Could you provide more information describing the damage to your brakes? Disc or Electric? It would be very unusual to damage all four brake assemblies at once unless there was either an electrical or hydraulic fault. If the brake away pin cable was to hang up on something in the bed and the pin became disconnected that could cause you to overheat the brakes and ruin all four assemblies. With the pitiful drum brakes on most of the Montanas that could easily happen without your knowledge. If you have disc brakes than it’s highly unlikely, as they would lock up the wheels and smoke the tires. Have you checked to see if that pin has become dislodged?
