    ...................hi you could try picking up 4 socket head cap screws , stainless steel ,,, they will do the job and they are not expensive regards oldgrumpy

      They are expensive, and they're grooved for O-rings.
      But they're stainless steel,
      polish them up with a wire buffer wheel.

        Do you need the bolts that attatch it to the mount arm or the carrier pins for the pads? If you need the carrier pins, just wire wheel them nice and replace the orings.

        Otherwise, take an existing bolt to the hardware. Be sure of the length because if it goes too far into the mount arm it will hit the rotor and that's not good. It can be just a tad shorter than the original ( 1mm or so ) but not longer unless you want to stack a bunch of washers on it.

          Hi thanks for replys, it is the mounting pins for the calipers I'm after I've been a few hardware stores and struggle to get same length bolt because they are metric fine thread with a shoulder on, which is for a tight fit into fork leg, also the carrier pins should I replace with new O-rings or can reuse the old ones I have not taking them off the carrier pin yet.

            Clean the carrier pins with the wire wheel. they don't need anything except new orings and some grease on the orings when you reinsert them.

            If the bolts your finding are too long, get a nut that fits them, put the nut on the bolts and cut to length. Wire brush the end where you cut the bolt off. Then remove the nut and the nut will fix the threads at the end of the bolt. Kind of like running a die up the bolt.

              You don't specifically "NEED" the flanged ones either. Regular machine bolt and a washer will do fine until you can source the factory one...if that's whats bothering you.

                Hi, thanks for info the bolts that I have are not flanged they have a shoulder on and the last 16mm Is threaded I didn't want to put a bolt on that's threadsed all the way up to head of bolt not sure wheather this will affect the purpose of bolts I don't want it to be dangerous, I still have old bolts so maybe I could either get them re-chromed or buy new ones.

                  Getting them rechromed is a bit of a lottery. Figures I've seen say a loss of around 8 - 10% stress yield strength after plating...

                  What i do is go to my fastener supply house with sample and ask for a high tensile bolt with the same length of unthreaded shank. It will of course be longer....that's what saws are for. I freehand grind the end to a nice lead in radius and de burr on a wire wheel.

                  The unthreaded shank is because you should not put a threaded shank through the alloy boss on the fork leg - it will carve it away...

                    I did not know chroming effected strenght, yes I have been trying to find bolts with metric fine thread and with the same length unthreaded shank but finding it hard to find them, only one I can find are m10 bolts with a long shank I was thinking of getting them and re-threading them as these have just metric standard thread.
