quick question, rattling and vibration Options

[Lil_Bit_1988]

My car has a very loud rattling sound when i step on the breaks, it sounds as if its coming out from under the hood. It also has a very tense vibration to it when its in idle.

I was told a simple tune up would fix the vibration and a whole new break system would fix the rattling. well i got a new break system and my car was tuned up some where close to about a year ago and the problem still exist and seems to be getting worse.

I was just wondering if anyone would know what it could be and if its going to be a simple cheap fix? Any advice would help.

Thanks
