I'm rebuilding then brakes on my '82 GS 550M (Z) and I'm a little perplexed by the axle bolts. They have a couple of grooves in them, which look like they should have o-rings - see no. 8 in this fiche:
Mine didn't have any (but were also missing the seal between caliper halves for the rear, so wouldn't assume it's correct) but o-rings are also neither in parts fiches nor in any rebuild kits I've seen.
I looked through the guides on BikeCliff's (excellent, thanks for that!) site, and the one for earlier models shows similar bolts with o-rings on them.

If these later model calipers don't use o-rings on the bolts, why do they have the grooves?
...and one more question, would anyone happen to know the dimensions of the seal (flat o-ring) between the rear calipers? PN 6910734200
no. 5 in this fiche: https://www.cmsnl.com/suzuki-gs550m-...1.html#results
It was completely missing from mine, and that little bugger will cost me $45 shipped... unless I can find a "generic" one with the right dimensions and material (EPDM I assume)
