My Honda 750 F Supersport is equipped with dual front discs, but does not seem nearly as capable at stopping as is should be. The calipers were rebuilt by a local backyard mechanic who was a little primitive in his technique the few times I was present for work being done. He claims that because the brakes are single caliper devices that the brakes are working as they should be. The rear brake is a better grabber than the front, so I am deeply skeptical. I believe the master cylinder should be replaced (there were some shadows of fluid around the resevoir lid seam when I got the bike and the lid is slightly bowed out). If there is anything I can do without having to purchase new caliper kits, I would be thrilled. But if anyone thinks that is the right way to go, please let me know so I can bite the bullet now instead of when I'm closing in on a deer at 57 mph. Thanks much!!
