Almost done! I wish I could say it was done...
Story to date: Months ago I went against very good advice and purchased as second hand set of Cooper S discs and have been buying replacement parts since then

If you are considering this, my advice is DON'T! Just buy a new set! cost so far has only been a few $100 off buying a brand new set...
Fast forward to last weekend, Dr Mini helped me rebuild the calipers with new kits, new pistons, new seals. Back brake cylinders changed to S ones, new brake lines at the back, hubs have new bearings, 4 new ball joints, brand new CVs, boots, etc.
This weekend I dismantled everything, changed the left brake hose which was a piece of cake, but the right hand one was challenging to say the least!

What a crappy place to put the brake hose bolt! Why have a hole cut on the left hand side but not the right? So needless to say I "redesigned" a new hole in the right hand gaurd to get to the bolt and brake switch. Even then it was a bugger so I had to remove the matic heater as well.
Anyway all in the past now, new lines are in, calipers bolted on. Then I found that the Karcraft disc pad split pins were WAY too big! These are the right pins but the tolerances were way off!

So about 20 mins on the bench grinder later, they fit into the holes

Make sure you buy the right ones!!!
Whole system bled, pedal feels good but I think there is still air in there as the system ran dry due to the awkwardness of the right hand hose

might have to do the backs again too as I don't think I did a very good job when I replaced the back hoses.
Kev had to also "remodel" the calipers so that they would clear the LS contessas. Only 1-2mm off each bleed nipple lug. The left hand one was a perfect match however the right hand one still touched, but only just...
So tonight I will angle grind away 1/2mm to get it clear off the wheel and then all that's left is wheel alignment. Then I will have a "sleeper" Mini K! no flares! yeah baby
