anyone had brake actuator repair?

[layne]

I called our dealer to ask about the repair on this and he said they have to test it and make sure it needs repair, then order the part which takes about a week, then make the repair. They are about 250 miles west from us so it's way out of the way, plus we are planning to head east in a couple of months. Has anyone had this repaired? How do they "test" this to know if it will fail later? The service guy asked if we'd noticed any trouble, but we came straight from the RGV so really haven't towed it very far in the last few months. Do we just wait til it "fails" then take it in to a dealer somewhere else? We don't want to make a 500 mile round trip just to see if they might need to repair it.
