Im not sure what it is called but its what the brake peddle is attached to and runs up and into the engine...WHen i push on the brake, this "metal arm" makes a kinda squeeky noise...Almost like it is kinda loose? The brake isnt loose but I can kinda wiggle the arm back and forth ever so slighty...Is this something that needs to get tightened? or does it just do that..I kinda noticed it since it is so cold outside? Any clues ..thanks
