I figured ill try again since no one decided to answer my question before. Yesterday i noticed out of no where a hum when im going around curves to the right. Its not all the time only when slightly turn right. Now i noticed there is a 205 in rear insted of a 195 dont think that has anything to do with it. When i step on the brake it will hum louder or sometimes just go away until i turn slight right again. Rotors are brand new all the way around including pads all sq-eek cheap pads. Now the e brake does not work at all i noticed that when i pull it up and release it i get a like a grind when brakes go bad. When i pull it up again and down it goes away. What can this hum be im so confused. No leaks no smells nothing like that.

I don't think the brakes are contacting anything - though they may change the load on the wheel bearing.

It sounds like you have a wheel bearing going bad in that corner.

I would guess the bearing on the left side, but perhaps you can verify by listening in back with someone else driving?

Jack the car up and spin the wheel.

Uhhhh...

That's not speed related. The noise doesn't change at all.

Axe the wheel bearing theory.

Is that the fuel pump???

Haha i don't know I can't see it being a wheel bearing because its not constant but just now I noticed when I'm parked a lul bit uphill or down and in in neutral car don't roll and when I accelerate a bit it won't roll freely only after I start driving it will loosen. Oh yeah my ebrake don't work either
