When coming onto an obstruction in the road, such as a pot hole or hash bump, etc.. in the road way, DO NOT have the brakes applied when hitting the obstruction if safely possible. Brake aggressively before and then release the brakes if possible and roll over the obstruction. More suspension and tire damage has been done when hitting something while braking, may not be immediate, but it has occurred and will show up later. I the instance of hitting a pot hole, when the brakes are applied through it, the wheel will become light, if not air born, going into the hole. With the brakes applied, the wheel will stop rotating and will hit the back side of the hole and cause an abrupt hit on the tire, wheel, bearings, suspension, etc.. The suspension will be wrapped up from the braking action and will have less give when the brakes are on because they are already adversely loaded for such an impact. If the wheel is allowed to roll freely through a harsh jolt, you have a greater chance of coming through it undamaged. Yes you may have a jarring jolt that shakes stuff up, but you may avoid a catastrophic failure.
While you didn't mention it specifically, this is the correct advice for any vehicle at any time, whether or not pulling a trailer.
