Today, we heard the rubbing/grinding of the right rear brake. We went to a truck and trailer company for inspection. Sure enough the brake parts (tension spring among others) were damaged. Since it is still under warranty, he disabled that one brake, leaving the remaining 3 for us to get home- where I can take it to the dealer. Cost $100, hopefully Jayco will reimburse. Don't know if that is feasible for you, but it worked for us. Also, if you're still in the Denver area, a lot of RV and truck repair shops north of Denver along I25, from Frederick to Longmont.
