Overhauling the front brake master-cylinder assembly? If you replace with as many new parts that can be afforded, the results in performance, safety and not forgetting aesthetics can only offer positive results.
This component, and many of those listed below might merit your attention:
The more new correct spec parts used the better the overall results.

Please be aware that this component will have many applications for other models from the Honda range.
