    A Harley kit will work. The key is the bore size. I know if you search it's been covered in here a few times.

    5/8" bore is for 04 and newer, front and rear.

    You might want to double check yours but it might be 3/4" bore on the rear.

    Should cost ya all of $15-20

    All you really need to change is the rubber cup and O rings.

    The rubber cups can be found many places, and online.

    I posted info on them a while back

    Question: I've recently purchased a 2006 K9. As I took it for a test ride, I noticed that the front brake felt a little bit "spongy", and didn't seem to start grabbing until I squeezed a bit more on the brake handle; more so than on my Harley. The rear brake grabbed sooner and felt more where the resistance should've been on the front. I was told this: "On a chopper style bike, front brake free play at the handle is adjusted to be more "loose" before you feel the caliper start to grab. This is intentional for safety sake, so as not to lock up the front wheel too suddenly, due to the long rake." I'm not certain that is the whole truth. What do you guys think?

    It doesnt sound right. I would check the fluid and change it first. Then look into a rebuild kit if the bleeding and or flushing doesn't work.. brake in a straight line.

    That's a new line, never heard that before!

    Like Paul said I would just check the brake fluid the front brake doesn't have that much fluid capacity so I'd just go ahead and fill it and bleed it!

    make sure you put DOT5 in after the rebuild. that's what it came with. maybe the previous owner mistakenly mixed different grades?

    If that’s the case, he needs to rebuild the master cylinder n flush the line. Dot 4 will eat the seals in a Dot 5 system

    That's true...he should be able to notice the purplish tint to it, it does get clear pretty quickly but maybe a purplish hew should let him know what the scoop is.

    Thanks guys for the info, I'm learning a lot about having a Big Dog, much different than a Harley. Dot 5 Brake fluid instead of Dot 4. I will make sure the service personell double check EVERYTHING Before I pick up the bike this Saturday.
