Alright I changed my driver side cv joint already because it was leaking and clunking while making left turns. So anyway rule that out...

Happens sometimes when I hit the brakes I hear a banging sound coming from the brakes I think?(front end 100% sure)

What parts that can cause banging sounds when the brakes are applied?

I thought it was hitting my 17inch rims but couldn't be.... I cannot figure it out what it is...

Also when its a cold day after I pull out of park I feel resistance on the brakes like they were dragging but after a couple of stops it goes away... is this normal?

Another question... I was working on the maxima with my friend on a inclined driveway (pretty steep)... I even pulled the E-brake up but the car still slide forward after I released the brake pedal. Alright so after I was done I try and backed out and when I put the car on R(the shifter was extremely tight) there was a loud bang sound..my question is... did I damage anything on the tranny? because that scared the **** out of me... I thought I pop something.

thanks guys
