Front brake help!

Postby Al3x2015 » Wed Dec 03, 2014 5:45 pm



I bought a 1982 gl1100 as a project bike non running. I finally got it running and almost ready to drive. I am doing the brakes now and when I bought the bike none if the calipers were attached. I tried to fit the front calipers on and it seems like they are too small for the rotors. I took the caliper bracket off and it seems like it is 1/8 inch too small for the rotor. It looks like the Tories are brand new because they have no wear marks. On the rotors they say 9mm, is this the correct thickness for this bike or could the calipers not match?

Hey Alex, Post some pictures of the rotors, calipers, and wheels. The bike is over 30 years old and it's hard to tell what someone has done. There's a bunch of guys on this forum that can answer that question and pictures always help.

Here is the caliper bracket up against the rotor. This is the only pic I have of it right now and I think the rotors on it are from an aspencade and I have an interstate.

The 1982 Aspencade has rotors unique to that year and model. You're going to have to either replace the rotor with one that matches the caliper, or get a 1982 Aspencade caliper.

Would it be cheaper to get the calipers or rotors? Also would all the bolt holes line up for the calipers? I would have to rebuild both calipers anyway because they are full if dried up brake fluid.

Yes you have Aspencade vented rotors. They were on the 82 and 83 Aspencade. The bolt holes are the same thus the wheels are the same on all three models of the 1100s(83 wheels can be used on your 82). The calipers are where the difference is in the openings for the rotors and the 83A have different right front calipers for the linked brakes with smaller pistons in the right caliper.
The Interstate and naked GL1100 had solid rotors that are thinner , and match the caliper dimensions you have.
Should you change the calipers or the rotors? Do the rotors. Save the next owners the problem of figuring out any changes you may do. You can get new rotors from EBC for the Interstate or find a good set or individual rotor as needed. The rotors have the minimum serviceable thickness stamped on them.

The brackets are different also on the Aspencade calipers, they have a groove for the rotor thickness.
Get the rotors.
Watch closely if you buy from fleebay, the sellers often list as fitting 80-83. There are many differences between 1980-81, 1982, and 1983 brake caliper parts, especially with the Aspencade, 1983 was a one year wonder, totally changed on the 1984 1200s. Can you cob it together, possibly. But...

The Interstate rotors will be the same on 1982 and 1983 Interstate and naked GL1100, the same holds true with the calipers of these.

Ok thankyou all! I have to go to a motorcycle junk yard soon to get some other things for my bike. When I am there I will see if I can get lucky and find a good set of 82 rotors (it really makes it easy that they put the year on the front badge!). Maybe if I do find good ones there the guy may be fine with trading rotors. If I can't find any I will just look around online for the rotors and try to sell these. I'm sure I can even make about $20 on these rotors since they are for a aspencade :)

82 & 83 gl1100 Interstate and naked GL1100 use the same rotors.
If I was back in SoCal I'd offer you an almost new right side rotor off a low mile naked 83 that's sitting in my storage but I'm in NH for the next year.

Yeah I'm going to try and sell the aspencade rotors on eBay for $100 together. Then get some $50 used rotors and turn them if they need it. Then use the rest of the money to get the rebuild kit for the 2 front calipers.
