    No, I was just getting a link, My last post was meant to say, One year only 72 og backplate had no retainer holes and no retainer springs, I am off to find a link.But you are right in theory they should flap about. People have modified 72 brakes with new backplates. :thumbsup:

    The first pic shows how they were, the bit in the bottom left corner show how they are modified. alledgedly, I have the first pic set up on mine still.

    The wheels sound like the don't fit and have bent the drum. The fixing face of the drum is only about 3mm thick. Something up with the wheels.
     
  7. all those retaining pins seem to do is stop the shoes from pulling out at the same time, when you're removing the drum....the shoes themselves are self-centring, provided the ends aren't stuck with crap in the piston slots....

    Smells to high heaven....I'm told that the former CEO was buying back stock at the liquidation auction.....and on the website it states they are 'restructuring'.

    Fiver says 'production' will go offshore with the same management team that wound them into administration.

    Still, so long as all the creditors were paid off, and the 24 staff weren't skanked out of their redundancy then that's fine. Of course, that might not have happened - it's up to each of use to make up our own minds eh....
     
  9. Few issues here.
    1. Im not aware that the drum bolts have to be removed. - I didnt on mine.
    2. Drums have studs and not bolts - Im using the standard ones and theres enough thread to accomodate them
    3. Mines got 1 year only shoes (73, manufactured late 72) and its hot the springs and clips on the shoes.

    Just a guess but if the drum bolts have been removed and the wheels tightnede eccentrically then the this may have resulted in the drums being "skewed" and as a result touching the shoes. Take a wheel off and look!
     
  10. Knowing it's now studs not bolts, I retract my previous assessment, I would suggest the wheels had been bolted on without removing the drum holding bolt or lining it up with the recess in the wheel (if there is one), this has distorted the drum.
     
  11. Well you live and learn....glad I couldn't afford them at the time....but there were some skills lost there.....Shame:(
     
  12. turncoat....:D

    Basically the one year only thing is a bit misleading from what I can gather. it kinda spread over from late 71 until some time in 72, Mine has no clips, some have clips. people have told me they had no clips but modified theirs to have clips. confused? I am!
     
  14. various retailers say on their site that the empi 5s need longer studs....maybe this is just a ruse to get punters to buy longer studs and bolts to match at the same time....just more aftermarket b*llocks....who knows?

    They recommend a certain amount of thread I can't remember exactly but 13 lines of thread springs to mind.

    Erm...what width tyres are fitted? Might they be fouling something...the spacers would move the wheel/tyre away from the swingarm etc....

  19. ....and according to rob and dave's aircooled page on the very subject, he says empi 5s need 14mm x 1/2 an inch ffs....maybe you can get long nuts with short studs and short studs with long bolts and maybe one empi copy varies from another.....:D

    New back plates don't have holes for the springs as they became obsolete. Perhaps you backing plates had been previously replaced poppy.
