Thanks,for the replies. It’s funny. I had no idea that those brackets,for the slave cylinders existed. I just bolted the stock brackets onto the,frame. They work beautifully, but i knew something wasnt right, lol.
As for the seat mounted lever, i jerry rigged that. Basically i took a 1/2 inch rigid conduit and cut it to about 3-4 inches and wrapped it in electrical tape because tge 1/2 inch is too small and the 3/4 is too big. The tape also serves as,a bushing and will hopefully allow a small amout of play to avoid breakage. I then took 3 conduit hangers and attached them to the seat,with short sheet metal screws. The lever attaches tp that conduit held in place by the hangers. The hangers allow for some movement of the brake lever apparatus under more torque than would be provided in normal riding conditions. Again, the hope is increased durability.
Heres a pic of the conduit hangers,im talking,about:

I don’t have a pic of it right now, but i can provide one later. The makeshift,brake lever mount works great and has handled some good falls without,question. Only time will tell on longevity, but i think it will last awhile.
In case anybody else is jnterested in adding,magura,to their machine, here are my 2 cents:
Do it. It’s a,game changer. I have been riding for 8 years (having,taken a 3-4 year break) and i have no idea how ive been riding brakeless,for so long. I had,no learning,curve, they felt natural from the get go. Taking one finger off the saddle and deciding which finger,felt awkward. But it Only felt awkward, and despite that my riding and,confidence both saw,improvement. I am still sore, but my knees dont have that super super painfully sore feeling. Everything,jist feels like healthy soreness.
I find it interesting my unicycle came with brake mounts and powdercoqting on the sidewall of the rim. My hope is that the brakes will break the sidewall powdercoat so to speak and expose the bare metal underneath for alincreased breaking,power.
