Model-specific aftermarket replacement: This is an aftermarket bolt and washer pack for the CBR600RR brake-line connections listed above. It is not a genuine Honda component.
Materials: The replacement bolt is A2 (304) stainless steel. The two sealing washers are copper.
When should you replace a banjo bolt or its washers?
- When a brake-line joint is opened: Fit new sealing washers when reconnecting the joint, following Honda’s service instructions.
- If the bolt is damaged: Replace a corroded bolt or one with a damaged head or thread.
- If a joint leaks: Check the washers, hose fitting and mating surfaces; a new bolt alone may not resolve the cause.
Model-specific OEM replacements: Biker Bling selects the supplied replacement fasteners and fittings for the listed brake-hose banjo connection positions on the Honda CBR600RR 2003–2006, rather than supplying a generic assortment. The critical fitting dimensions match the original Honda fixings for those intended positions. These are aftermarket replacements, not genuine Honda-branded components.
Fitting the brake-line connection
Brake hydraulics are safety-critical. Position the brake-line fitting correctly and follow Honda’s workshop instructions for the specified fastener and tightening procedure. Do not guess a torque value. Keep brake fluid away from painted surfaces and friction components. If the line is opened, bleed the system as directed, then check for leaks and confirm firm brake operation before riding. Do not ride if the joint leaks or the brake feels abnormal.

Customer questions
Can this connect two stacked hose fittings?
No. Select a bolt and washer arrangement specifically confirmed for a double-banjo connection.
Where should I use the anti-seize compound?
Use it only where the relevant motorcycle or component instructions specify a suitable thread treatment. Inclusion of the pack is not an instruction to lubricate every fixing.
