Rich.E Posted October 10, 2023 Share Posted October 10, 2023 I'm fitting my big brake upgrade and found that I need to use shims on the LH side between the upright and caliper to centre the caliper on the disk, I suspect the disk is too far inboard? and that the bearing spacer shim maybe wrong? there is one fitted but I don't know if it's correct or do I need two?it works just fine, but bothers me that it's not the same both sides Thanks Link to comment Share on other sites More sharing options...
7 wonders of the world Posted October 12, 2023 Share Posted October 12, 2023 Shims are for that purpose to correct slight variations in manufacturers tolerances in hubs steering arms calipers etc.The most important thing is to get the caliper as central over and parallel to the disc as possible.You can buy shims down to 0.1mm online to if needed Link to comment Share on other sites More sharing options...
