About This Product
Rebuilding your rear master cylinder is a critical maintenance task for keeping your Harley's stopping power consistent. This complete repair kit from Zodiac includes all the internal components needed for a full overhaul of your OEM or stock replacement unit. It is designed to fit a wide range of FX, Sportster, and Touring models, serving as a direct replacement for OEM part 42374-77B. Whether you are running DOT 3, 4, or 5 brake fluid, these internals will handle the job, though you must ensure you do not mix fluid types during the bleed. This kit is suitable for both ABS and non-ABS master cylinders, provided they feature the standard remote or integrated reservoir as specified for these classic Harley-Davidson setups.
