I own a 1977 CB750F F2. This particular model is apparently different than other F2's of the same era. I ordered both front and rear brake line sets. I received them and found that the front brake set was OK except for the orientation of the banjos. (I did not know that they were adjustable!) I contacted BrakeCrafters via email and got a reply the next day. I was sent a video on how to adjust the banjos, it worked like a charm. The rear brake line was 2 inches too long, I let them know and suggested I send my old brake line for comparison. They accepted my offer and are making a duplicate of my old brake line. That my friends is exemplary customer service. I have several other motorcycles that will need brake parts and BrakeCrafters will get all that business!
