Hi Steve,
I was able to do some research and find all the parts you need; they don't all come in a kit though you can get the parts individually with the following:
- Trailer Hub and Drum Assembly # AKHD-545-35-G-K
- Trailer Idler Hub Assembly # AKIHUB-545-35-G-K
- Bearing Buddy Bearing Protectors # BB1980A
- Hydraulic Brake Kit # AKFBBRK-35-D & Mounting Hardware # BRKH10B
A couple of things to note, one of which is the Bearing Buddies are sold in a pair and not individually, so keep that in mind for the Quantity when you check out. And while we don't have the exact Flush Kit you mentioned, we do have a similar option to bleed your brakes, the Powerbuilt Brake Bleeder - Master Kit # ALL648591.
