Default Baffled By Brakes

I just bought my first Harley. It's a 2005 1200c and it only has 5000 miles. The rear pads are OK but the brakes were weak. I removed the pads, cleaned it all up and returned it all to orginal condition. Now I have no rear brakes. Nothing seems to be coming out of the master cylinder. It will not bleed anything but an eyedrop. I've read a few posts here and there about the rear MC problems so I removed it and took it apart. I have the service manual to guide me along and all went according to plan until the last step. For those of you with the service manual please look at the exploded diagram of the rear master. To my surprise I do not have parts 16 or 17? There is no spring or primary cup as the diagram shows. The piston was the last part that came out. There is still something rubber inside the main body. Have I misunderstood something or is there more than one rear master cylinder type for this model?

Nice to be here, Thx.

Well there's still something wedged in there... but I don't want to poke at it too hard if its rubber.

Like you say...Its gotta be there. I'll try to find something to ease it out.

It will be junk if its the primary cup.
Can you blow air pressure backwards through it from where the brake line banjo bolt screws in ?

Ya it was the primary and spring in the bore...They look good. No damage. I guess it'll have to go to the shop now which is a pain cause the shop is 200kms away.

Oh well.

Master is a known issue from 04-06.
Ask yourself why the spring didnt push the cup out of the bore when you took it apart.
Look at the cup closely for a potential failure point in the future
