Shimano SM-BH59-JK-SS Hose Kit

Product Overview

The Shimano SM-BH59-JK-SS is a complete hydraulic brake hose replacement kit designed for Shimano hydraulic disc brake systems. This kit includes a 1.70m pre-assembled hose with straight connections and all necessary fittings for installation or repair. It provides everything needed to replace worn, damaged, or kinked hoses while maintaining system integrity and performance.

Key Features

• 1.70m pre-assembled hose – Standard length accommodates most frame sizes and routing configurations; can be cut to custom length if needed
• Straight hose connections – Direct fitting geometry (versus banjo) enables clean integration with lever and caliper without additional adapters
• Complete fastener package – Includes 2 olives, 2 connectors, 2 joints, and 2 tips; provides all components necessary for secure, leak-free installation
• Shimano-specific design – Engineering and materials optimized for compatibility with Shimano mineral oil hydraulic systems; ensures reliable pressure transmission
• Reinforced hose construction – Built to withstand hydraulic system pressures without expanding or degrading; maintains consistent braking feel and modulation
• Easy installation – Straight fitting design simplifies hose routing and connection compared to banjo fittings; requires basic mechanical skill
• Universal Shimano compatibility – Works with most Shimano hydraulic brake systems using SM-BH59 hose specifications

Compatibility and Ideal Use Cases

• Compatible systems: Shimano hydraulic disc brakes using SM-BH59 hose specification (primarily entry-level and mid-range systems like Deore, SLX, XT)
• Brake models: Shimano BR-M200, BR-M4050, BR-M6000, BR-M6100, and other systems specified with SM-BH59 hoses
• Frame routing: Straight connections suitable for external and frame-integrated hose routing; can be routed through internal frame channels
• Hose length: 1.70m provides adequate reach for most frame sizes; excess length can be trimmed with sharp knife or hose cutter
• Best for: Brake system maintenance, hose replacement due to wear or damage, custom brake line routing, and system rebuilds
• Ideal use cases: Damaged or kinked hose replacement, internal frame hose passage, and complete brake system reassembly
• Installation requirement: Proper connector torque critical for leak prevention; follow Shimano torque specifications (typically 3-4 Nm for hose joints)
• Maintenance: Replace olives and gaskets during hose installation; damaged olives cause leaks even with correct torque
• System preparation: Bleeding necessary after hose installation using Shimano mineral oil and proper bleeding kit
• Field repair: Complete kit eliminates need to source individual connector components; enables quick hose replacement in field or workshop
• Critical note: Shimano Mineral Oil seals are specific to Shimano fluid—substituting other brand mineral oils will destroy internal seals and void warranty; use only genuine Shimano Mineral Oil in systems with this hose; confirm oil type before installation or any subsequent maintenance; do not mix Shimano hoses with non-Shimano brake systems
