I recently got my car back on the road and first thing i discover was that the brake on the left front wheel was locking up. so, i buy some new hoses, new calipers, and new pads. me and a friend spend half of the day changing the caliper on the left side and now it brakes like it should (gonna do the right front tomorrow) but now, there seems to be a new problem. while driving, if i turn left, there is a loud rattle and some vibration around where the gas petal is, if i go right, it's on the passenger side.

this was our first time changing the brakes on a car, but we went by the Hayne's book and called a mechanic when we needed more info/advice. it wasn't rattling like this before. can anyone tell me whats going on?

EDIT: i'm a tard for spelling brake wrong in the thread title

EDIT 2: well, i managed to fix it on my own, but thanks anyway guys.
