Defective brakes on 7 month old TT
We took our KZ TT to the dealer to get a few warranty items attended to. Just got a phone call from them saying the brakes are all contaminated with grease inside the drums and all the parts need to ...

I have a one month old Coachmen Freedom Express 246RKS. I've had quite a few RV's, and when I get a new one, the first week or two is spent making improvements like new TV bracket, Blue Ray player,porcelain toilet, better mattress etc. When all that was done, I set the load distributing hitch up and took the 30 mile ride to get the whole rig weighed. When I got there, (this being the first time I pulled it, as the dealer is two miles from my house, and I brought it home with a standard ball and shank), I felt all the hubs, and one was very hot. When I got home, I took that wheel and drum off to see what was going on. I had already checked the brake adjustment when I pulled the wheels to have them balanced, so I knew that wasn't the problem. The hub was completely full of grease, and it had gone thru the seal and into the brake assembly. I took it all apart, cleaned everything, repacked the bearing with red high temp grease using a power packer, and put it all back together. Took it for a long ride, and hub is now cool to the touch-no heat whatsoever.
So, it does appear that Lippert is now filling the hubs using the Super Lube spindle. The grease they use is watery. Today, I did the other three wheels, and found one more that the seal had failed. Prior to this, I didn't have a strong feeling about the Super Lube, but now I will never use it again. When whoever filled the hubs did so, I imagine they just pumped them till it came out and filled the grease cup, and no doubt didn't bother to have the wheel rotating while they pumped. I believe the system can work if you pump very slowly while someone spins the wheel, but I don't see the benefit over just having properly packed bearings. In my case, since I wanted to get rid of the cheap black grease, I needed to take everything apart, clean it all, and put it back together. I'm surprised you don't see more bearing failures, knowing this is the way they send them from the factory.
