Can not read anything on what you posted. Tried to use the magnifier and it is too blurry.
Here’s an actual link... As you can see the brakes must be burnished in if they are going to work properly. I mentioned earlier if the camper was brought in on a semi trailer the brakes never got burnished in... if you don’t feel comfortable doing this yourself I’m sure the Dealer can do this for you. Show them this information.
So based on that it looks like the dealer wasnt being a butthead anb the weird thing is I looked all over my paperwork from gulfstream and couldnt find that info anywhere and in fact before I posted the thread I looked all over the internet for info and found nothing.
