Brakes problem
2003 Ford Windstar 6 cyl Front Wheel Drive Automatic 134,00 miles

trying to figutre out what causing it to shimmy had new rear brakes shoes wheel cyl and drums 2 months ago and every thing was fine ... about 2 weeks ago it started to shimmy hard when slowing down from hwy speeds but the drive normally is very smooth and quite
retated tires and that didn't make a difference, changed the from rotors pads and calipers and still nothing then I tried another set of rear drums and still no change ???????
front end all seem to be tight also
