      I’ve had a few people ask so I just wanted to bump this thread to say that I do have sets of brackets on my shelf currently.

        Just a quick post of thanks to salty_monk and everyone for their tips on this thread. Installed a set on my 79 GS550, with calipers from a 88 ZX10, cafe racer build and they are a great modification. After about 6 months of work the engine went in last weekend. Wiring and brake lines left to install and should be back on the road soon.

          Welcome to the site, JT.
          The discs look new. Are they from a ZX10 as well?
          How about starting a thread with your build info in the "Projects" section.

            Thanks!

            The discs are new EBC discs (EBC MD1014X) and then just enlarged the holes to 8mm. I liked the look of the gold discs against the black wheels which I have also mirrored with the rear shocks. I've added the master cylinder off a 2010 Kawasaki ER6 so should be a pretty solid braking setup.

            I'm keeping all the images stored and will provide a full build thread once I've got nearer completion, hopefully early next year.

                Hi Salty Monk, I have borrowed your ideas of the Honda disks and Concours calipers to uprate the front end of my GS1100GK. As you will know the GK has fatter forks and wider trees than everything else. I didnt have to shim the disks at the hub, and using the original Concours brackets with some extensions welded on (certified welder, crack tested) located the calipers spot on over the disks. Used the Concours span adjustable m/c as well. Picture over at the "what did you wrench on today" thread. Thanks for the inspiration.

                  Great, glad it worked out. A couple of people have welded brackets the way you have, seems like it should work ok and has for them as far as I know.

                  I’d definitely want a good welder as you did, would be good to know the material used originally, I was a bit worried it would “let down” the bracket and make it flex but I think it’s thick enough that you’d be ok even if it did.

                    These seem like a good option for brand new master cylinders from a trusted source. Look vintage enough for even the older Suzuki’s and are the correct bore size. $61.

                    I’d be interested in feedback if anyone tried one out.

                      Just wanted to bump the thread to let members know that I do currently have brackets. Due to some drop off in demand over the last year or two this latest batch will likely be the last time I run these.

                        I may be interested in picking up some brackets. First, I'm trying to figure out if the '83 GS550ES calipers will directly bolt on to my '81 GS750E forks. I want to upgrade to opposing piston calipers rather than the sliding/floating calipers.

                        Question:
                        Can I install other calipers with your brackets? Specifically, the Yamaha four pot blue dot calipers? FJ1100 with blue dots.

                          Another question:
                          Have you considered making and selling radial conversion brackets? I'd love to put on the Yamaha six pot radial calipers? RC51 with silver dots.

                            I'd love to too! Those FJ guys have a lot more room to work with between the fork legs. We're stuck with twinpot sliding pin calipers I'm afraid, opposed pistons just won't safely fit on anything other than an 1150 using stock forks & wheel.

                              Are you be able to custom any brackets for any calipers or ?

                              Comment


                                I responded in your other thread. It's a specific bracket set for a particular choice of calipers & rotors on stock forks & using stock wheels. Lots of info earlier in the thread if you read through.
