question Explorer Brakes

[daz76]

My Scammell Explorer was off the road when I bought it and has never really had brakes. The rebuild has progressed to the stage where I will soon be taking the hubs off to see what lurks behind. I am learning as I go along, but I seem to recall that older vehicles with lower pressure to the brakes need 'softer' linings which are not readily available. Can anyone advise if this is the case and if so, where to get them please? Thanks Daz:confused: Any useful tips about what to look out for would also be appreciated.

Hi Daz ! Have you got lots of exposed thread on the rear brake adjusters as this would indicate your linings could be worn out ! When I removed my hubs recently I was pleasantly surprised as the linings where in very good condition considering Daisy had been used as a HGV recovery lorry since being demobbed ! Just required a clean up and adjustment and hopefully they'll see me out now she is a Lorry of Leisure ! :-D Good luck and Merry Christmas !:-D

Thanks Andy-Yep there is quite abit of exposed thread, but I'm not thinking the worst til I get the hubs off! This can wait til the warmer weather as she's outside. Brr! Happy christmas to you too. All the best. Daz

I have been told that the limit is about four inches of exposed thread, otherwise the pivots are beyond their working range, mine are getting near to it. I have also been told that when you get to the four inch limit there is still pleanty of lining left and a spacer can be inserted to give a second life. This may be apocryphyl, I would be interested to know.

I suspect you are thinking of the problem that happens when new non asbestos linings are used in old type brake drums.

There were many problems with early non-asbestos brake and clutch linings. These included poor friction and rapid wear, often resulting from intolerance of high temperatures for some woven materials, cracking of certain moulded linings and high abrasion leading to rapid wear on discs and drums with some pads and moulded linings. Moulded linings have also been prone to require extensive bedding in. It has not helped that some relining companies appear to have often fitted non-asbestos materials that are completely unsuited to the braking system of the particular vehicle, for example, using abrasive materials for vehicles with steel drums or fitting low friction moulded bonding material, intended for the rear brakes of cars with servos, or to pre-war motorcycle shoes. We have encountered, and rectified, many problems of this kind in recent years and now routinely advise owners of old vehicles who find their brakes are much worse after a reline that the problem is almost certainly due to the wrong material having been fitted.

 

 

 

Nevertheless, the more serious initial problems with non-asbestos materials have been largely overcome and in recent years we have been able to use good quality high friction moulded and woven materials for relining and remanufacture of linings. In fact, the non-asbestos woven materials generally have a higher friction value than recent asbestos based materials, withstand similar or higher temperatures, form to radius more satisfactorily and tend to be better in appearance overall. For clutches for older vehicles, we have supplied very satisfactory non-asbestos linings for many years.

Thanks Croc. I'll let you know how I get on, but it won't be for a while yet. Just trying to get info together first. Cheers and Happy Christmas. Daz

[daz76]

That pretty much answers my question Gritineye! So any good re-manufacturer should be able to get the right lining material IF I need it. Where did you get this info? Daz

Glad that helped, found it here

This chap will do them suitable for old drums.
