Question:

can I convert the drum brakes on my 5th wheel dexter axles to electric disc brakes? Ive found kits but it takes a surge system and will not work on a 5th wheel. Thank You

I do not know of any fully electric disc brake systems for 5th wheel trailers.

There are electric-over-hydraulic (EOH) brake actuators that take in an electric brake signal from a trailer brake controller, such as the Tekonsha Prodigy P2 # 90885, and convert this signal to hydraulic pressure to operate disc (or drum) brakes. Such hybrid systems do require an EOH actuator, a trailer brake controller as well as all the hydraulic lines, breakaway kit and the disc brake assemblies themselves. As you note such systems are not intended for 5th wheels.

You might want to contact the manufacturer of your 5th wheel before considering so significant a modification. You may also want to take a look at the linked articles on trailer brakes and the steps and parts needed for various conversions.
