Hydraulic brake and clutch systems are the most critical safety components in any motor vehicle. When maintaining, repairing, or restoring Japanese automotive and commercial vehicles, aftermarket professionals and fleet mechanics consistently rely on Seiken Chemical Industry Co., Ltd. As an original equipment manufacturer (OEM) and premier aftermarket supplier, Seiken produces high-grade hydraulic cylinders, seal kits, and rubber components.
Understanding the catalogue begins with understanding the brand behind it. Seiken is not just a name; it is a brand built on a rich heritage of Japanese engineering excellence. Its story is deeply intertwined with Meiji Sangyo, a company that established a dedicated Brake Laboratory in 1937. A year later, in 1938, they achieved a significant milestone by successfully domesticating the production of brake rubber cups and brake fluid in Japan.
Seiken’s modern catalogue (available in PDF and digital interactive formats) includes two unique features:
Seiken specializes in high-durability rubber components that resist degradation from brake fluid, a common cause of failure in lower-quality parts.
The catalog covers a vast range of Asian, European, and American vehicle applications. 2. Seiken Brake System Components Catalogue seiken hydraulic brake amp- clutch parts catalogue
While veteran parts counters still appreciate the reliability of a physical Seiken paper catalogue, digital e-catalogues offer distinct operational advantages. Features of Electronic Seiken Catalogues
(e.g., NPR71, LN106, FK617). This is highly critical for Japanese Domestic Market (JDM) vehicles.
Includes pistons, seals, and slide pins to maintain proper caliper function, preventing seizing and improving brake longevity.

Whether using the Seiken digital e-catalogue portal or a printed catalog matrix, follow this systematic approach to isolate the exact part number.
In the world of heavy-duty machinery, automotive repair, and industrial equipment, the difference between a safe stop and a catastrophic failure often comes down to a single component: a hydraulic seal, a master cylinder piston, or a clutch actuator. When professionals demand reliability, one name consistently rises to the top—. However, even the best components are useless if you cannot find the correct part number. This is where the Seiken Hydraulic Brake & Clutch Parts Catalogue becomes an indispensable tool.
Seiken is unique for developing both the physical metal components and the chemicals required for hydraulic systems, ensuring perfect compatibility.
You have a Nabco brake master with the number "44100-1260" on it. A year later, in 1938, they achieved a
Seiken does not always maintain a public-facing global parts catalog. Instead, look in these places:
Selecting the correct part number from the Seiken catalogue is only half the battle. Preserving the longevity of Seiken hydraulic components requires strict adherence to professional installation protocols. Fluid Compatibility

The catalogue lists the cylinder by the axle type (front or rear), the number of wheel cylinders per wheel (single or dual leading shoe), and the bore size. A typical entry for a Mitsubishi Fuso Canter might read: "Wheel Cylinder – Front – 1-1/8” Bore – Left Hand – S-WC-205."
