RCB E-Series Steel Braided Brake Hose 550mm is a high-performance hydraulic upgrade engineered to replace soft, expandable factory rubber brake lines.
Part of RCB’s highly reliable E-Series, this 550mm (55cm) universal hose is specifically sized for shorter hydraulic runs, making it an ideal choice for rear brake systems on most sport and street motorcycles, or the front brake systems of smaller scooters and underbone bikes.
Key Features
Zero-Expansion Stainless Steel Braiding: Constructed with a high-density, woven stainless steel outer mesh that encases a heavy-duty Teflon (PTFE) inner core tube. Unlike stock rubber hoses that swell and expand under hard braking, this braided shield eliminates volumetric expansion—delivering maximum hydraulic pressure directly to the caliper pistons.
Eliminates Spongy Lever Feel: By preventing line expansion, it transforms a “mushy” or spongy lever/pedal response into a firm, highly communicative, and immediate braking feel with significantly shorter lever travel.
Anti-Friction Outer Protective Jacket: Wrapped in a smooth, clear or tinted PVC outer sleeve. This protective layer prevents the abrasive steel braiding from scratching your motorcycle’s swingarm, frame, or painted plastics during suspension movement.
Premium Corrosion-Resistant Banjos: Equipped with robust, heavy-duty alloy banjo fittings at both ends. These fittings are engineered to withstand high torque loads and provide a leak-free seal under extreme braking pressures.
True Universal Application: Designed with standard 10mm ($M10$) banjo eyelets at common entry angles, allowing it to easily bolt onto OEM or aftermarket master cylinders and brake calipers across almost all motorcycle brands (Yamaha, Honda, Suzuki, Kawasaki, etc.).

Installation Guidelines
Verify Length and Clearance: Before installation, route a flexible measuring tape along your current brake line path from the master cylinder to the caliper to ensure 550mm provides enough length. Always allow for full suspension extension and steering sweep without pulling the hose tight.
Always Replace Crush Washers: The kit relies on copper or aluminum crush washers to form a hydraulic seal. Never reuse old, compressed factory washers; always install fresh washers on both sides of the banjo fitting to prevent dangerous fluid leaks.
Torque Safely: Tighten the banjo bolts to your motorcycle manufacturer’s recommended torque specifications (typically between 20 to 25 Nm). Over-tightening can strip the threads inside aluminum calipers or snap the hollow banjo bolt.
Complete System Bleed: Disconnecting the brake lines introduces massive amounts of air into the hydraulic system. Refill your reservoir with fresh DOT 4 fluid and perform a thorough brake bleeding process until all trapped air bubbles are completely purged and the lever/pedal feels rock-solid.
