Having a few problems with my braking system. first of all, my ABS light will come on from time to time. it stays on for a few days at a time, then goes away for a while. i had to make a pretty quick stop in the rain and didn't lock up, so i assume the system is still working. second issue is that when i brake, the whole car rattles like crazy hell. what could cause this? i'm completely clueless when it comes to these types of things.
