If you have to perform maintenance tasks for your Honda CBR400RR then it will always be a good idea to have a Workshop Manual to keep just for a reference if you want to know the way to strip off a specific part such as the Brake Discs and fit it again in the correct manner.
Honda CBR400RR Workshop Manuals can offer you targeted diagnostic guides with regards to your car or truck so if something is broken it can help you understand what the situation is and the best way to repair it. Then you are able to analyse if you can do this yourself or if ever the job is simply too big it is possible to make a booking for your CBR400RR into a local repair garage.
