Major brake problem

You might have seen my post in the FBTS owners thread. New unit and left front brake got up to 375 the other three 125-140 on my heat gun first stop. I backed off the adjuster on left front with no effect on temp lowering. Once home jacked all wheels and all spun freely. Short trip to dealer the left front 250-275. Dealer just called and left front is totally ruined even the rim. The other three drums are grovved and linings shot. The axle and spindles fine. They r putting in a claim for all new drums, shoe Assy and bearings. So what happened. The other three never got hot but are wore out. No problems on my last Rv and brake controller works fine zero voltage when driving. I have a feeling who ever towed my RV from factory to Tampa cooked the brakes somehow. The other three never got hot for me at all and should of been fine. If somehow a stray voltage was getting to the magnets than all of the brakes should of been super hot. That is why I think who ever towed it here might of had a bad hook up and toasted them all. I asked if I could get the non self adjusting installed which r cheaper. Anyone have any other ideas that caused this!
Tks
Rock

Other then the high temp, did the rig stop fine...or did it feel like poor braking?

After you backed off the shoes, why did the drum still heat up?

The brakes seemed to work fine, no pull or chatter. The reason the left front ran hot was the bearings were bad. I found an article on line that the brake manufacture said if the drum is out over .015-.020 the shoes will move and constantly keep adjusting. They adjusted going forward or backing. All the wear had to happen during Delievery or I would of felt the drag and the other three never got hot when checked. The only explanation is the front left had a warped drum from factory and delivery truck either had a bad controller with voltage to brakes or they used the trailer brakes set to max to stop the truck. You know it got hot when the left wheel lug nut melted into the cast alum rim. I am surprised the spindle is still good but the two trips I took I greased the center lube hubs with synthetic high temp grease before each outing.

Makes me want to get a temp gun... How else would you have suspected anything until the wheel passed you on the interstate.

I keep my laser gin in the drivers door pocket. I don't check my temps all the time, but perodically, including the tv.

I'd be concerned about the spindle that hot. I wonder if the temp was lost, I might push for an axle replacement after some research

If the wheel bearings were installed incorrect at the manufacturer (i.e. over tightened) there is no doubt that would cause severe overheating. Once high heat starts transferring to other components things start going south fast. Any chance that's were the problem originated and everything went down hill from there???

Could of been over tight from factory but that does not explain the severe wear on the other three. My first trip I forgot the heat gun and the second trip I was shocked when I stopped and found the high temp. If not for the gun you could feel the heat but would have no idea just how hot. The other three were fine and I know the 350-375 I found would not of melted the lug nut to the rim. That had to get way hotter and had to occur during delievery. How else can you explain that the other three never heated up, spun freely but were severely worn and drums grooved. I will bet they had the brake controller set to max to save the tow vehicle brakes since that is all they do is tow heavy rigs

Unfortunately you'll never know for sure, but your theory makes a lot of sense. On an up note, you didn't completely lose a wheel bearing going down the highway. I guess all you can do at this point is get her fixed and get back to enjoying it. Good Luck with the repairs and keep us updated.

Not happy right now with Jayco. Dealer called and said Jayco will only pay for one complete brake, drum and wheel and not the other three brakes. Jayco told my dealer to call Lippert
I spoke with Jayco yesterday and told them what I thought in no uncertain term. Dealer is now going up the Jayco food chain and so am I. Dealer thinks maybe the truck that towed my Rv pulled the breakaway and overheated them. Something happened how can u melt the cast alum rim at one lug nut. Smoke had to billow out of this wheel luckey no fire or blown tire. Dealer told Jayco trailer is unsafe unless all four are changed out. This will be resolved!!!

Let me add one thing about my dealers service. I have received a call everyday about my RV to update on parts on order and how things were progressing. I am so impressed with these updates. My last Rv I dealt with camping world and good luck even trying to get a return call from there service dept
