Now the OP's question has been answered we could talk trailers and brakes, I feel responsible because I mentioned the over rides brakes on my simple trailer. As anyone who has ever owned a xxxxing trailer will tell you the electrics often have problems, one or all of the lights not working etc, electric brakes are no different. They will work perfectly until they don't, just have to hope it's not when you really need them. My mechanical disc, wire rope operated over ride brake is simple, easy to test and check and it just works all the time without any of the issues turbo mentioned.
As others have mentioned drive as if the trailer has no brakes and live a long life, just like flying, always have margin.
