Shutter under braking
We recently purchased a 2001 36' Monaco Windsor. On our first trip we noticed that the coach had a shutter that was felt in the steering wheel under braking when traveling above approximately 45 mph. The tires on the coach had less than 5k miles on them, so we returned to Les Schwab where they had been purchased. They re-balanced the front tires and sent us on our way. No improvement. After conferring with several friends, they suggested that I take the coach to Troy's Diesel & Truck Repair in Molalla Oregon. After a brief conversation with them, they were convinced that they knew what the problem was. Our coach has drum brakes on the front so they simply jacked up the front of our coach and loosened the the lug nuts. Prior to re-tightening the lugs they had me enter the coach and firmly apply the brakes so that the brake shoes centered the brake drum onto the hub. Problem solved. They explained that most tire dealers do not use this simple technique. They said that due to the weight of the wheel, tire, and brake drum, it will not center itself via the wheel studs. As a result the brake shoes do not hit the inside of the drum evenly during braking and results in the shutter. We are sure that many of you already knew this trick, but there are possibly others who do not. Hopefully this information can help someone else. Thank you to Troy's in Molalla, if you live near there, look them up if you need help. They will certainly get our business again.
