alco hub replacement

Why change the hub? You have removed the brakes. I have recently done just that on a trailer. The bearings cost £24-00 & I had to buy some new bolts for the wheels, as the old ones had severely rusted. I also had to purchase a tap £ 6-00 plus postage from Tracy tools to clean the threads for the bolts. Once tidied up it all worked OK.
If you are really worried, change the opposing hub on the other side so you have 2 braked & 2 non braked.
