Once the leaves of a Maple get like that they are not going to recover, that particular leaf is damaged for good. My Maples tend to get a little ratty by midsummer and this year was worse than usual.
Not being from your climate I'm afraid that I can't offer much other than to suggest a more sheltered location. Keep it watered properly but don't try to overcompensate by watering too frequently. You may have to resign yourself to the possibility that you have chosen a species that is ill suited to your climate.
Don't give up on bonsai though, do some more research and try again. We all kill trees. I lost some this year, it happens.
