Before I go on with the story, I have 2004 530i.

The dealership is really far away from me, so i took my car to my local specialist to change my brakes.

After he changed my brakes, my car starts to shake like crazy on my left side whenever I step on the brakes.
So I told him what happened, and he said it might be warped. It was warped, and he changed for me. Now the braking shake is gone, whenever I'm driving I can feel vibration on my left side still. I did my alignment, change my tires, check for bent rims, it still shakes!!!
I took my car to him again and he said it drives fine. What is going on???? Is it because he didn't install the rotor correctly?
I feel the vibration mostly where my gas pedal is, the wheel vibration is very subtle.

Should I get these and replace my current rotor??

It might bad balancing...
did you bed in your new brakes properly?

Bad balancing of..what?

The brakes that he put it on for me are so spongy. It doesn't it brake properly, it's like he put civic's brake pads on to my car. It doens't really stop1!!

I actually bought the brakes and the charcoal cabin filters from this seller on ebay last week. So far no issues, they also came within 5 days from California to New York. If that helps you out.
