It's natural for the seeds, or red wings, to dry up and turn brown. It does not indicate a larger problem with the tree.
Many trees by late summer have some brown spots on the leaves. This could be caused by minor fungal disease infection, insect damage, environmental damage, etc. If it's limited and isn't causing leaf drop, then there isn't anything to worry about.
