Rear Discs

Apart from the KAD rear disc conversions does any one know of other companies who do a kit?
Or has anyone made their own rear disc conversion?
Thanks

I personaly would use something like the Sierra Cosworth 2wheel drive rear calipers which have the cable hand brake built in. This along with th Cooper 7" disk (not the Cooper S 7.5 disk) on the original hubs with a one inch spacer. The other option to the original rear hubs is to have one machined to the requirements best suited to the fittment of these cooper disks. Go too big on the disk and you will over brake the rear and lock it up.Even with the smaller disks an adjustable bias valve would need to be fitted to get it set up properly using the brake efficiency tester down at the local friendly MOT station :cheese:
The only real reasons anyone should be concidering disks on the rear is, A) for the looks. And, B) thier simplicity in servicing. I.E. no need to adjust. The reason for this is that the drums, particularly the Minifin veriety are more than adequet.
To top this off, after I get the disk set up working I will look at the ultimate in braking power - ABS :saywhat: Stop on a sixpence ( how many people on here know what a sixpence looks like :gasp: ) LOL

Dont see why not. If they got a mechanical hand brake built into the hydralic caliper and use sollid disks there should be no problem, its just a matter of phisical size and rear items are normaly smaller. The Sierra Cosworth 2wd items are non vented so ideal :cheese:could you use citroen BX front disks as they have a front hand brake ? :erm:

obviously removing the cabe operated item and fitting a hydralic one.
The handbrake MUST be cable operated.

He believes it does not, as long as there is a seperate hydralic circuit that operates each system so if one fails the other can still remain orerational.obviously removing the cabe operated item and fitting a hydralic one.
The handbrake MUST be cable operated.
Plumbing the handbrake into the main brake circuit is a no no
And note that this was not my idea and in no way would i concider it anyway

I do agree with that though, until its proven.

You mind me asking what you need rear disks for?

out of intrest, which manufacturers are fitting hydraulic handbrakes to their cars?...any links or evidence?Hydralic handbrakes seem to be like LED rear lights, once they were illegal now all top fanafactures are doing them. Just because they didnt pass some stupid law some time ago, as they werent tested, doesnt mean they arnt any good and now they are. Hydralic, I think, is more reliable that a piece of cable any day as long as they are of a good quality.

No not at all!!You mind me asking what you need rear disks for?
I use my mini for tarmac rallying and have a 1600cc Vtec fitted in it.
I have metro 4 pots with mintex 1144 pads. I've binned the standard bulkhead bias valve thingy. and now have a hydraulic hand brake with a wilwood in line bias valve. I have a smaller then standard bore wheel cylinders.
They are fine for road use but on stage they get some serious abuse and the standard drums get hot and i end up with bad brake fade! so it gets a bit hairy!!!
I've got some KAD 6 pot calipers to put on over the winter so need to sort the rear brakes out.
However i dont want to spend £100 on some minifins, i'd rather put it towards a rear disc conversion.

As I said with the KADs, they told me that they developed the kit more for weight loss than improved braking performance. However I told them my mini will be used for road/track days, not sure what they would say if you told them you use yours for racing.
I should imagine using their 6 pots and some of their minifins on the back would be sufficient!
What size wheels you use?
