Caliper mount touching disc
Hi there,
I have begun a project to rebuild my rear brakes on a 1980 GL1100 Standard.
I have removed the calipers, I notice that the mount is touching the disc on the outer edge (away from bike).
How do I adjust that?
Thanks,
Dan.

Re: Caliper mount touching disc
There could be a spacer or washer incorrectly installed or backwards in place.
Check a Honda parts fiche for all the pieces that are required back there and see if there is something missing or backwards in the installation.

Re: Caliper mount touching disc
I check the parts ficke out and state of the axle -- it seems fine. Any other thoughts?
Thanks,
Dan.

Re: Caliper mount touching disc
Was it rubbing the disc prior to removing the caliper? My experience is normally a washer or spacer is off when that happens. How about a better picture of the whole assembly with the axle and spacers/washers visible?

Re: Caliper mount touching disc
I do not remember it rubbing, however my brakes used stick -- therefore the rebuild.
Do do these help?

Re: Caliper mount touching disc
The outer section looks correct on your installation. If you check the parts fiche on the inside part of the lower rear caliper bracket where the axle goes through closest to the wheel, there is a washer/spacer shown on the rear brake parts fiche. If you are missing that washer/spacer then that is your problem with the correct alignment.

Re: Caliper mount touching disc
Is this what you are referring to #1?
Guess I will need to disassemble the wheel then.
Thanks,
Dan.

Re: Caliper mount touching disc
That's it. If you pull the axle it will fall out if it is actually in place, if not there then that is why your caliper bracket is offset from the correct position.

Re: Caliper mount touching disc
Thanks much. Went ahead and ordered a NOS so that I have it handy when I do pull the axle, just in case

Re: Caliper mount touching disc
In the picture I think I'm seeing the washer mounted on the wrong side of the caliper bracket. Hard to tell with the accumulated crud.

Re: Caliper mount touching disc
Yes it is confusing, yet the spacer Track is referring to is the one that fits into the rear wheel seal I think and then the thin washer and then the inside of the caliper bracket. The strange thing is the outer spacer that is shown in Dan's picture of the axle is not shown, at least where I can find it on a parts fiche.
I have a 1981 GL1100 Standard and it shares the same parts as Dan's 1980 GL1100 Standard on the rear section. So he has the correct set up on the outside and if he was missing that spacer #3 on the inside it would be a bigger issue.
IMO I feel the thin washer is missing, which would shift the caliper bracket a MM or so to the outside and correct the rubbing on the rotor.
Could be wrong.

Re: Caliper mount touching disc
Ok now I am confused, as I pulled up some pictures of the before disassembly of my 1981 GL1100 as I tore it down a few years ago. You can clearly see the outer spacer on the outside of the axle and caliper bracket and the inner #3 rear wheel spacer, yet I can't see or tell if the washer is in place, yet my rear caliper does not rub.

Re: Caliper mount touching disc
Flyin900... your pictures show the correct setup for the axle. Large flat washer outside, which rests on the shoulder of the axle, caliper mounting bracket, then inner flanged spacer. One thing I've discovered... there are two different flanged spacers; one thicker than the other which changes the offset of the caliper. Possibly different from 80-81's and the '82? I've got parts from both years leading around and could have mixed them...

Re: Caliper mount touching disc
Track I don’t think that is correct on that outer spacer, it is designed like the #3 spacer in its look with the larger diameter bulb of the axle that enters into its front opening and seats inside there.
The washer is the question, as I don’t see it in my picture, yet if placed on the inside of the bracket it would shift the caliper bracket out enough the stop the issue.
If there are different sized flanged spacers that is possible, as I have only worked with what I have on each bike.
