A local RV dealer, Brandt Trailer Sales in Dayton OH, quoted me a price of $258.00 for a complete set of 7" Dexter brakes to fit our 04 13' Scamp. For the convenience of dealing locally and not paying for shipping, I'll probably go with this. Out of curiosity, I asked about converting to 10" brakes and learned that I'd have to change wheels and tires (may not be a problem for Casitas). I figure 7" brakes will work much better than no brakes, so I'll stick with the stock size.
The 7" brakes are more than adequate.
I redid the 7" brakes on a Trillium
4500 earlier this year and I could lock the brakes up and wear flat spots on the tires
if I had wished to.
I just did a complete brake replacement on my 13' Scamp
and again if I wanted to I could wear flat spots on the tires.
10" brakes on a small trailer are overkill and a waste of money in my opinion.
I would check with a plain trailer supply company, not an RV dealer, or a suspension shop as they both will carry the brake parts you need, probably at less cost.
