Need Some Brake Help - Hot Wheel

Hello. Here is my brake story...

I replaced the backing plates/brakes on our '05 30 foot Classic last month (low-bid Chinese made). So, this weekend (Thursday through Tuesday (today)) my wife and I went on a short get-away to Diamond Point, WA (close to Sequim). From our house it is about a 40 mile drive. When we arrived, my wife said "what's that smell?" Smelled like hot brakes. We felt the wheels, they were all slightly warm, one was HOT, could not hold my hand on the wheel for more than a second or so.

We parked and set up the trailer all the while I am wondering what could be wrong with this one wheel/brake. We slept on it, the only thing I could think of is that the brake was adjusted too tight, the bearing was adjusted (way) too loose, or something broke.

After breakfast, I broke out the Van jack and jacked up the trailer (a scissor jack, about a thousand turns on the screw - at least that's what it seemed like). The tire's off the ground and it turns easily with just the right bearing play. Hmmm, what could it be? OK, I'll take the drum off to see what the brake guts look like. Looks fine to me. The actuator seems to move freely and the brake shoes move out appropriately.

Put it all back together and sleep on it some more. The only other thing I could come up with is that the brake is adjusted too loose and the actuator is moving too far and jamming the brake on and not releasing. So, this morning before leaving I pulled the trailer onto a pile of leveling blocks so I could adjust this brake. It didn't seem to take very much to get it adjusted to just a slight brake rub.

So, off down the road, I am keeping the brake controller adjusted for very light trailer braking. We stop about seven miles along to check temperatures. The wheels are all cool, all of the brake drums are hot, but not burning except for the one that is acting up. Before pulling away, I backed up a bit and applied the brakes in an attempt to release a jammed brake (if there was one). Another seven or so miles down the road we stopped again. This time the acting up brake/wheel is hot to the touch, the others are barely warm. Just arrived home without any incident (thankfully).

I am wondering what is up. Did I get a defective brake assembly? It makes no sense to me.

Any ideas would be appreciated.

Thanks,
David

Wish I could add some constructive comment - it surely sounds as though you are checking all the right things.

Presume that not only does the wheel spin freely but that it does not have any undue roughness or noise that might indicate a bearing going bad?

Yes, the wheel spins freely and smooth, bearings look fine. Thanks.

In order for one of the wheels to get hot, there has to be a source of heat. That's idiot-simple, but since I'm an idiot, I have to start somewhere…

Possible sources of heat:
1 - Brake shoes rubbing on brake drum. You say that the brake shoe is making very slight contact, and you adjusted it that way. Is it supposed to make contact? Here's the way I was taught to adjust drum brakes:
Quote:
Tighten the star adjuster while rotating the wheel in a forward direction until the wheel reaches a point where the brake shoes start to engage. Loosen the star adjustor one click at a time while turning the wheel in a forward rotation. Continue adjusting one click at a time until the wheel turns with little effort.
In other words, there should just barely be no contact when the brake is adjusted properly, and the absolute minimum brake motion is required to bring it into contact.
2 - Wheel bearing in need of lubrication. Have you actually looked at the bearings, or just spun the wheels to check the bearings? If the bearing needs grease but isn't badly worn yet, you wouldn't necessarily detect any wobble in the wheel.
3 - Tire is low on air, which leads to excessive sidewall flex. In such a case the tire would be hotter than the wheel.
Just to cover all of the bases.

I will bet that it's not the brakes.

It's the wheel bearing. Trailer axles need more play than your car or truck. If you grab the trailer wheel and it feels nice and firm, eg, maybe the edge of the tire moves slightly under your hand pressure (like your car), it's too tight!! Loosen the castle nut two or three notches until you can produce more movement than you are comfortable with, maybe 1/4" at the edge of the wheel.

I had this problem, finally got good advice about trailer bearings, and I've had 20,000 uneventful miles since then.

Perhaps it's the other three brakes that are out of adjustment and this one wheel is doing most of the braking.

OK, I took the brake drum off again. Everything looks fine in there, the shoes are on correctly (front/rear), the shoes move out when I move the actuator arm and they move back when the arm is released. The power and ground are both fine.

The only thing I can see that looks different from the others I have checked is that the actuator arm seems loose on its bearing. For the others I have checked the actuator arm has very little (no) side-to-side movement. This one has about a quarter inch side-to-side movement. I wonder if it is flopping around and actuating the brake some. I was reading threads on this forum and someone else had a similar issue with a loose actuator arm and a hot brake drum.

I installed the four backing plate assemblies the same and this one is the only one that is acting up. I think it needs to be replaced.

One more note, when I pull the emergency brake pin on the tongue, the magnet energizes, and when the emergency brake pin is inserted back, the magnet is de-energized (not magnetic).

Thank you all for your thoughts, I think it is just a defective unit.

I had problems with brakes dragging. They can drag if adjusted too tight. They heat up and get even tighter. I had to back off the adjusters. I also had a seal blow from the heat. This problem is more common with old brakes.

Hi, I was also thinking along these lines. Three brakes not doing their job and one being overworked.

They will stay on all the time if adjusted too tight.

When I jacked the trailer up yesterday, the wheel turned easily with very little (slight) brake drag. The brake was not adjusted too tight.

As for the others not doing their part of the braking, even when I had the brake controller adjusted for no trailer braking, the suspect brake still got hot.

Return to my post #4, this thread. There shouldn't even be slight drag when the brake is adjusted properly. Rather than being just barely in contact, it's supposed to be just barely NOT in contact.

You're welcome to disagree, but why not just try it? Back off the brake adjustment slightly, until it's just one click away from making any contact at all without the brake being engaged. Then see if it still gets hot. Don't worry, it will still make all the contact it needs when you apply the brake.

Protagonist,

I appreciate your concern and idea. When I put the assembly on at first, there was no (zero, zip, nada) drag. Now there is only a slight (how can I say very little, or less than that, even less than you are thinking now, doesn't even slow the wheel down) drag. In both cases, the wheel got hot.

I am definitely open to all ideas, I just think I have eliminated this as a possibility.

Thank you,
David

The brake is almost certainly adjusted too tight.

In my experience when a brake is set up too tight it gets tighter as it gets hot. If it is a little tight when cool it may be tighter when hot.

These assemblies are simple, if there is something wrong with it you can see it. The slight side to side movement of the arm probably is not an issue.

If the bearing is causing this much heat because it is too tight, it probably would have either failed by now or worn in to the point that it does not get hot anymore.

You are almost certainly looking at the brake adjustment being too tight.
