GL1100 Rear Pad Spring

Post by GL1813 »



Hi everyone. New to the forum since I picked up a nice 82 Standard.
I need to replace a pad spring in my rear brake caliper on an 82 GL1100A Standard. I am not able to find an exact replacement anywhere. The part number for that particular piece does not correspond with the piece I have.
I’ve attached 3 pics. The pad spring that I have, the pad spring which the part number says it should be, and the diagram of my whole rear brake caliper from Honda. Problem is, the diagram shows the exact part that I need, but when you click on the part number, it shows an entirely different pad spring. I ordered it anyway from my local Honda dealership and it wasn’t the right one. I haven’t had any luck finding any info. Is anyone able to help me out???

Notice the Partzilla diagram in your image is showing the rear caliper for a 1982 GL1100 A(spencade) which has completely different brakes than non-Aspencade 1100's in the 1982 model year.

My parts diagram shows that the rear caliper spring part number for the 1982 GL1100 Aspencade is 43108-MA2-006, and for the Standard and Interstate is 43108-MA3-006.

The part you got, 45108-MA3-006 is the spring pad used for the FRONT brakes on 1982 and 1983 GL1100's.

Thanks for the info on the part number discrepancy. I am not seeing 43108-MA3-006 part come up on any searches. So that still puts me at an impass. I am trying to find a parts bike to get the whole caliper if necessary.

Interestingly, looking at Cyclemax's page, they list the spring for the rear of the 1982 GL1100 Standard as 45108-MA3-006:

https://partsfinder.onlinemicrofiche.co ... %20CALIPER

The parts catalog I looked up last night, lists these numbers:

Spring is item 5
Spring is item 5


Older parts catalog
Older parts catalog

I have a second parts catalog which is a little bit newer, and it lists it as 45108-MA3-006, same as the Cyclemax online catalog:

Spring is item 11
Spring is item 11


Newer parts catalog
Newer parts catalog

But clearly the spring you received looks nothing like that.

The newer catalog also lists 45108-MA3-006 as being for the front caliper.

So...where does that leave us? My suspicion: 43108-MA3-006 perhaps is an older spring specification, which was replaced with the 45108-MA3-006? That said, everywhere I look up 45108-MA3-006, it shows a picture that looks nothing like what the spring is supposed to look like:





Is it possible this is a redesign, and this oddly-shaped spring will in fact fit into the caliper? I can't say for sure, but it might be worth giving it a try.

Extremely helpful and I think you may be right. Ironically enough, I ordered it from my local dealership. When it came in I took the pad spring I had with me, but not the whole caliper like I should have. When we looked at the two springs together, neither one of us thought it would work. So I just returned it and the guy there and I have been looking at finding the right part ever since. I should have taken the caliper in to check the fit. Now that I discuss it with you, I’m going to check with the dealership and hope they still have that piece, or I’ll reorder it and hope it works out. I’ll let you know for reference either way. Thanks again for the insight
