OK, I needed new front pads for my 2009 Aveo 5 so I bought a cheap set. After only a few hundred miles there was a grumbling noise from the brakes. I thought, oh ****, I should have installed new rotors too. So I bought a pair and installed them.... still got a grumbling noise when I applied the brakes. So I bought a new set of expensive pads and the problem went away. So now my Aveo has brand new pads and new front rotors and I have a spare pair of good, true, rotors with alot of life left to them (they have never been cut). Best of all, they are FREE to anyone who wants to stop over at 4 Townley Ct in Flanders, New Jersey (07836). Just give me call to tell me when you are coming and they will be sitting out in front of my garage! 973-584-8476
