Locating the rear wheel

  • Thread starter Thread starter StratJeff
  • Start date Start date
The rear caliper is fixed in position by the caliper mount and doesn't float on pins like front ones. The wheels position is thus determined by the spacers which appear to be correct (ignore my previous post about them being wrong). It looks like the caliper mount has an offset and is positioning the caliper too far to the left. Is it possible the caliper mount somehow got reversed?
 
The caliper mount only fits one way- it has a curve to it, and the curve needs to extend outwards from the axle in order to fit the caliper holes. Flipping it would put the caliper even closer to the wheel.
 
OK. I took some pictures of my GS1000. Note that the axle, wheel and all spacers except for the one between the caliper and the wheel are all the same part number as yours. Comparing your pics and mine it looks like the sprocket side spacer is correct but I question the spacer on the right between caliper mount and the wheel. Mine seems to sit recessed into the wheel much farther than yours. If that spacer on yours isn't correct the spacing for the caliper won't be correct. That spacer and the sprocket side spacer should fit right up against the inner bearing races on both sides. As mentioned the caliper position is fixed and the wheel position in relation to the caliper is determined by the spacers on the left side. This is all assuming the bearings are properly seated which they should be unless you've also had them out. Hope this helps.

Thanks for the pictures- unfortunately that's *exactly* how I have mine setup right now, and the rotor still drags.

It looks like I need some additional spacer inside the caliper V mount, to move the caliper out about 2mm. There's no other way I can see to adjust that.
 
This happened when I reinstalled the rear wheel on my 750. Can't remember if it was after doing tires or the 530 conversion. I'm racking my brain to remember how I fixed it, but I know I didn't add any spacers.

I'm gonna look thru some pics I took and see it that jogs my memory. If not, I hope looking at the actual bike this weekend will help me remember.
 
I had the same issue on my GS1000, turned out to be a sticking caliper piston, it would not return after being applied and caused the wheel to not want to turn freely.

I was changing wheels from one bike to another when it happened, but thought it was something I caused so took a while to figure it out.

Try it without brake pads and see if the rotor is running true in the center of the caliper.

yes remove the caliper and tighten wheel
bottom out pistons into caliper
re install then depres pedal till thhey seat
 
Maybe your wheel bearings and inter spacer are bad. I'd take everything apart and inspect. Something don't look right...

Yes, I second what Norm said because if things are assembled in the correct order it should fit properly (famous last words). The caliper is in a fixed position on the caliper mount and the wheel location is set by the spacers so there is no adjustment anywhere it simply should fit if all parts are assembled correctly. I appreciate your frustration with this. Maybe somebody with an 1100 can measure from the inside of the chain adjuster to the brake rotor or wheel, I can measure my 1000 as it has the same parts but an actual measurement from an 1100 would be more comforting.

Will this help or just confuse. If all ure spacers are the same u have a failed bearing somewhere. and since you didnt take my advice about checking those sprocket bolts seating correctly you HAVE NOT check the whole wheel.

I asked before, but you didn't specify- how would the sprocket bolts cause an issue, if the hub was never disassembled? I'm trying to understand why.

Excellent drawing Sharpy! I downloaded it for future reference 👍
 
Hey sharpy, the only thing that doesn't look right on your drawing is the left side spacer sits into the hub about half inch (most of the first lip of the spacer, which you can see in the picture above too)

I checked my right side clearances, and I'm around 37mm from inside the caliper mount to the adjustment bracket (your drawing says 36mm).

Thanks. Its a 80 GS1000ST rear set up, hence the added specs for a E wheel. FYI. Alloy GSX swingarms are 260 wide. Stay tuned :)

Left hand spacer disappears into a seal and the bearing is recessed.. Baring the 24mm one (brake bracket) all the rest are bearings and spacers. Ill double check about the 24mm measurement. Ok now im just showing off.......

Thought we rode bikes and you drove cars, And i would say the wheel in under the seat mostly.
