Well, the subject pretty much says it...one of the anti-rattle springs on the right rear brake setup just broke. Is it critical to have, or can I just leave it out for now (I want to get the rear end of the car back together tonight; if I leave it off, I'll re-do it next time). I'm spraying Permatex Disc Brake Quiet on the back of each pad, BTW...

A quick response would be appreciated. Thanks in advance!
