I got my caravan from the storage site today which is about 7 miles from my house. When I got back I noticed the alloy wheels were really hot, so hot that I couldn't hold my hand on the wheel. I have a AL-KO secure wheel lock which fits in the spokes, so I often notice that the wheels are hot, but never as hot as today. Both wheels were as hot as each other. I checked the car and they were similar tempreture? Is it just becuase the air tempreture is so hot that it effects the drum brakes slightly differently?
The van is only a year old and has just been serviced.
My concern is that I'm driving down the south of france in a couple of weeks and could do without a problem!!
Assuming your caravan handbrake wern't on, possibly brakes binding, but could have just been heat from braking. Way to check, drive down quiet dual carriageway for some miles. Slow down in good time & try stop gently in a layby without allowing caravan brakes to come on. Get out & check, wheels/drums should be cold.

it does sound like brake bind,just possible you have let the handbrake off and the linkage is still pulled on.do not leave for holidays without checking at the dealer as overheating can melt the one shot nut and you could lose a wheel.seen pictures of this twice.
------------- the only silly question is the one you do not ask.
If it's just been serviced I'd ask the dealer/workshop if the might have overadjusted the brakes. Make certain your handbrake is off & see if you can push the van without undue resistance.
Some years ago a friend of mine arrived on site & asked me to put my hand on his car hubs. They were red hot, his caravan hubs were stone cold. On investigation, it was discovered that his caravan brakes weren't assembled correctly & his car had been doing all the braking on his 200+ miles journey. This was the first trip out for his brand new caravan after just being through its PDI. He was not happy!!
I'd ask the workshop about the adjustment on yours before heading off to France if I were you.
Could be caused by a wheel bearing. A binding brake is more likely, or the hand brake was on. Is it possible the brake was pushed on by a spare wheel on the car? Whatever the cause, it will need to be checked out, even if the problem turns out to have been a simple matter of the hand brake being left on as there is likely to be damage to the brake shoes and possibly the drums.
It may be you have 2 different problems here,as you say all 6 wheels were as hot as each other.Check the van first by jacking each wheel off the ground and spinning it to make sure they spin freely.The car the same as I can't see any connection between car and van, unless you braked for some distance just before you tried the temperatures of all 6 wheels.If the brakes are binding on the van this wouldn't effect the the hubs on your car. Are you sure it was the hubs that were hot and not just the tyres? as it has been very hot weather.

Is there a significant down hill section to your drive back home, or did you drive with vigour? These will cause the vans brakes to come on and they will heat up quite quickly; this is normal. Running hot is not in itself abnormal they will if the brakes are being used. As you said the tow vehicle brakes were hot then it points pretty well to you having been braking so the van will have been doing the same and its nothing to worry about.
As "Tentz" said check after a flat steady straight drive one not requiring braking where you slow gradually. Then they should be no warmer than washing up water.
Even a slightly dragging shoe will soon cause a drum to heat up significantly. As they have been recently adjusted things might need a slight re bedding, re-centring. If you suspect this, brake hard a few times to try and bed the shoe and let things cool down well before re doing the above test. If it is not then cured, you need to contact the person who serviced the van to get things eased off. If there is a significant rub it can ultimately do a lot of harm but this ought to be very evident with a literally "stinking hot drum" way beyond too hot to touch, if its just a minor rub it should re-bed quickly after a bit of heavy braking. Its not unusual for a reset drum brake to run a bit hot after being adjusted a little too tight but this ought to quickly sort itself out.
Ako's ATC and BPW's IDC systems can be another cause of your caravan brakes running warm, especially if the van is not very well loaded, which will make it unstable, therefore causing both systems to be working far more than usual.

Our tourer days are over and we have moved on to a Hobby Motorhome
It may just be because of the heat, the other year on the med I was amazed at how hot the van tyres were and the wheels, the road heat transfers from the tyre through to the rim. All the years over here worrying about slightly warm tyres!!!, over there i couldn't touch the damn things they were so hot!!!
You could always bring it up to the North West where although we have a hosepipe ban it has been raining and today is very cool !!!
For peace of mind jack up the wheel on the van and give it a spin, then ask someone to apply the handbrake on/off, see if its binding.
I know this may be an old chestnut, but one of the main causes of drums overheating is leaving the hand brake on while in storage. This can cause the brake pads to seize on. I always park the van, put the steadies down,chock the wheels with the clamp on,then release the hand brake.
I also do this on site if staying for more than a couple of days.
Sorry if I am stating the obvious
agree with the road heat theory, if the air temp is 25 degrees you can safely say road temp with be in the high 30's. last year when driving solo had left my car in the sun all day while marshalling, on the way home on the motorway I felt a really bad vibration, so off the motorway I came thinking soft tyre. 4 kicks later all tyres hard, so checked torque all okay. then out with the pressure guage, tyres were at over 40psi, the previous day in the cool they were at 30 all round. joys of air expanding in the heat and putting the pressures up. a slow drive back home followed as below 55 the car was okay above that and you could feel the vibration

Well you learn something new everyday! I'll tell my OH this when he gets home. Thanks.
Thank-you all for your advice. Just took van out for a 1/2 hour A road journey, and wheels just slightly warm like normal when I got back. Jacked the van up and wheels are freeley turning. The only thing I did notice was a very light rubbing noise for about half of one full spin on both wheels - is this normal for drumbrakes (no resistance, just noise). I spoke to the dealer earlier today, and they said they would be happy to check it over for me.
