Tires are easy to check and see if they are inflated properly. Rusted slides on the brakes or swelling brake hoses are harder to see. I have had both of these issues. If you notice that your MH pulls to one side as you apply the brakes change the hose on the opposite side. The slides you can check by jacking the tire of the ground and spinning it and applying the brakes,then spin the tire again and see if the calipers release. If not clean the slides. While you have it jacked up check the wheel bearings by spinning the tire and see how much play is in the tire.
