can I put a brake controler unit in my import 24volt patrol and get it to work with normal trailer brakes

yes but you are betteer off putting brake controler on trailer and using your brakes as power

Most electric brakes on trailers are 12V. You can wire the brake circuit through a relay to pin 5 on the plug and install a control unit on the trailer (no adjustable in cab of course) Use a 24V relay and run 12V through the contacts this would work. Other alternitive is run 12V through relays to operate brake control unit in cab. 12V power in and relay for brake light switch 12V through contact to activate unit and then variable 12V to pin 5 for the brakes.

for reliability though I would use 24/12 voltage reducer for this kind of situation...

What sort of power requirement would electric brakes have ordinarily? what amps are fused between both wheels?(what are..fuse ratings on either actuator of each wheel?) Would you for example run a separate fuse for either wheel,so in the case of one fuse/wheel brake failing the "good" wheel still has some braking effect,whether good/bad? Or maybe one fuse blows and all trailer brakes are gone..As long as the current draw is low a 5amp 24/12 converter is all you'll need i'd say.. Cheers,Mark.

we use 12v trailer brake units on our trucks at work. we centre tap the 24v batteries to get 12v (that way you have lots of amps to play with) we then use a redarc charge equaliser to keep the batteries SOC even.
