rear brakes
Hi guys, When cleaning my bike, I noticed a ton of brake dust on the rear wheel vs. the front. Also when riding I can hear the rear brake draging. Is this normal? Would the rear wheel alignment have anthing to do with this?
thanks for any feedback

Have you had any work done in the back recently? I know if you remove the brake caliper (or pads) you need to clean the pistons before you compress them, otherwise they do not retract all the way and will drag on the rotor, producing dust and heat. I know because I had the same problem. The is a guy with a company called Motorcycle Metal or similar that has a great tutorial on cleaning the front caliper, and it is mostly the same for the rear. I thought I had it, but cannot find it. If I do I will post it here. Good luck.

I added a new rear wheel and rotor. I watched the tech do the install and he really struggled to get the rear caliper on the rotor. I never saw him compress the caliper before install. If the new rotor is a tiny bit thicker then the stock it will drag. I am wondering if I should call the dealer and make them look at it? I just find it hard to believe that there is that much brake dust for as little as I use the rear brake.

When compress the hydraulic cylinders in your caliper, then put the new pad/caliper assembly over the rotor, it should be pretty darn easy. It shouldn't be dragging like you say it is. All disc brakes pads will ride pretty close to the rotor but they shouldn't drag. Sounds like something else is wrong: possibly mismatch on the rotor/caliper.
Rear wheel alignment might have something to do with. So the tech doing the job, was not at the dealer?

I had the harley dealer to the install.
Maybe it is not a problem. I just checked and both front and back have no space between the pads and calipers. In fact I could not even slide a single sheet of paper between them. I do recall my old cast wheels collecting brake dust. It is just more noticable on chrome. Still bothers me that I can hear the rear pads drag slightly until I apply the brakes.
