Recently there was a discussion about trailer brakes and I asked if there were any known conversions of swapping drum brakes for disc brakes. This is a common maintenance item on classic cars that are used as "drivers" instead of "trailer queens". The only response is quoted below. I am hoping that this discussion might invigorate a mechanically inclined individual into taking up this challenge

I don't think there is such a kit. From what I remember when I was checking all that stuff out a couple years ago the disc brakes require more psi to operate so the electric/hydraulic actuator is different for drums than it is for discs. Of course you can buy everything to do all the stuff you were talking about..... I think I can find links I had saved if you want.

I can't help but wonder what an improvement a disc brake conversion would offer to an older trailer. It would seem that a supplier of trailer brake hardware would bundle the necessary parts into a kit, to retrofit a drum brake design. If mechanically it were not easily accomplished, because of the welding or machining of parts necessary for the installation of the modifications, couldn't an adapter be fabricated to marry the new and old?
A worse case scenario would be to swap out the axles with the new brakes installed. As expensive as that might be, it would be still less expensive than the purchase of a new trailer, particularly if you were still pleased with your present trailer.
I just called a large trailer sales in Eastern OH, and received a lot of silence and possible maybes. They were not prepared to perform such a service, they knew of no modification like this being performed and couldn't get off the phone soon enough.
I'm now too infirmed to do this myself, but I think it is a possibility that might be encouraged. It has made the operation of classic automobiles much safer, and has brought modern standards to the ranks of those, who frequently use their cars. There are many older trailers that will last several more decades. I plan on that for mine. Having an additional safety margin would be a small price to pay.
