Without independent solenoid operation, the brushes receive no voltage.

Wrong.
The pull in winding is as shown in Dave's diagram and earths via the main motor circuit ie through the brushes. A hold in winding (lower current) operates in parallel and is earthed directly. When the solenoid contacts close the pull in winding has an equal voltage at each end and so stops operating. The hold in winding continues until the circuit is de-energised.
