I have a 2008 boat I bought last fall. I have bled the brakes and greased the bearings, but I will be pulling the boat this summer on vacation and want to prep the trailer. It has hydraulic surge brakes on the rear axle. Can I have the rotors turned just like a car when replacing pads? I am going to repack the bearings and install new seals. Is there any reason to replace the bearings if they are not damaged? Tires are approximately one year old and are wearing evenly. Is there anything else I should inspect and/or do?
