I am dealing with Dave Schumann at Airstream and the dealer that performed the work. The original recall was on units that came from the factory with disc brakes. I contend that if an authorized dealer performed the work they should also cover those trailers as well.
Roger Williams Airstream, an authorized Airstream Dealer and Service Center installed the ActiBrake unit, and the Kodiak hydraulic disc brakes in 2007 (which is during the recall time period).
I spoke to the Kodiak folks they recommended the Brake-Rite unit. My son and I installed the unit without any problems. The best price I found on-line was $549.95 at Pacific Trailers and it was drop shipped from the mfgr.
History doesn't repeat itself, people do!
