Post subject:  Cooper S Brakes conversion from drums
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! :shock: 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! :cry: So about 20 mins on the bench grinder later, they fit into the holes :roll: 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 :twisted: :P Group Nb racer spec :lol:

Some pics tonight.

These calipers fit so close in there.. :shock:
No room for stick-on weights, even in the middle!
Inner ones need to be clip on and `ping' off style. :lol:

With the brand new calipers I bought, there was no way they were going to clear on LS contessa's. I thought of spacers and even then, I don't think so.

Congrats Chong, almost done. You must be hanging out to drive Lillee again.

Logic suggests that you have done better than you would have by just buying a new set of brakes

You appear to not only have "now new" S brakes, but also hoses all round, Plus uprated back cylinders, Plus new lines, Plus new wheel bearings, Plus 4 new ball joints, Plus new CV's, Plus boots.

Take off the price of all the things you have there [that you would not get with a new set of brakes alone], and I think you'll find youv'e done quite well. You have as new brakes plus all the rest.

Nice feeling, knowing you have stoppers that work.
Cheers Dat

Yeah I am pretty happy with it all. Took her for a drive last night around the block and there is definately air in the back system. Other than a spongy feeling brake pedal she does stop much better. Stops straight which is more important! and stops over and over again which really what makes it worth the while! :lol:

New everything Jimbo... Ball joint kits come with new rubber dust caps. I even selected out of a collection of grease nipples the tightest, least worn nipples. About the only things second hand are the hubs themselves, the calipers, the drive flanges and discs.

I will bleed them properly tonight and align the wheels and we are good to go! :D

Yeah *cough* *cough* they stop great *cough* :lol:

Here is a surprise, the wheel alignment is still correct! :shock: :shock: 1/16 toe out, I measured it twice to make sure I wasn't seeing things but it's true... anyway St George Steering will tell me if it is really correct or not 8)

Bleed the brakes back then front, lots of pedal now :D

My mate has a pair of those plastic extentions for the 'bean can' MC... He didn't end up using them on his Nb car, so i'll give him a call and see if he wants to offload them for a small fee. :wink:
