    Exploded view of the power brake unit assembly. Shows the master cylinder mounted to the brake booster (power brake unit), with vacuum hose with check valve, proportioning valve, brake pipes, clevis pin, gasket, and fluid level sensor connector. Numbered callouts 1-8 identify components. Letter callouts (A) and (B) appear near torque-stamped fasteners. Tightening torques are shown in N·m (m-kg, ft-lb). An SST marker appears at the bottom near the proportioning valve fitting. REPLACE notes mark two flare-nut fittings.
