Overbraking is one of the most common rider issues. We all do it to some extent.
You can't pick a good braking marker and work to improve braking skills until you have a really good, workable turn point and entry speeds. When your ready, read
this first (picking a brake marker). Then after having worked on getting your turn points and entry speeds perfect, give
this a read to improve it even further.
Other members have contributed a lot of good stuff on braking as well. If you do some basic searches, it should keep you busy for a while.
