fresh water flush system for trailer wheels

[BartW]

Came across this self made flush system for wheel bearings and brakes, for a trailer,

http://www.navis.be/forum/viewtopic.php?t=756&postdays=0&postorder=asc&start=0t

it looks easy and cheap, but very efficient and usefull,
so I thought this might be usefull to some peeps on here.

this is a Belgium motor boat forum, so the language might be difficult to understand, but the pictures speak for them selves.
The same for the new "Light bar" in the same post.

I have put a similar system on my trailer, works well and is easy to use.

I had a trailer with a similar system but did not notice any longer period between brake failures. I concluded that unless the inflow of water into the hub was enough to beat the out flow around the hub edges the effects would be limited, you could see that the water poured outof the hub only at the bottom so not mucjh of the inards was getting wet.
However the system in the pictures has a separate inlet for each wheel instead of the usuall single shared inlet so this could help the situation I describe and if you had a good supply pressure and a small clearance between drum and backplace so the drum actually fills up it could work well.
By the way, it only flushes the brake components, you would not want it flushing the bearings!
As a foot note, my view is that break problems usually stem initially from the bowden cables getting stiff, and have found that paying these some attention during the year seams to extend the service life of the brakes themselves and reduces hub overheating occurances

I looked at making a system similar to this, but after a bit of research found this company: Hub Flush
They already make exactly what I wanted and for a sensible price (imo).
Dead easy to fit and seems to do the job...

No links to teh company just a happy customer

I don't think that such a system will avoid a brake failure, if no regular (yearly) maintenance is done, but at least the flush system will avoid the salt to increase corrosion.
Each year I am impressed how the trailer has suffered from the salt water.
I think the flush system is just an extra help to slow down corrosion, especially when the trailer goos regulary in salt water.

I m a bit late to the table, here.
Trailer guy suggetsed taking off one of the wheel studs and ramming a hose in.
Cant say it saved me anything.. still had to replace cables and shoes each year, and usually most of the bearings.
