There are a few great replacement front brake kits around that are all bolt on with mounting brackets and all, it all depends on how deep your pockets are and your use, when my stock brake system let me down in 2 minor accidents the last one I suffered a fractured left arm and broken left thumb was time to replace the old system completely 10+ years ago while recovering, I ended up going for a full Grimica system from RGM, 12" semi floating disc, Grimica caliper with mounting plate, SS brake line and Grimica MC with a longer leverage leaver, this whole set up cost was just a tad over $500 at the time, this has changed my whole front brake to a fully working system and one finger operation if you want to use one finger, for my light hotrod Norton its great when you need to brake hard in an emergency, I am not a heavy user of brakes but its great to know the bike will stop when needed, 10+ years now on the Norton and still working as good as the day they been installed.
As I say there are many great front brake kits around from Brembo, to Madass upgrade kit and more, I went with the Grimca system as it was the right price for me at the time with fast delivery to my front door, Grimca brakes have been around for a very long time including racing, but its up too you in what you want, I am very happy with my set up and how good they work for the money I spent.
