I have a holland radial break. As you know it is indexed so that the holes on the top are pointing straight up. I do not want to remove the break all the time to clean it because it will end up not indexing right after a while. I have no problem getting the ports clean, but I am having a hard time getting all the carbon off the crown. The crown is recessed back into the break a bit, making it hard to get all the carbon of the crown. I have tried Qtips with solvent on them,and carb cleaner, but they are just not getting it all. It isnt hurting anything, but I like to get everything cleaned off when I do a big clean. Im looking for any tips or tricks that you all use to clean your breaks. Thanks.
