I bought my RV new in Jan 2020 and put about 10,000 miles on it. We want to travel to Canada this year if the border is open. My question is about the brakes. Is it necessary to have them checked at this point for wear? I am thinking this is no different then a car that has brake drums and they should last 20 thousand miles before needing any maintenance. They currently work just fine. Also what about wheel bearings. Do they need to be repacked?
