Bendix Hydro-Boost Leak Identification Diagram - Seal Leak Locations (Ford)

This document is a labeled schematic diagram titled "Bendix Hydro-Boost Leak Identification," filed with a 1991 Ford Bronco. It shows a side view of a Bendix Hydro-Boost hydraulic brake booster assembly with arrows and drip symbols identifying the locations where fluid leaks can occur and which seal is responsible. The hydraulic line connections are labeled: RETURN TO RESERVOIR, FROM PUMP, and TO GEAR (steering gear). Potential leak points are labeled by seal name: the SPOOL PLUG SEAL at the top-left of the housing, the PISTON SEAL at the lower front, the ACCUMULATOR SEAL at the bottom center, the HOUSING SEAL where the housing halves meet, and the INPUT SEAL at the pushrod/input shaft end. Drip symbols beneath each location indicate where leaking fluid would appear. The figure carries the identification number H6268-B. A reader can use this diagram to visually match the location of an external power steering fluid leak on a Hydro-Boost unit to the specific internal seal that has failed, aiding in diagnosis and deciding whether to reseal or replace the unit. The document contains no year, model, part number, or torque data — it is purely a leak-location identification illustration, one page of a multi-page Hydro-Boost reference set.
