been working on my gs1100ez lately. after draining the brake lines and adding new brake fluid. i cant seem to get the caliper into the forks leg. seem like it almost 4mm to wide... when i received my "project" they we not installed... anyone else have the same issue?
 
are you sure the pistons in the calipers are fully retracted?
have you had the front wheel off as well?
 
no i have the front wheel on. is it suppose to be off? yes they are push all the way in
 
no, i was just wondering if you did have the wheel off, it doesn't need to be.
dunno mate, are you sure you put the calipers back together correctly?
maybe post up some pics so we can have a look at whats going wrong here......

Here you go
 
it looks like you need to remove the mounting brackets from the calipers and clean up and lubricate the sliding pins. they seize up with lack of maintenance and the calipers dont slide back and forth as they should do.
you can see one of the bolts next to the bleed nipple in the first pic
 
OK will do this bike has been thru hell and back. I'm hoping to give it new lease on life. It won't be like this for long
 
Looks to me like the rotor is too close to the fork leg. Is this on the 82 1100? Those look like the early 78-79 rotor & I think the offset & thickness of the braking surface is different.
Hows the gap on the other side?

Also a possibilty of the spacers being wrong on the wheel, maybe there is a spacer that needs to go between the speedo drive & the fork leg on that model, I don't think so but it's worth a look....
 
I just took these from my 82 GS1100EZ, perhaps they'll help. Apologize for the dirt.










 
Yes its a 82 gs1100. Other side went in good..idk think i might pull the wheel off the gk and pit it on the ez and see if that helps at all. Plus the gk has slotted brakes

Click to expand...

This is a stock '82 GS1100EZ, it has slotted disks, yours should also, that might be your problem (wrong disks), don't know if the GK and EZ disks are interchangeable, I guess you'll find out.
 
Yep mine doest have.sotted brakes.. guess I know what I'm doing tonight:) .
 
Yea so I finally got around to switching the wheels and I ran into another problem.....the old non slotted rotor have a gap ( measured from.rim.to inside if rotor) 1 7/16" and the other rotor slotted also measured to same way was 1 1/2 "....having a larger rotor gap will cause more problems.

You can't measure that way I don't think... you have to measure from the bearing face.

Pretty easy to see if the rotors have the same offset, lay them down flat on a sheet of glass & see if they are the same height.
