Product Description
Restore the sharp, responsive feel of your braking system with the Genuine Royal Enfield Master Cylinder Minor Kit. This OEM internal repair set (Part No: KAB00028/A) is the factory-spec solution for overhauling the front brake master cylinder on the J-Series 350cc platform.
The KAB00028/A kit includes the high-precision piston assembly, return spring, and specialized secondary seals required to maintain hydraulic pressure. Over time, brake fluid can degrade internal rubber seals, leading to a “spongy” lever feel, fluid weeping, or a gradual loss of braking power. Instead of replacing the entire expensive master cylinder assembly, this “minor kit” allows you to refresh the internal components to factory standards. Made from chemical-resistant elastomers and lightweight alloys, these parts are engineered to withstand the high-pressure environment of the modern Royal Enfield ABS braking system.
Key Features:
-
OEM Hydraulic Performance: Restores the exact lever pressure and “bite” as per original factory settings.
-
High-Grade Seals: Features EPDM rubber seals designed to resist swelling and degradation from DOT 4 brake fluid.
-
Fatigue-Resistant Spring: Includes a high-tensile return spring to ensure the brake lever snaps back to position instantly.
-
Safety Critical Restoration: Eliminates brake fade and fluid leaks caused by worn-out internal pistons.
-
Precision Fit: Specifically sized for the newer J-Series master cylinders found on the 350cc lineup.
