Guys my 2017 Phoenix Trailer is giving me fits. To start off I have replaced the bearings, hubs, brake pads and calipers. I have bled the brakes numerous times I don't believe there is any air left in the line. When I come to a stop there is an incredible squeak and grinding sound. Upon inspection there isn't any over heating that I can notice. I have checked the calipers and I don't believe they are sticking. I am at a loss any ideas?
