RCB E-Series Steel Braided Brake Hose (1300mm) is a high-performance hydraulic upgrade engineered to replace soft, expandable factory rubber brake lines.
Part of RCB’s highly reliable E-Series, this extra-long 1300mm (130cm) universal hose is optimized for long hydraulic runs. It is primarily sized for rear brake systems on maxi-scooters (where the engine and caliper sit far back on the swingarm) or front brake systems on custom cruisers, choppers, and adventure bikes with ultra-tall handlebar risers or ape hangers.
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 balloon and expand under high pressure—especially across long 1.3-meter runs—this braided shield eliminates volumetric expansion, delivering maximum hydraulic force directly to the caliper pistons.
-
Crisp, Immediate Braking Response: Long rubber lines are notorious for absorbing hydraulic pressure, creating a very “mushy” feeling. By preventing line expansion, this hose transforms a spongy lever or pedal feel into a firm, highly communicative, and immediate stopping response with significantly shorter stroke travel.
-
Anti-Friction Protective PVC Jacket: Wrapped in a smooth, clear or tinted PVC outer sleeve. This protective layer prevents the abrasive steel braiding from scratching your motorcycle’s body panels, chassis frame, or painted swingarm during suspension compression.
-
Premium Corrosion-Resistant Banjos: Equipped with robust, heavy-duty banjo fittings at both ends, engineered to withstand high torque loads and provide a permanent leak-free seal under extreme racing 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, Vespa, etc.).

Installation Guidelines
-
Verify Length Through Full Travel: Before tightening, route the 1300mm hose completely along the chassis to ensure it fits comfortably. Crucial Safety Step: Put the bike on a paddock stand to completely extend the suspension and turn the handlebars fully from lock to lock. The hose must not pull taut, bind, or pinch against any steering stops or moving suspension elements.
-
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 a long 1300mm brake line introduces a massive volume 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.
