The bronze area you are referring to is the "Commutator" located on the "Armature" which is the part the electronic pixies run through to turn the Bendix.

Now, there are tricks to getting the brushes spread wide enough to slip it back onto the commutator which usually depend on small pieces of wire and holding your tongue just right.

The way I always did it was to slide the armature a bit out of the end you took the plate off of and use cut coat hanger pieces to hold the brushes back enough to get the cap back on the armature shaft, then remove the wires and slide the whole thing back together.

You can make little right angle hooks, slide the brush back in the holder, slip the hook into the copper wire on the back of the brush and bend it over the edge of the end cap to hold it. Do not slide it through the spring as that may not hold the brush in the guide.
