Great information from you all! That confirms I have Bantam shoes. Yesterday I've sent a message to Draganfly asking if they deliver new shoes even if I can offer only those from a Bantam (they only deliver in exchange).

So do we have anyone with a C and a bantam that can compare the two to see the difference e.g. height, width,  linings etc.?

My stuff up,  took wheel off again today and there are steel caps just didnt see them, obvious that aluminium wouldnt last long against a steel cam, plus side is wear is dead even over both linings, apologies John, you pointed out , took time post photos, just rushing and not looking.

I just got message from Draganfly. They don't sell brake shoes in exchange if I send them Bantam shoes. Hm, I now need other sources for C11 front shoes. Any help is welcome.

Hi Thomas,
It might be worth asking "GP Motos Anciennes" on ebay,  They have a lot of NOS brake parts
I am pretty sure I do not have any spare. The wheel I took the photos of was an ebay purchase

Hi John,

I already called GP Motos. C11 shoes are out of stock but he wants to check again and will send an email. The same for British Only Austria. And no stock at Classic Motorcycle Spares. It seems as original shoes are not available anymore...  :-\

Anyway, thank you for your kind remark and cheers, Thomas

I got a message from Gary Parkin of GP Motos. He has found brake shoes which can make a pair. They are correct in the dimensions for the hub. The only problem is one is made from aluminum the other is zinc. He says that this will not affect any performance (zinc weights factor 2.6 of aluminum). He can reline these for €45 plus postage. I am not sure about the weight difference. Does somnebody have any experience with that?

Theoretically I cant see any reason why the weight of the shoe will make any difference, as it will not effect the force applied, contact area, or friction of linings.
May have slightly different heat dissipation values.....but hardly an issue on a C  :)

Heat dissipation for aluminum is twice as high as for zinc. But I agree, that shouldn't be a problem for a 'C'. The weight diffence might introduce a "hidden" problem but I too don't see it.

After looking around I decided to take the brake shoes from GP Motos Anciennes in France. They arrived yesterday and fit perfectly well. Today I took a test ride (no wet sumping after some weeks!). The front brake is now sufficient for a regular stop and for emergency both breaks do a great job considering the machine age. Thanks to all for their advice and help.
