Hot wheel

If the brake has been backed off, it may be a stuffed wheel bearing, get it checked by some one other than your very very good van repair person.............................

I would be very careful towing it as that sort of heat build up in 4 ks is a sign that all is not well and you may be very close to seizing the bearing and maybe losing the wheel. Good luck.

Hi Omaa,
I would be looking at the wheel bearing ,,maybe adjusted too tight or the brake shoe needs backing off somewhat.
Good luck,Cherry.

I agree with the above, put your photos in photo bucket or similar then copy the link into the insert images&files button below, you don't have to be a member.

You don't mention if there is any unusual noises coming out of the offending wheel, at say walking pace? This might indicate a malfunction of, or collapsed, braking mechanism.

111 degs? In only 4 kms? That's serious heat, so wonder if there's any grease in the hub, or as suggested by the others, grossly over tightened bearings. To isolate the fault you need to find out whether the heat centre is the hub, or perhaps the brake drum only. Be prepared for slightly blistered fingers. :-)) Use back your hand to test this, less risk of being burnt.

Also find a repair person who is practical, rather than very, very good, and ask them to check the condition of that hub, bearings and any contents therein. Another thought, the stub axle wouldn't be bent, causing the wheel to run off centre?

Omaa, you have answered your own question, it has to be a brake problem, even though it has been backed off............ Check wheel is rotating with the brake controller off and then on.

If its only 1 wheel it is NOT the controller. It is a bearing or backing plate problem and it could be that the backing plate is not alined properly. I have had the same issue. Barnray

If a bearing was causing 111C in 4km, it would not make the 4km home again.
If something else like a backing plate was doing it, it would be screaming and you would hear it from the driver's seat.

Has to be the brake.

Look at in another way if the controller is working and only ! wheel is doing the Job for a heavy Van. B

I have had 2 new backing plates installed in my trailer which worked in the driveway but were s*** on the road and found that the magnets from new were not square to the brake drum so would not activate the brakes properly.B

Bruce has read all of replies & says thanks. Shall see what happens on 13th & will keep you informed.

Just a quick point. You say that "it is the back right hand wheel" " The ones on the off side are fine"
Have you actually shown the repairer which wheel is the problem. Reason being, "off side" is right hand side. Near side is left. The repairer may be looking at the wrong side, based on your description of the problem.

Following this post.
Hopefully it's not one of those where the OP fails to post a follow up once the fault and solution have been identified.

My suggestion is to first drive for that amount of distance and don't touch the brakes, this will tell a story in itself. Secondly, pull the brake drum and have a look at the brake magnet and shoes. Then disconnect a wire from the brake magnet an take the van for a run. This will tell you if it is a brake problem and it should show up again after the wire is reconnected. In my eyes after the mechanism (magnet and shoes) are checked the only way that brake can be come on after it is backed off is the magnet is receiving voltage from somewhere to activate it, in this case so should the other brake as it should receive a parallel feed.

At this time I would be replacing or servicing the bearings and seals and having a good look at that stub axle as well. Maybe a silly thing, but I would also make sure your suspension is working correctly and not putting all the load from that side on that wheel and tyre, I am sure it has the correct pressure in it.

Hi Omaa

I feel you frustration as have had similar problem myself. Mine ended up being a faulty brake magnet as when the magnet was replaced the problem was gone. Why or how I don't know, but maybe swapping the magnet with one on another wheel and seeing if the problem moves to that wheel would at least comfirm that the magnet is not the problem.

As posted earlier , it could be that the one wheel is doing all the braking.

To check the magnets, take the drums off and slide the voltage controller completely on, and have someone keep it there.

Go around the brakes with a 10 inch shifter and see if each magnet will hold the shifter without it dropping off.
Good ones will , bad ones won't.

Told to me recently by a trailer and caravan maker, and tried at home and it works.

I about to show Bruce the last few replies from the past 2 days & I certainly will post back here when & if they get fixed.

If there's no current to the hot wheel brake I believe the shoes will rub. Jack that side up and spin the wheel.
