This is going to be a long post...
I'm assembling a mini I bought that was pretty much fully disassembled when purchased.
I'm currently rebuilding the front subframe.
It had 12" wheels and 8.4" rotors.
I'm going back to 10" wheels and 7.5" brakes.
I bought a ' 8.4" to 7.5" conversion kit from Minisport, like this:
https://minisport.com.au/mini-brake-con ... s-calipersI discovered the the front hubs were probably from a Metro when I realised the ball joints were the sealed, screw in type.
The ball joints presented no problem, but the 7.5" rotors are giving me some grief.
Firstly, the bare hubs didn't fit into the back of the rotors as they did not have this shoulder:

I quickly fixed that in my lathe and eliminated that problem.
I now have an issue where the rotor is interfering with the hub before the bearing is correctly tightened/preloaded.

How much clearance is typically seen where I have the arrow?
I guess I'll have to fit the caliper and possibly make a spacer for the rear bearing to centre the caliper on the rotor.....
Just thinking out aloud, more measuring and investigation required...
Has anyone else struck this problem? Am I meant to be using different wheel bearings or other bits with these oddball hubs?
THANKS!
