9" vs 10" rear drums

Our 93 Dakota as well as my 95 Jeep Cherokee both have disc up front and 9 inch brakes on the back. It may be that since a majority of the braking is done by the front, Chrysler may have felt 10 inch on the rear were not necessary so you might be OK too. Conversely, an 07 Jeep Liberty we traded in on a '10 Ram both had rear discs. Go figure.
