If you have a "Fleetpride' truck parts  store in you area, we found that they were able to replace the brake parts of our almost antique Newell just by eyeballing the box of parts we brought to them.This even included inside rear axle seals. Very reasonable prices, and all parts were in stock and  correct. 

Your coach being more current would have a better chance of in stock parts.

Good luck,

Guy
