rear brake dragging with new wheel
I just changed out the cast rear wheel on my 1990 evo softail to a ultima 40 spoke rear....now the rear brake is dragging....just want to make sure I put it together right..
from left to right I have
the axle nut and washer, then the swingarm, the long axle spacer, then the wheel spacer, the wheel....then on the other side of the wheel, the wheel spacer, rear caliper mount, swingarm, and axle.....
is that right? should there be something between the swingarm and caliper mount?
not sure why its dragging....the caliper is working...

Never shim the rotor, caliper bracket yes but never the rotor and first I would make sure the rim is centered properly.you need to remember that not all after market products are machined properly...

First I would call Ultra they could have sent you the wrong spacers.Your problem is the alignment of the hub not offset of the rim. Find which brake pad is dragging,that will tell you which way you need to space your hub. Remember if have to add to one side you have to take away from the other. You need to check your belt alignment also.

That is a "fit all" wheel..it is not a direct replacement for anything...that means it will require custom spacers to work correctly. Mount it with out the brake pads and see what it will take to center the caliper over the rotor...you also need to check that the wheel is actually centered in the frame...space as needed to work correctly...and spacing the rotor is OK...have done it many times with no problems.

Bleed the brake, to remove any surplus fluid and reset the pistons. Operate the brake during the process, so the pistons move and settle back correctly. Treat the brake the same as if you had put in new brake pads, see if that helps.

Yes and check it is the brake and not crushed wheel bearings.
