Rear disc onversion
Turbo Mini Forums

hi all had anybody done a rear disc conversion before using fiesta calipers I know its a popular upgrade 4 10 inch wheels at the front but Im using 13s but would like 2 know if its possible at the rear and if so whatt parts will I need 4 the conversion tha ks kezz

is it really needed? a decent set of four pots up front, the right pads, drums with quality shoes on the back, all in good condition and adjusted properly serves most well

to big and heavy

Thats true i jjust I would like 2know if it possible and the parts I need as if I can do the conversion I might as well do it as im going ott on the whole car

going into tree backwards is also ott

I would like to see a light weight pair of drum back plates. Pretty much everything else hanging from my rear subframe is ALU, so short of turning all the fins of the drums I can't see many other places to loose more weight.

Oh im not t doing it 4 weight reason ttbhif I was going dwn that route I might as well sell the mini and start from scratch and go and buy carbon fibre parts ali rverthing and so on but any way I just like 2 know if anyone done it can can dhow me a pic ofIit if poss

KAD do a conversion kit As does Force Racing - http://www.force-racing.co.uk/rear-suspension/

No, nobody has done what you are saying therefore nobody knows exactly what will be needed.

If you did it you would most likely have the car swapping ends every time you braked.

Rear disks are only worth it if youre going for weight loss, if youre doing it for looks then dont bother - Fiesta brakes will look pants

I seriously doubt it!

A well set up/thought out rear drum brake set up is more than adequate and in some cases can lock up before the fronts. So other than weight loss, there is no real benefit to a rear disk set up unless you have gone for some exotic custom rear suspension.

I spied a post on another forum in the last day or so from a guy in the states who has done gis own rea disc conversion with vw parts. The idea would need to be developed a bit more though

I would think based on the kad unitsva decent bikecaliper setup would work well

Ive seen on another forum somebody was using fiat punto turbo rear calipers, looked a tidy setup. Ill have to find it again to see how its going as i fancied having a go at it too

If you are going to do rear calipers you are much better using proper rear calipers so that they include a handbrake. Using fiesta calipers is just a daft idea. Which is probably the reason why nobody has done it.

A man without a project is like a like a woman without a shopping list.

There's a couple guys over here in S.A. that have done 4 way disks using the golf2/3 setup which allows for the use of the handbrake on the rear. Personally I'd say it's a fair bit overkill for a mini. KAD or Force are the best for the job and aesthetics.

Life is always a matter of opinion and quite frankly, no ones opinion really matters.

a pair of motor bike calipers would be a good swap and light think fiesta brakes would be pointless you spend more time trying to get it to work propily than going with a kit thats been tried and tested

I made the mistake of fitting rear discs and wilwood calipers on my Toyota 16v powered mk1. First track day ended up swapping ends a few times. Eventually using an adjustable bias adjuster to reduce the braking force at the rear the car became more manageable under braking. This is the only picture I can find of the conversion

If you look at few of the race cars (bill richards iirc is one) at one point did not run any back brakes, simply have massive brakes at the front

Willwood do a caliper that has a handbrake on, much better as a starting point.

As above, a bit pointless, but if you get a disk of a small light car, those small citroens for example, AND you put in some adjustable bias, you might just get away with it.

i agree, only use disks all round if your going the full ultra light beam + swing arms coil over and all that get up
my mini has 8.4" vented 4 piston aluminum calipers i have never had any problems pulling it up aside from a few lock ups caused by being silly...

only reason i can think of is you may get a firmer pedal from all 4 wheels being disks as there is next to zero spring/liner travel to take up before the liners touch the drums but this is solved by regular adjustments (or in my case new rea drums that run true as mine are slightly cooked) anyway they will do for now makes adjustments a bitch!

If your going "OTT" buy the KAD ones?
