Narrative:

During departure lost 'B' hydraulic. Ran checklist. Returned normally to airport. On T/D checklist called for second officer to open 'brake interconnect.' he opened 'hydraulic interconnect.' resulted in large loss in braking capability at a greatly increased T/D speed. Checklist and nomenclature should change name of components to provide greater distinction.
