Sorry for the length of this post, I'm getting more confused with all the searching, rather than understanding these things better.
I've dismantled my caliper & been able to remove the piston, but still have some questions. I've done a fair bit of searching and am struggling to get to the point where I'm sure what to do.
Firstly, there's a shim that I'm missing. On the CMSNL website, it's part number 12. Sorry I couldn't link to a decent diagram, I've not been able to find one.
My system is missing that shim & it seems to be impossible to buy anywhere. I did read the last comment in this previous thread, which said it wasn't essential, but others said it was. Can I manage without it?
While searching for a manual with better pictures, I found this one. On page 92 of the PDF, it shows a diagram with the pads but no shim. The text, though, them says to grease the shim.
On the next page, it mentions bridge bolts and that they need to be replaced every time the caliper is removed. I can't find any diagram to tell me what they mean by a bridge bolt, though.
Next is the state of my parts. The dust seal & clip were missing completely, along with the shim.
As mentioned in my previous thread, I had to use an impact driver to remove the screw that holds one of the pads in place and I'd like to replace it. The bottom 5mm or so has no thread, as shown here:
I did try a normal M5 screw, but it wouldn't go all the way in, so I assume other end of this hole (below) is narrower than the screw thread.
The Yambits shim set for the XS650 (can't find one for XS400) shows a screw with a thread all the way along. Do I need to clean it up or re-tap it, or is it supposed to be like this?
Next, the bits from the same kit that are marked as "4. Retainer" on p92 of the manual I linked to. I've cleaned mine up, but when I put the pads back, they're quite tight and don't move freely on those retainers. Is that normal? See these 2 photos, where the pads don't slide down under their weight, but stay where they are:
The rubberboot for the bush & the bush seems fine. When putting them back, can I just push it through to a rough point, then bolt the bracket back to the caliper and it'll align itself? Or does it need to be a specific distance through?
Last question hopefully. There are a couple of photos of the piston below. There was a bit of corrosion that I've tried to clean up. Do you think it needs to be replaced, or is it OK?
