Hi all i was looking through my garage when i stumbled across some mini brakes. years ago i, well my dad converted my 1986 mini city to 10 inch wheels from the standard 12inch using a kit he has told me that the discs (vented) and cailpers (4 pot) are from the metro turbo not sure anything else but they fitted quite easily Attached File  mini barkes 001.jpg   77.17K   47 downloadsAttached File  mini barkes 002.jpg   66.41K   19 downloads

You can't use Metro 4-Pots with 10's, they simply won't fit unless you have a offset so large that the disc and calliper are next to the wheel rather than in the barrel.

Metro 4-Pots are still popular for people who use 12" and above wheels.

Hope that helps, Noah.

The disks don't look 8.4", have they been turned down and the bolt holes on the caliper moved?

Are you sure they're not 7.9" 4-Pots with turned down discs? Minisport sell ally ones now.

from what my dad said an engineering company did a kit the would just fit on with no other mods i do recall that a lot was modified and the discs do look smaller it really is a nice set up iam getting rid of a lot of mini stuff so i was going to sell them but not knowing much about them has led me on the forums

They're deffinately metro 4 pots, my guess is that the mounting holes have been moved as the top of the calliper appears to be untouched, have you measured the size of the disk? Also have you got any more pictures showing the mounting holes? I've got a pair of 4 pots I wouldn't mind having a go at doing this with.

It can be done, usually the mounting holes changed, as per the pics....

Metro 4-pots with the mounting holes re-located and the discs turned down to 7.9"

Jim at R.A.C.E. has done a good few sets of these - the name you might be trying to remember could be Race Engineering which is what quite a lot of people refer to them as. He would send them anywhere but if you can remember whereabouts in the country they came from it might narrow it down - R.A.C.E. is in Withnell near Chorley, Lancashire.

I made myself some brakes the same as these a few years ago, had the discs machined to 7.9", and redrilled the holes (had to machine the inside of the calliper a little as well) all worked fine! If there priced right, these will be an excellent brake set up for a decently powerfull mini wanting 10" wheels :)
