82 XJ1100 rear brake caliper drag

[HalfCentury]

Is there a picture of one that is that is correctly situated?

You know in that last pic it appears the torque plate is pinched in front of the axle bolt shoulder .It should ride on it .

I don"t have a photo share acct or I would .Best thing to do is loosen the axle bolt and make sure the shoulder goes through the torque plate and retighten the bolt . A quick search found this http://www.xs11.com/forum/showthread...ight=axle+bolt
Another supplied from your XS friends is here http://www.xs11.com/forum/showthread.php?t=27679

So you think possibly the axle shoulder is hitting the torque plate instead of the caliper bracket?

[SFerinTEXAS]

Just saying something looks out of whack. Only takes a few minutes to loosen the axle bolt and find out .Could be an optical illusion but seems possible .

On the other hand also seems unlikely due to the fact that the torque bracket also bolts to the caliper bracket and that should prevent it from doing what I first thought. Still looks out of whack.

[HalfCentury]

You are correct. It is pinched. The axle shoulder will NOT go inside of the torque plate.

The tires are Metzer Marathon with almost no wear. I suspect that when the tires were changed, the Gorilla in charge just hammered the axle home and called it good.

I removed the nut where the torque plate attaches to the caliper bracket. The torque plate wiggles freely in two degrees of freedom. No matter how the plate is wiggled, the axle shoulder will not go into the plate.

The third degree of freedom is hindered by the mount that attaches the torque plate to the swing arm. To gain access to this mount, it appears that the right shock absorber has to come off.

Comments and kibitzing are welcomed.

Now all you have todo is dremel the hole out to go over the axle shoulder .
make sure you have a good grommet on the swingarm peg . If not then go get a grommet kit from harbor frt . Match an id grommet to the swing arm peg.
cut it and place the cut forward . Push the bracket into the grommet and replace the axle shaft, A little pressure foreward is a plus. put the axle shaft in and BOB's Your uncle.

[HalfCentury]

Does the torque plate lift off of the grommet after the axle is removed?

How will I know where to apply the Dremel? Seems like possibly boring out the the hole a smidge may be an alternative to the dremel?

Hi Half Century,
I would not grind bore or beat on any of those original parts.
Sounds as though some one other than you did the work?
I suggest you have the manual handy and do the job over. Release all the tension and even remove the wheel if necessary. If you have all the correct parts and line them up the correct way (see manual) and tighten and torque to correct spec. it should resolve your issue.
If that does not work a PM to TRBIG who has lots of experience with XJ's will soon straighten you out

Good points. In the aftermarket manual for the XS1100 there is a passing reference on page 93 of the PDF. There is no mention of the torque plate riding on top of the axle shoulder. I can find no mention of the torque plate in the XJ1100 service manual.

I bought this bike from a guy who bought it in Wisconsin or Minnesota (I don't remember which) and rode it to Virginia Beach VA where I bought it from him. He rode it across country for grins and immediately sold it. It was a bucket list experience for him. He had no interest in owning the bike other than an extended joy ride.

On the other hand, I wanted one of these bikes ever since I had my XJ650 running and found it to be too small for serious freeway riding.

This summer I began evaluating the XJ1100 and riding it some. The only work I have done is to change all the fluids, rebuild the calipers and install a stainless brake line on the front right caliper and rebuild the front master cylinder. The front calipers were both seized.

I have concluded that there is no evidence that this particular torque plate actually fits over this particular axle shoulder. It is quite possible that the plate has been pinched all of its life. To be certain I will remove the axle and remove the torque plate to determine if the plate will go over the axle shoulder. It is possible that axle shoulder was deformed some time long ago during a tire change.

I found an inexpensive used torque plate on FleaBay. I will see if it fits over the axle before I remove the axle. I will perform a fit check with the axle in place on the bike. If the bracket hole needs widening, I can gently widen the hole until it fits over the axle perfectly and then pull the axle. The part appears to be stamped steel. There should be no danger to machining the hole if the hole does not fit properly over the axle shoulder. If there is disagreement over this point, I would be happy to hear that reason.

I am in no hurry and want to get everything right for the spring riding season.

The torque plate mounting hole inside diameter is 20mm as pictured.



The axle shoulder diameter is 26mm as pictured.


It appears to me that the torque plate of the XJ1100 is not designed to ride on top of the axle shoulder. Opinions are welcome.

The shoulder on the axle is supposed to clamp the torque plate/caliper bracket tightly when the axle nut is tightened.

[HalfCentury]

Thanks. Good to know. I do not see any mention of this in either of the service manuals I have. Is this just common knowledge or did I miss a reference in a manual?

I don't think it's specifically mentioned in the FSM, that's just the way it fits....

You might also check this: http://www.xs11.com/forum/showthread...ght=rotor+dish

While there's some adjustment available at the front calipers/rotors, there's virtually none on the LH/XJ rear brake unless you start installing non-factory shims. So if through some stroke of non-luck you have one of these oddball rotors, that would cause dragging issues. There's no easy way to tell by just looking, you'll have to pull the rotor off and measure it, although checking to see if the rotor is 'centered' in the caliper may give an indication.

If you do have one of these on the rear, you should be able to swap it with the same-side front rotor (which caliper can 'adjust') assuming that one is the 'regular' rotor....
