I have a 2020 Jayco Eagle FW 317RLOK. In two years I've towed it approximately 7500 miles. I took it in for my yearly NY State inspection and the brakes FAILED. What type of mileage should I be expecting from the brakes installed by Jayco? Something seems wrong. I would think I would get more mileage than this out of a set of brakes. Any info would be appreciated. Thanks.
