Brake surging solved
Since day one my 2010 Street Glide has had a mild front brake surge that was more noticeable at slower speeds. After a bit of post searching and troubleshooting I discovered an interesting problem that I haven't read about and thought I would share what I found. The first thing I checked for was a warped rotor and found that both rotors had no noticeable issues. Second, I inspected the pads by removing the dust guard from the back of both rotors and both sets of pads had plenty of life left. Then I looked at both rotors from the front and that's when I noticed something. The left caliper looked off center and the rotor appeared to be rubbing against the inside jaw of the caliper. After I removed the caliper, I found my observations were correct. I thought to myself, "Is this a design flaw or is something not set correctly on the left fork leg?" Well, I decided to use the simplest fix and put some thin washers between the caliper and the fork mounting holes to move the caliper toward the center. It was just enough to clear and center the caliper. After a quick road test the surge was gone. So, if any of you are having this issue and haven't found a solution, this might be worth a try.

Did you think to check if the axle was installed correctly?
Sometimes, the axle is not pushed deep enough into the recess beneath the end cap on the front right fork, or the wheel not being pushed far enough onto the axle at the left fork, either of which can leave the wheel just a tad off center between the calipers. I will tap the axle from the right side of the bike into the fork tube, and then tap the left fork tube into the wheel/axle assembly, to ensure the axle is fully seated, before torquing the cap screws and axle nut fully.
Just a thought...
