2007 FLHTC Front Brake drag
Need help guys,
Front brake (L/H) drags...
1. Cleaned dust..etc etc..didn't work.
2. Rebuilt both brake calipers...seals, and new pads
3.Checked disc for warp.none..(if I had any it would pulse when braking)
4.checked and rechecked axle spacers and alignment..
I even ops checked the brakes off the rotor, just used a piece of metal as a rotor
Funny part...
When you pull the brake handle very slightly the dragging goes away.
I rode the bike to work (30 Miles) and did not use the front brake and the L/H disc is about 20-30 degrees warmer.
You can hear it dragging 10 mph and below...
I'm gonna rebuild the brake calipers again and try it if you guys don't have any other ideas.
Thanks in advance, once again I can count of the forum for results

Mine has done it since the beginning, so did my Wide Glide, doesn't appear to hurt anything other than being annoying. Here is a how-to from Lyndall brake pads on this, but sounds to me like you've pretty much covered the bases.

I am having a similar issue I just noticed yesterday on my 2005 RK. I just put new tires on it a few weeks ago. I've probably only put 200 miles on it since I got the tires put on, but yesterday coming home from work I noticed it. Something on the bike sounded like it was howling a little I thought that maybe the belt was to tight or that I was just hearing the nice new tread on the tires. But then once I came up to a stop light and started slowing down I could really hear it up front. I got home and ate some dinner and then took the bike around the neighborhood and did not touch the front brake for the 10 min that I drove it around. When I pulled back in the garage the front right rotor was Hot and the left was cool.
Did you ever get your problem figured out? I am assuming that I am going to have to pull the calipers, but I have never rebuilt any before so I have no idea what I am getting into...
Thanks

Mine are dragging enough that when the front tire is off the ground it does not spin freely and takes a bit of muscle to get it to turn at all. I just finished rebuilding my calipers and I am going to flush the brake fluid in the morning and see if she is good to go again or not. While reading through the manual tonight before putting the calipers back together I noticed a Warning that says
Then the step that follows says.
I should mention that the step before the warning has you removing the cover from the master cylinder.
I guess I will find out tomorrow if the calipers did the trick for me.
Phil
Verify proper operation of the master cylinder relief port. A plugged or covered relief port can cause brake drag or wheel lockup and may lead to loss of vehicle control, which could result in death or serious injury.
Actuacte the brake lever. A slight spurt of fluid will break the surface if all internal components are working properly
I guess I will find out tomorrow if the calipers did the trick for me.

I ended up rebuilding both calipers,new fluid,new pads, (relief port is "ol Faithful"),
I found the brake pads had slight wear on the alignment pins, yes one is slightly slotted. This caused the pad to **** alittle, verified this inspecting old brake pad one corner was not as worn. I found this out after the caliper rebuild as my original brakes were only about 15% worn compared to new set (over 30K on them).
But with new pads installed it is alittle quieter and I rode to work (30 miles) with no front braking and the L/H roter was slightly warmer than the right.
It is still louder than "normal" but I'm still working on it.
I'm going to mess with the anti rattle clip next for tension....
