yeah man, thats it.
whats the plan? are you just building a front wheel from scratch? ill tell you from experience, its best to find the most complete setup possible from the beginning. it took me a month alone just to get my rear wheel together because i got it with parts missing. had to order the axle from this guy, the spacers from that guy, etc. it was a fuckin' pain. also, remember that every front axle & brake combo is usually only made to work with a particular fork, which in turn is made to work with a particular frame.
if youre a crafty dude that can machine parts & all that, then id say go for it man, try to run a honda brake in a triumph hub with a harley fork on a BMW frame.
or, just go the easy route & try to score a complete front end with all or most of its parts, or at least a complete brake/hub setup & have custom spokes made for the rim you want to run.
FYI, the conical triumph brake 71-72ish, has cam adjusters for each shoe which makes life easy when setting up the brake. some people dont like the looks of them but thats your call - it doesnt look that much different than that fancy expensive hub you originally posted. lastly, make sure you try to find the cable & lever that is supposed to work with the brake you run - it will save you some headaches down the road.
