That was the first thing I did. Pulled the boat this AM for about 40 mins to the launch. High pitch squealing at speed (seems like after pads warm up). Wheels were very hot to the touch at launch and still had burning rubber smell (like pads burning). On the way home, we experienced the same problem, but squeling was intermittent. Wheels were very hot and rims were black from the pad dust. There was a faint burning smell, but not as bad as in the AM and yesterday. I checked the fluid in the cylinder yesterday and it was low (refilled it). The cylinder was full last week after the new brake lines were installed. I have owned several boats with dual axle brakes, so I am familar with how they work. I will call the plant on Monday and talk to Rick about it.Mike Caponigro Cary, IL 2010 Jaguar/ Merc 250 Pro XS http://www.xtremek9.com
