Firstly I would only like replies from folk who know what they are talking about & may have had the same problem.

Secondly we have a very, very good van repair person who will not seem to accept that there is a problem.

It has been back to them3 tomes now & no satisfaction.
Maybe not willing to admit they are wrong, I do not know.

I would like to include a photo here but not able.

Stopped after about 4k this morning & showed, with laser on wheel, 111.2 degrees while the other was 33. It is the back right hand van wheel. Has tried letting the electric brake controller off but no good. The ones on the off side are fine.

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.

As John said, the bearing is the prime - if not only - candidate if the brake has been properly backed off. You can always check the brake by jacking that wheel and rotating by hand. That'll also give you a feel of (and chance to listen to) the bearing, and maybe that will confirm the culprit.

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.

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?

The heat is higher at the outside of the drum than around the bearing. The brakes are backed off 15 clicks. Have done the wheel spin by hand, runs well.
Without out the brake control on at all it does not get hot.

Pointing to brakes or brake controller, IMO.

What brand and model brake controller do you have?

Cheers

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

It also could be that the van is only braking on 1 wheel I have found that some backing plates with electric setups the magnets are not alined properly and even tho they work when tested at the shop they don't work on road

"If its only 1 wheel it is NOT the controller."

I thought of that too, Barnray, but he says if the controller is not connected the wheel doesn't heat up. ????

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.

Cheers,
Peter

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

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.

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 all, agree with other suggestions and...the mention of disconnect wire makes me wonder (? a long shot) is wiring correct.. if there's incorrect multicore wiring or a short may allow current into one side of brake and activating it? use a multimeter to check.

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.

regards Kc

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.

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