So after the lift was put on, we notice a lot of bouncing when the brakes were applied. We figured it was due to not being aligned, well it was aligned today and we still have the brake issue. The problem is also not constant, but when it does act up the back end of the truck shakes bad. I called Fabtech and they said the new silverado and new suv's are having break issues and to contact a garage. Has anyone else heard of this?
