This is page 42 (Illustration Section 20) from a 1973-79 Ford Cars parts illustration catalog, showing the hydraulic brake system for the 1978 Ford Bronco (figure number P-13371). The exploded parts diagram illustrates the complete hydraulic brake plumbing: the master cylinder and vacuum brake booster assembly (with separate callouts for 6-cylinder and 8-cylinder vacuum hose part 9A474), brake lines and tubes routed along the frame and to the front and rear axles, brake hoses, distribution/proportioning valve, and related clips, brackets, clamps, and fasteners. Lettered detail views (A through E) enlarge the booster/master cylinder mounting, line-retaining brackets, valve assemblies, and the rear axle brake line junction. Each component carries a Ford base part number (e.g., 2140 master cylinder area, 2005, 2A275, 2078, 2269, 2282, 4338, 8287, 4022, 28257, 28526) and hardware/service part numbers with suffix codes (e.g., 382802-S MM-173-JB, 385482-S BB-868-E, 387418-S XX-94-F, 387438-S GG-163-YT, 375610-S GG-213, 385116-S BB-817-CV, 370519-S BB-125, 56725-S B-318-GJ, 56720-S B-318-GD, 383661-S GG-247-B, 383057-S II-61-X, 34793-S X-67-A). A reader can identify part numbers and physical routing/mounting locations for every hydraulic brake component on a 1978 Bronco.
