliminated, can i max out my 3 deciding assign cards as well as still get which debt privileged prior to i go for bankruptcy? Also, I’ve schooled which if i own the car as well as cant compensate for it, if i record for bankruptcy, the process association cant hold my vehicle. So what would occur if i acquire the car to financial now, afterwards record for bankruptcy?
