This is the price I got from "Stop your trailer" about three years ago. Mounted the Pump, ran all the brake lines (hard lines) and wiring while still using the trailer. Swapping the hubs and adding the flex lines only took one day. Disk brakes make a tremendous difference.
(From "Stop your Trailer" )

This is a fairly easy change. Running the brake lines was the boring part. Price, I'm sure, has gone up .
In any event call Bill Halasyn at 813-363-4685. He can help you....
