Although the outer bark of young redbud trees is uniform scaly, gray, the inner bark is rusty red. Inner bark is often visible on the trunks of mature redbuds.
It looks like the reddish inner bark of the tree shown the photo has been exposed, perhaps due to age or abrasion. This probably isn't affecting the health of the tree, but if you are concerned, ask a certified arborist to evaluate the tree's condition onsite.

In any case, the speckles on the leaf shown in your photo suggest minor damage caused by sucking insects--lacebugs, leaf hoppers, spider mites, white flies, aphids, thrips, etc.
