Are there 2 different 1983 GL1100i Rear caliper types

Postby sperryunivac » Thu Jan 12, 2012 9:26 pm



With the cold weather approaching, I deceided it was a good time to rebuild the rear and front calipers. I received the caliper kits from PartsNMore and removed the rear caliper only to discover that the seals that I received were 25mm in O/D but the pistons in my caliper are 32mm O.D. I also had a look at the caliper seals that came with the front caliper kit and it seemed that there are seals for two different piston sizes. A quick check and I found out that left front caliper uses larger pistons then the right caliper pistons. No problem with the front kit I received but now I am wondering if there were two different calipers made for the '83 GL1100?
The parts manual for the 1983 GL1100 only shows one part number for each of the seals and pistons. I can see that a couple of the seals from the front caliper will fit the rear caliper.
Did anyone else come across this problem?

Well something is going on with PartsNMore but not what I need. They say that there is no rear caliper rebuild kit on the website for the 1983 GL1100i, but right there, I see the kit 29-0014 (just what I ordered). Has anyone else ordered that kit from them and received the correct seals?
Saber Cycle is staring to look really good now.

I think I have sorted out the mystery regarding the rear brake caliper. I have ordered many parts from PartsNMore in the past with no issues and this is the first instance of a problem that I have encountered. For anyone that is rebuilding a 1983 GL1100i rear caliper, do not order kit 29-0014 from PartsNmore as the seal are the wrong size. Even though the rebuild kit is listed for the rear caliper, the seals that come with the kit will fit the right front caliper only. And if you look at the web picture on the PartsNmore web site, you will see that the kit also comes with 6 rubber boots. So you will be paying for 3 extra boots not required. Correspondence with the vendor was extremely slow and the net result was to send the parts back. I did not get the feeling that the vendor is knowledgeable in the the Honda line ( and I am no expert either) but I was given the option to return the part for a refund. Given the fact that I had to pay to have the incorrect part shipped to me and to also pay to return it, I did not find it to be economically feasable to return the part. It would cost more for shipping then the parts are worth.
Doing further research, I found that I could get all the correct rear caliper seals from HondaPowerSports for less than $16. Problem solved.
WingAdmin, I have to say that this is the best web site that I have come across and it is very well organized, easy to navigate and has some of the greatest How-to-articles. Not only that, there are many great members on this site are very helpful too.
I hope that my caveat regarding the PartsNMore 1983 GL1100i rear caliper seals will be helpful to those considering doing the rebuild.

I ordered the 29-0014 for an 83 and I received 25 mm seals also.
I'm waiting for their response at this point.
No phone number to contact them, slow customer service and rude. It is very frustrating my experience so far.
They do not apologize for their mistakes just sit and wait for them.
Out of 10 items ordered I received 9, I asked when I will receive the missing part and no answer.
Price is right and quality of products received are nice.

I had the same issue, but I found some information on Saber Cyles.
http://www.saber-cycle.com/store/media/ ... d-Kits.pdf
It states that two different sources of calipers were used on the 83. Supply issues or something.

Well, I finally ordered the missing parts original from partzilla.com $6.95 Sh 3 days shipping in USA fast and reliable.
You will find the parts number for the front left caliper and if you need right will give you the part number.
Front left and rear are the same.

I own a 82 and an 83 gl1100a, what I have found is that the 82 has the same calipers on the front and a differant one on the rear. but the 83 has the same calipers on the rear and the left front (since these are linked it makes sence) and a differant one on the right front.
since I am not the original owner of these bikes it is possible that the prior owners screwed it all up but somehow everything works and so I wont be messing with it.... Until??

Nice posting here. It was great to have the part number kit NOT to order for the rear caliper of an 83 gl1100a. However, no one has posted the correct part number to order. Anyone???

I know that on the Aspencade (dressed bike) that the rear brake set up is different on the 83 compared to 82 which I have. This may explain the reason.

I stumbled across the same issue when I rebuild the calipers on my '83 last August. Here's what I found:

The 80-83 GL1100 parts manual (available on this site) has an error in the part numbers. For the 82, it shows part numbers for 30mm diameter pistons in the fronts and 25mm in the rear. It shows the same for the 83 - that's what is wrong.

The 82 had a conventional setup - independent front and rear systems. The 83 introduced the linked brake system where the front lever worked the front left caliper with 32mm pistons. The rear brake pedal worked the front right caliper with 25mm pistons as well as the rear caliper with 32mm. This size difference provided a stopping force bias towards the rear.

I also found the 84-87 GL1200 used the same linked arrangement as the 83. The correct Honda part numbers for the 83 can be found in the 84-87 parts manual - go figure.

Also, the master cylinders sizes are different too. Again, see the GL1200 manual.....

Btw, my Honda dealer had all the correct and updated info on this - so I sent back all the wrong parts I got thru others sources and bought every thing from my local dealer. This was a frustrating lesson to learn.
( Having learned it, I ordered all the parts for the front fork rebuild from the dealer also, as there were a few updated part numbers for obsoleted parts. )

When ordering from aftermarket sources they seem to be more interested in selling you stuff than delivering the correct stuff - so buyer beware!

One last thing. The calipers all have a number either cast in or stamped onto the front side of the caliper. This number in the size of the bores
machined in the casting and the piston diameters. If you have any question as to what size pistons or seals you need, well, the answer is right there.
(The master cylinders have these numbers also.)

Good luck with the brake job!
Bruce S.
Have a nice day! :)

Thanks Bruce!

I have been slowly figuring out the relation to the 1200's as well. Frustrating dealing with all this misinformation from these aftermarket parts sources. :evil:

Thanks again.

I ran into the same problem, my rear caliper is for a aspencade not a standard.

Look for an embossed number on your caliper. Mine had the number "32" on it (i.e. 32mm). Apparently things were so confusing at the factory, Honda had to label the calipers.
