(verify printed p.281) — this line-identification list reads inconsistently for a diagonal-split hydraulic circuit: it labels two “Master Cylinder” ports (Front/Rear) and a “Proportioning Valve (Rear Brake)” line, but only front-brake (LH/RH) lines and no explicit rear-brake (LH/RH) lines. Either a rear-brake line pair was lost to OCR, or “Master Cylinder (Rear)” and “Proportioning Valve (Rear Brake)” together stand in for the rear circuit. Confirm the full line routing against the source figure before use.
