Brake drum refurbishing

  1. I have a Reliant Fox camper in for restoration. I am in the middle of replacing all of the brake components only to find that the drums are NLA. The originals are quite worn and not really fit for re-use. At one time every town had an engineering shop that could deal with it, but all my searches today have come up with nothing significant.

    Are there any recommendations? May be more than just a skim required.

    Would drums off any other car or van fit ? Or were they specific to reliant ?

    If it’s an obsolete unobtainable part it may be worth making up a disc brake conversion , can’t be the only reliant that needs future proofing. The problem with a savage drum skim is the shoes end up the wrong diameter for the drum and only make contact on the drum in a small area.

  5. The front drums are unique to this model. I would say that they need metal spraying and then skimming to size. Just a skim will be insufficient due to the wear.

  6. That is why I want them refurbished, not skimmed. There are cost restraints on this one plus liability issues, so has to be standard.

    I have skimmed loads of car and lorry drums on a lathe (four jaw chuck).

    With no problems at all.

    How bad are the drums??????????????

    Most brake shoe remanufactures will take in to account skimmed drums and supply shoes with a more pad increasing the dia

  13. Pretty bad, enough to have to force them off even with the shoes fully retracted.
     
  14. Fronts are unique to the fox, although backplates are generally Mini.

    Loved doing the kingpin on them when we had to account for every minute during a working day ,with the right tools about a 35 minute job ,can’t remember how long was allowed for the job but certainly made up lost time . Adjusting the doors on them after they had been caught by the wind was another, had a piece of 2x2 suitably modified , a two minute job. Never had to work on a Fox so can’t help with the drums but if the used Mini backplates and the same PCD I would look at Mini drums modifying if necessary? Some of the old brake part catalogues showed all of the dimensions, might be worth asking at your local motor factors ? Past Parts in Bury St Edmonds might be worth a call?

    I understand the cost restraints and trying to keep within the customers budget, but............ I would still sooner put my name to a well executed conversion that will work 100% and have spares availability than relife an antiquated brake drum that was made when god was a boy. The bigger liability will be with the lashup thats on there.
