I have an 05 Saturn Relay with 47000 miles and I am getting the normal "disks are warped" pulsation when applying the brakes. I have front and rear disks, so how do I determine which disks need replacing? There is not much pulse in the steering wheel, which makes me think it is the rears. But at 47000 miles, how can I need rear brakes already? Are there issues with calipers?
Any help would be appreciated.
Thanks
