A Brake Has Locked On!

Recommended Posts

I have a 2007 Swift Charisma 590 twin Axle Caravan on an Alko chassis. Over the Easter weekend, we travelled about 400 miles (round trip), and stayed away for seven days. On our return we parked up on the drive close to the house as normal to empty the 'van and i then spent Sunday cleaning it up ready for the next outing. On Tuesday evening we hitched it up just to move it back onto our hardstanding and found that it wouldn't move because just one wheel brake was locked on.

 

We could acheive about one half revolution forwards and backwards but no more. The wheel locks up solidly. All of the others are free and working fine.

 

I have since removed the wheel and the Bowden Cable, (to ensure the handbrake is released). I then removed the drum retaining nut and I have tried to remove the drum without success. The drum will pull about 2-3mm but no further. I have tried altering the brake pad adjuster to its minimum and maximum (about 25 clicks total movement), but this has made no difference.

 

It feels like something is holding the drum in place. The drum will not turn beyond about 7mm by hand. I can see nothing out of the ordinary from behind the back plate and the bearing looks fine. I have tried tapping the drum off but something appears to be holding it very firmly in place. I don't want to hit it any harder for fear of damage.

 

Has anyone else any experience of this?

 

Incidentally - my dealer was very helpful and suggested that I deliver the van to them so that they could look at it in their workshop! I guess they were not listening to the first 90% of the conversation. .....

Seems to me that you have three options,

 

1. Force the drum of using some form of puller.( Will cause damage )

 

2. Arrange for a recovery unit to deliver the van to your dealer. ( Costly )

 

3. If dealer not to far away, remove wheel from offending drum and slowly tow to dealer.

 

If you choose No. 3 be prepared to be stopped by police, then explain that it has just happened and you are going to dealers, who knows, they may even give you an escort.

Thanks for your thoughts. ....

 

Option 3 seems the most appropriate given that the dealer has a sister company about 5 miles away. I must admit I have reservations about towing with a wheel removed. I guess that I should pump up the the tyre on the other wheel to compensate a little and then take it slowly!

 

Cheers

Does your dealer have a mobile fitter who could come to you?

Try a few hard knocks with a Birmingham screwdriver it may free it, I doubt that you will damage the drum.

With a 2007 'van, it should still be under warranty, in which case the dealer should come and sort it out surely.

Yes they have a mobile service facility but they are unable to call out for a number of (unspecified) days ahead. I got the impression their man is on holiday. They also talked about call out charges. The 'van is currently occupying the path/driveway to our back door which is a bit awkward. ....

I started with a standard size hammer and progressed to a bigger one after that failed. .. The problem is that it is not possible to get a good swing on anything too big!

Hi Jon

 

Option 3 probably isn't a good idea as I doubt a single tyre can take the weight on the one side.

Have a look at the load index against the van weight to check for sure.

Maybe a re-post into the Swift section will elicit a response from Ash? Or a PM to Swift with a link to this thread may give a solution.

I had this once with a Lunar at the national rally (CC)

 

I ended up dragging the caravan onto a tarmac road and reversing the unit and then pulling it forward again several times. The brake finally let go and all was well. The next service revealed no problms and the engineer said the shoes had probably 'stuck' to the drum (I had left the handbrake on).

 

If you are able to get your car onto the hitch and try this it may be worth a go before panicking too much :unsure:

I tried this - we learnt of the problem after we pulled it forward. (The van had been reversed into place). We then tried reversing and pulling forward again several times but with no success - it seemed to be that every time we moved, it took less time to lock up i. e. we had less movement available each time.

 

I have just been chatting to an ex vehicle for mechanic about it. Hi comment was that if we had towed it recently for a few hundred miles, brake dust may have built up and then turned to a 'glue' when it was stood for a couple of days after. I had washed the van and wheels down so it could have become damp.

 

His suggestion was to hit the drum a considerable number of times to break the bond formed between the pads and drum surface. I am going to try this later today.

Thanks for your advice. I have just spoken to a dealer about this and they strongly recommend against it. I suggested stripping all weight out of the van beforehand but all sorts of issues arise including invalid insurance. They suggested Green Flag or AA Recovery but because the 'van is at home I'm not covered with my AA membership. (I'm not a Green Flag member).

I have been told that I am hitting it in the wrong place! A mechanic has suggested that I hit the side of the drum to free the 'glue' that may have formed. This would be followed by using a vey large hammer behind it. ....

 

I will let you know how I get on!

Have you tried to tap on one side of the drum, while having a large flat bladed screwdriver on the other side wedged in between the drum and back plate and use as a lever to ease the drum off, used to do that years ago when i was a mechanic.

Hi Guys

 

Many thanks for all of the responses, ideas and thoughts. I have fixed it today - I was astounded at what I found!

 

I used the services of CaraTec who are a mobile servicing and repair business and are based in Tewkesbury. (07838 145647). We ended up using an axle puller to remove the drum. We used a couple of wheel bolts to provide the purchase needed and fiddled with it until we could get a strong pull.

 

Once we had removed it we found a very rusty drum interior and the drum pads had welded themselves to the drum surface to the extent that we could see exactly where the friction pads had been up against the surface of the drum. The wheel bearing had also been running hot because we found some grease had leached out. Not too badly but it was there. ...

 

The stub axle was also a bit more rusty than I would have expected on a two year old 'van. Other than that no broken or damaged components were found and pad wear was reasonable too.

 

The only thing we can think that caused this problem was that we parked the van with the handbrake on while it was being cleaned (six days), and the damp somehow caused the rust?

 

 

All I have to do now is refit the wheel and re-adjust the brakes.

 

I will post some images from pictures that I took onto the gallery as I have not yet worked out how I can add them within a topic directly.

 

Note: Please go to the gallery where I have now posted some images of the drum and stub axle from the offending wheel.

hi,it sounds like one of the brake shoe retaining clips has gone awol, i had this many a time on cars that have rear drums,best way i found is too have two leavers either side of the drum and base plate,apply gentle pressure and have a assistant to tap the drum with a rubber mallet,i dont know if caravan drums are similar to cars but the might have two threaded holes in the drums which you can screw bolts into to act as a puller.

 

 

note to self,read all posts before adding a reply
