Cooper Disk Brakes

Are the drive flanges for the 998 cooper disk brakes available?
If not (as I suspect), is it viable to modify the standard drum brake drive flange to suit the cooper disk brakes?
Or do I need to have mine repaired where the bearing has spun?

I agree Island Blue. Not a difficult modification either. Maybe someone ought to do a small run of them and corner the small market. Starting from good standard flanges is a LOT easier and financially productive than welding and grinding I'd say

Peter,
I have to say....it isn't all that simple ...I have made a few sets....very time consuming.......machine shops will charge a lot for this...if you could find one that will do it. However, if you have access to a friend who has a good lathe....that will be much more practical.
New mini flanges start around 30 pounds each....used ...seen some around 10 pounds.

There is a set on E Bay at the moment...bit rough on the face!

Sorry, much as I'd like to help.....I cannot make any right now....just too much on my plate at the moment.

GTS is right of course. You'd do these on a small lathe....., Myford super 7 size will do. It is straightforward turning during an enjoyable sunny afternoon, a bit of good music on and............

Off at a tangent............. If I had an old car to maintain and didn't have some reasonable facilities or an engineering background, the first thing that I'd do is to ask around and find a good retired model engineer in the locality. Not only can they make small scale steam trains and small scale Lancaster bomber engines. Given a pattern or sketch, they can turn their hands to anything.
