The electric brakes I put on the trailer cost under $300 for all the parts in two hours of my own time. They worked more reliably and gave better stopping characteristics than the old Disks. The old disks caliper holders have a fatal design defect and can fail catastrophically with no warning. The welds fail due to fatigue factures. I had one scatter parts and oil all over the road and I when I took the other ones off I found two others had the start of the same fatigue crack. The new disk brake systems are designed and made by a different manufacturer.
If you insist on Disk brakes, buy a whole new system. Be aware, that Airstream also made an error on assembling this system also and worn through and crippled brake lines have been reported. Most other trailer manufacturers use the standard electric brakes and they are easily maintained or repaired anywhere in the country.
I have never heard of any owner having that many problems with the original Excella-Vac disc brakes.
They are really OK, but at this point old and out dated. But the rotors and calipers have always been out standing. Can't say the same for the Actuator, but at this point, the Actuators can be replaced.
Typically however, a set of 4 brakes and 4 hub and drums with new bearings, would cost about $600.00, or more, plus shipping.
That's close to the cost of a new actuator, which given a choice, disc brakes are indeed far superior to electric brakes, hands down, any day, any time, any where.
Down grading from disc to electric brakes, is a huge step backwards, for a travel trailer braking system.
