1989-1998 Nissan 240SX Factory Brake Master Cylinders and Vacuum Boosters: S13/S14, ABS and Production Branches

S13 booster branches remain separate: non-ABS 47210-42F00 resolves to 47210-42F10, while ABS 47210-58E02 resolves to 47210-58E09. Early S14 manual/non-ABS booster 47210-70F20 resolves to 47210-70F96; the automatic or manual-with-ABS 47210-72F20 resolves to 47210-72F96. Late 07/1996-up S14 uses separate 47210-81F10 or 47210-81F11 branches rather than a universal supersession. Master-cylinder supplier variants and the 07/1996 81F20/81F21/81F22 split are production/equipment choices, not proof of cross-branch interchange. S13 piston-kit chains 46011-01F25 to 46011-44F25 and 46011-41F26 to 46011-44F26 do not authorize reuse of unknown old seals.

Begin with recipient VIN/build, US/LHD S13 or S14 generation, factory manual/automatic equipment and factory ABS status. Photograph the removed master and booster labels/cast marks plus every face and connection. For the master, match exact Nissan or validated replacement identity, supplier branch where cataloged, 7/8- or 15/16-inch bore, port count, location and orientation, thread/seat form, reservoir shape, mounting flange and level-switch connector; do not infer S13/S14 or ABS interchange from appearance. For the booster, match exact production/equipment identity, firewall stud pattern, shell diameter/depth and clearance, master mounting, pedal-side pushrod length and clevis, vacuum port, check valve and hose routing by physical comparison and qualified measurement because the catalog does not provide every dimension. Require written contents for master, reservoir, cap, grommets, level switch, booster, pushrod/clevis, check valve, hoses, brackets, nuts and hardware; anything unlisted is absent. Diagnose master leakage/bypass, booster/engine vacuum, check valve/hose, air, calipers and ABS hydraulics separately. Reject corrosion or bore pitting, fluid leaks, contaminated or swollen seals, cracked reservoirs, damaged ports/threads/seats, broken switches, bent or altered pushrods/clevises, dented or corroded booster shells, failed vacuum hold/check valve, water/fire/flood exposure and undocumented modification. Prefer a correct new or professionally remanufactured master; never accept unknown used hydraulic seals as ready to install. Follow current Nissan procedures and manufacturer instructions for bench bleeding with specified fresh fluid, installation, system bleeding, leak and pressure/vacuum checks, pedal reserve/return, ABS fault resolution and qualified low-speed then road acceptance before normal use.

Use a new or professionally remanufactured replacement only when the supplier maps the exact S13/S14, production, manual/automatic and ABS branch and provides the correct bore, port arrangement, reservoir/switch and mounting interfaces. Checked master observations included Sanyco M51504 for S13 non-ABS and Dynamic Friction 355-67087 for S14 ABS; checked 1996 booster choices included Centric 160.88605/160.88606 but require exact equipment confirmation. A used master or unknown used seals are not a ready-to-install option. A used booster/master package may be evaluated only from the actual stamped identity, donor/build, physical interfaces, complete inventory and safety condition; seller year-range wording cannot override the 07/1996 production split. Z32 upgrade, hydroboost, racing pedal-box and ABS-delete paths remain outside this factory guide.

US/LHD factory-vacuum-assisted 1989-1998 240SX only. Match VIN/build, S13/S14, production, manual/automatic, ABS, exact master identity/supplier/bore/ports/reservoir/switch and exact booster/check-valve/hose branch. Physically compare firewall studs, shell clearance, pushrod/clevis and hydraulic interfaces; no cross-generation or upgrade fit is inferred. Prefer a correct new/reman master, reject unknown used seals and damaged, leaking, corroded, contaminated, dented, modified, fire/flood or failed-vacuum parts, and require bench bleeding plus qualified final brake acceptance.
