if the shoes got wider then probably the wheel cylinders or the backing plates are different too. maybe something to check.
if you were to prioritize a brake upgrade the first thing on your list should possibly be a dual system master cylinder. even a concours judge would probably not fault you for that one because it is a safety item.
below is a link to a page with possibly a good read for those contemplating a brake upgrade (and other great brake info). bigger isn't always better unless the whole picture is looked at. its all about bias from front to rear. since a lot of us have modified our rides the stock bias pattern could be out the window so an adjustable proportioning valve could be in our future. that is a great reason to use the tech line from the supplier/manufacturer of our choice. rear wheel skid ain't your friend. trucks are light in the rear to start with so, unless you upgrade for load capacity, be aware that a larger brake surface out back also impacts what's going on up front. and vice versa. this is why some of the newer trucks have that load valve at the rear. more load meant more brake pressure to the rear. less load, well you get the idea. it was a valve connected to a link from the rear axle. axle moves away from frame-less brakes and wheel lock up. axle closer-more brakes
