Rear brake seems useless
I have a 2010 ultra with abs the rear brake works but not well I've changed pads twice and changed fluid once thinking it might be bad the pedal feels normal and no abs light on the dash. The dealer claims I need a complete brake service and a reset with the computer for a total of 200.00. I'm a pretty good mechanic and confident I didn't get any air in it when pushing new fluid in I even checked the rotor and it doesn't seem to be glazed. But I'm thinking it may be is there a way to unglazed it while still on the bike? Any hints

Sure. But watch your fingers. Get the back wheel off of the ground, remove the bags and whatever else you need to, to get your hand on the rotor. Start the bike, drop it into 1st gear and put some 40 grit sand paper to the rotor. Watch your fingers.
Use a sanding block, not your fingers. Use a helper to keep the clutch engaged just enough to spin the tire. Oh yeah, watch your fingers.

I can feel it start to stop the bike but fades fast won't hold on a hill unless I lean on them hard mostly I use my gears and the fronts but I'm concerned I case of the need for a sudden stop would be nice to know the will help unless it just the nature of the beast. I know the single disc can't be compared to the duals in the front but I think they should do more than they are

Think it's got something to do with the rear caliper design harley uses, rear brake on my 17 RK leaves a lot to be desired, think I'd have to literally stand on it to lock it up and I don't have ABS.
