Rear brake delete

For those of you who have done a brake delete, have you had any issues with the splines on that side rusting or stripping out?
 
I have already followed a good how to on the brake delete, but the fact that the hub on that side will now not be within an oil seal I am apprehensive about the splines rusting.
 
I just lost an axle and ring gear because of water  got to my axle splines and caused corrosion.
 
Thanks in advance for any input!

    this is on a 2015 rancher FM.
     
    I have tapped my axle tube and plan on filling it with grease once I reassemble everything.

    I got everything put back together and I feel better about it now, the brake delete turned out good and I have filled my axle tube with grease, only issue I have is I think I put too much grease in the left side and it pushed my seal out a little.
    I'll post pics soon.

    I'd like to see pics of the right side.
     
    I've got a 350D rear I'm putting in a 300 and it didn't have a brake drum.  Backing plate is rough but the center section is good, so I'm thinking about just grinding it down to a brake delete, and just running with the bearings on the right side and the hub on the end.

    So you did grind down the drum and slide it up on the splines?
    Has anyone run with nothing in place there?  Just the backing plate/bearings with a gap and then the hub on the end?  Any real reason to put the drum on there?

    I didn't want to run without it because the drum actually runs inside the seal and without it there would not be anything to stop debris and water from entering the axle.

    I haven't seen a late model brake assembly, but on all the earlier bikes there isn't a seal between the drum and backing plate.  Just a bearing with a seal between the races, and an inner seal in the backing plate where it attaches to the axle tube.

    Here you can see the surface that rides inside the seal on the drum.
     That drum is a heavy piece too, probably close to 15 pounds.

    But the drum butts up against the backing plate, and there isn't any rubber on the backing plate for that center surface to seal against, so it doesn't look like it would do anything to seal water out.

    Jeepwm it has been awhile but I have seen a disk brake conversion for the rear drum of the Honda's. I believe super ATV makes it and it fits most all drum style setups. I was wanting to try it on want of my 350D axles but just haven't had the time to do it yet. So that might be an option for you as well.

    I looked hard at those when they first came out.  The problem seems to be they are only cable operated, so they don't stay in adjustment long.
     
    Some people have converted to hydraulic by using lines and a left handle/ MC from other brand bikes and that seems to work better, but still not great.
     
    If it worked, I'd be all over it, but I don't want to drop $230, then do a bunch of fabbing, and still have rear brakes that don't work very well.
