I ran into a slight problem when performing a rebuild on both of my front brake calipers for my 1983 GL1100 Interstate. I ordered two caliper rebuild kits (one for the left, and one for the right caliper). Both caliper rebuild kits were the same.

However, when I took off the calipers, the pistons are different sizes in both of the calipers. That means that my rebuild kits only fit one of the calipers. The caliper that fits with the rebuild kit is the right front caliper (the one that is linked with the rear brake). The left front caliper has pistons that are slightly larger than the right caliper, and therefore the rebuild kit seals are too small for these pistons.

I was wondering if this piston difference between the front left and right calipers is standard, or if my bike has a caliper from a different year on it. Second, how do I go about buying a rebuild kit for the left front caliper?

Yes, the different sizes are standard because one of the systemshas two calipers, the other a single. I take it you bought aftermarket?

I got all the OEM parts needed to rebuild both my front calipers from Western Honda for less than 35 bucks. Including tax!

When ordering caliper rebuild kits, the '83 GL1100 front kits are like the GL1200 kits. Many sellers do not know this and supply the '82 and '83 kits as the same.

83 was a transitional year apparently. I found the wheel speed sensor on my Interstate is actually the same part as on a 1200. Let us know how your rebuild goes, I need to do something like that myself.

I had ordered my rebuild kit from Saber Cycle, and their refund policy states that I cannot return the parts I ordered if they are incorrect parts. However, their site lists my 1983 GL1100 as having only one size set for the front brake caliper rebuild kit :(

Here is the response I got back from Saber Cycle:

"The front brake calipers on the GL1100 are the same - unlike the GL1200 that has two different ones. Somebody has obviously changed one of your calipers for whatever reason. You are going to have to figure out what you have or go to Honda and buy the seals you need."

Plus, I have the Honda service manual, and it only shows one size also. When I look at the diagrams on the Bike Bandit website, it also shows only one size brake caliper for the front brakes. (The calipers look about the same size, but the piston sizes is what is different.

Does anyone even know if GL1200 front calipers will fit on a GL1100? or more specifically, a 1983 GL1100?

Would anyone suggest that I purchase a caliper rebuild kit for the left front caliper from the GL1200 kit?

I also purchased a speedo cable from Saber Cycle that was listed on their website as being for the '83 GL1100. I haven't installed it yet, but it looks the same. I'll let you know if I have any difficulties with it when I have a chance to install it!

Maybe you'll learn your lesson and quit buying from them A*******. And people wonder why many of us don't. True, there are Saber lovers here, but their policies and attitude SUCK!

Been like that forever, and it's NOT going to change despite what gets posted here....

Sorry for being harsh, but do some searches on decent vendors.....

Thanks for the heads-up. I am a new Gold Wing owner, and this is my first time (any maybe last time) buying from them. Do you have any recommendations for ordering online?

Do you do ebay? There is Georgefix on ebay, plus Partsnmore in Canada. There's lots more vendors here and there, but you got a taste of their customer service first hand.

No one changed your calipers, they just barely know what they are selling. And plus, they are NEVER wrong...

http://www.partsnmore.com

(both appear to be out of stock at the moment...)

Others will chime in here with other vendors, just check later...

The difference in calipers has everything to with the '83 having a linked braking system, and not single versus dual piston calipers. In the 4 years of GL1100's there are 3 VERY different braking systems.

The '83 is close to an '82 as far as calipers, but on the '82 they are the same size pistons on both left and right, where the '83 has 2 different sizes like the GL1200 has.

I suppose I will order a Caliper Rebuild Kit for a GL1200 Left Front Caliper, and hope that it fits.

Then, hopefully I can recoup a couple of bucks off of the spare rebuild kit that I have by selling it on eBay (unless anyone here wants it).

That's really strange. I've checked three different sites and each showed two pistons, but only one seal and dust boot. As all have said the calipers are very similar but each has different diameter pistons seals and dust boots. It seems to me that the left side and ride side had MA7 and MB7. I've tried to look up theseby part number but the MB comes up as invalid. I've gotta go now. Good Luck!

I buy mostly OEM and always from www.westernhonda.com

They really are the best from my experience. I've never had any other dealer treat me so much like a valued customer.

Ok, so out of all fairness, I should update this forum to reflect that Saber Cycle did offer to refund me for the caliper rebuild kit that I couldn't use. I sent the part back, and they refunded my credit card.

On another note, I still haven't found a proper rebuild kit for my left front brake (the one that has the larger pistons). I am hoping to drop by the Honda shop sometime this week. I'll post updates as they become available. Thank you all!

So the one they had was for the smaller piston size? I believe the left side is 32 mm which the same as the 82 calipers if I remember right, will have to double check that though. Good memory, just short.

Your left front caliper will use the same kit as the rear of your bike . ITs the right front that has the smaller pistons .

I went to my local Honda dealer, and asked the parts department about the difference in caliper pistons between the left and right front calipers. Their computer showed two different sets of seals and pistons, so I ordered the seals for the left caliper that I needed, and then I bought two new pistons for the right front caliper, and two new pistons for the left front caliper.

On reassembling the calipers, I did have a little trouble getting the new pistons into the caliper. I thought this was good, since it probably means that it created a good seal. I just used the brake fluid to lubricate the caliper pistons when inserting the pistons into the caliper. That may be why it was difficult to get back in.

I did notice that my brake like was very slowly leaking from the banjo bolt on the front left caliper. I put it back on properly (with one washer above, and one washer below the brake line) and tightened the banjo bolt very tight. The leak from the banjo bolt is very, very slow. If I leave my bike sitting overnight, there is only one drop of brake fluid on the floor the next day.

Also, my front brake handle is a little spongy and soft, which most likely means that I have air in there somewhere. I did what I read on another forum, which was to compress the brake handle overnight, and then bleed again in the morning. I was surprised at how much air came out the next morning! I did this with both the front handle, and the pedal brake.

I'm not too worried about the sponginess, as this is exactly how the brake felt when I bought the bike about two months ago. Plus, it makes stopping a little smoother, but I can still stop on a dime if I pull it hard enough. But, when I get some more time, and maybe an extra hand, I'll try to get more air out of it.

When bleeding the pedal brake, I only had to bleed the right front brake. It didn't seem like I had to bleed the rear brake (even though on my 1983, the front and rear brakes are linked). However, my brake pedal was sticking, and not returning to the resting position. So again, I read another forum on here where someone said to use WD-40 and work the pedal back and forth to get the gunk out. I removed the pin from the rear brake and the little spring for the brake light to allow more leverage when working the pedal up and down. It only took about 5 minutes of spraying WD-40 and working the pedal up and down for it to free up. Now it works as good as new!

As OnaWingandaPrayer stated "Your left front caliper will use the same kit as the rear of your bike . ITs the right front that has the smaller pistons." I looked at my rear caliper pistons and they look like they could be the same size as the front left calipers, but I didn't take my rear caliper off, so I don't know for certain, but it would be a pretty good bet that they are the same size. I wouldn't have even thought to think of this, so thank you OnaWingandaPrayer!

As for the speedometer cable replacement, the one I ordered from Saber Cycle fit like a glove. The speedo cable fit really good, and I haven't had any problems with it (I've been using it for a week now). I bought some white lithium grease that came in a spray can to lubricate the speedo cable.

Now, my tachometer cable is whining, and I can't figure out how to get it off from the engine to lubricate it, but I'll post this problem on another forum, so if you have a solution for this, or want to follow that forum, just do a search for it (1983 GL1100 tachometer cable).

Thank you everyone for helping me through this process. If anyone is going to be performing this work and needs some help, feel free to ask!

you can get new crush washers for your banjo fittings from most motorcycle shops, honda or even harley. Just ask for 10mm brake banjo crush washers. They are cheap and that might stop the leak. JB
