Witht the EZ-Lube system by Dexter, you'll get several thousand more miles out of your shoes because of all the grease on your shoes.....cuts down wear ya know...Just kidding...So in reality I've noticed the Chinese made brake assemblies tend to "chunk-out" more so than the Dexter USA made units. 10k does seem a little low...Ok, a lot low! Can't look right now but it seems you said your coach is a 2002? It may have had Dexter's already....at which point I have no logical explanation for ya'alls...........unless your brakes are way under sized,
