HOPE BORE CAP TOOL MM6 SMALL
Maintain your premium stopping power without damaging your hardware. The Hope Bore Cap Tool MM6 Small is a vital addition to any home mechanic's or professional bike workshop's toolkit. Specifically engineered for Hope's iconic hydraulic disc brake calipers, this tool matches the precise internal pin configurations of the caliper's small-format bore caps. It provides a non-slip interface that enables you to safely extract or torque down components during deep cleans, seal replacements, or custom piston upgrades.
Machined with legendary precision by Hope Technology in Barnoldswick, UK, this tool eliminates the risk of scratching, gouging, or stripping your anodised caliper parts—a common disaster when trying to use makeshift pliers or standard tools. Featuring a robust, integrated hex drive interface on the back, it allows you to connect a standard spanner or socket wrench easily, giving you maximum leverage and controlled force when breaking loose factory-sealed or stubborn, corroded bore caps.

✅ Why This Product IS For You
Dedicated Bike Builders: Perfect if you own classic Hope Mono M4 or M6 brakes and want to perform your own caliper overhauls, seal changes, or custom piston rebuilds.
Professional Workshops: Ideal for bike mechanics who require the correct, factory-approved tool to service premium customer brakes without scratching the anodised finish.
Restoration Projects: Great if you are reviving older, high-end mountain bike braking systems and need to break loose stubborn, long-seated factory thread lock safely.
❌ Why This Product May NOT Be For You
Modern V4 or E4 Owners: This tool is designed for older Mono-series calipers; it will not fit modern Hope Tech 3 or Tech 4 V4/E4 models, which require a different multi-pin tool.
No External Wrench: This tool consists solely of the machined socket piece; it cannot be operated standalone and requires a separate spanner or socket drive to turn it.
BFC PRO TIP
Hope factory bore caps are installed using a strong thread-locking compound from the factory, which can make them notoriously stubborn to break loose initially. Before you apply hard wrench leverage, use a heat gun or a hair dryer on a medium setting to gently warm the metal caliper body for 30 to 45 seconds. This softens the internal thread lock adhesive, allowing the tool to smoothly break the seal without slipping or damaging the delicate pins!
