Rear Master Cylinder Maintenance Kit NISSIN — Manufacturer reference: SRMK-004
Designed for the refurbishment of the rear brake master cylinder, this NISSIN kit gathers all the necessary components for a thorough overhaul. Intended for motocross riders and workshops, it allows for the replacement of internal wear parts (seals and sealing components) to restore proper functioning of the rear braking system.
Suitable for off-road motorcycles, this kit is particularly compatible with the SUZUKI RM-Z 250 (2025 & 2026) and RM-Z 450 (2018) models. Replacing worn seals and internal parts prevents leaks and abnormal play at the lever. For a safe intervention, follow the manufacturer's recommendations and carry out a proper brake fluid bleed, or entrust the task to a professional.
