converting rear brake drums to disks??
Turbo Mini Forums

hello all

i would really like to convert the drums to disc brakes at the back, since im upgrading the front to 4 pot's i would like to use the old front discs and calipers. does anyone have any idea of whats involved in this? has anyone done it before? is there a guide? i tried the search botton but didnt find anything on the topic.

all help is apreciated.

thanks in advance.

No-one has done thos before and for a very good reason. The conversion would weigh more than the drum and all the added braking ability would be useless. You only need 30% of the braking force on the rear (well maybe upto 40%, but anymore and braking would be unstable).

Look at the KAD kit available for the sort of size that is needed.

I'd suggest if you are going to all the effort, some kind of scooter conversion would be best.

Sounds like a pain in the tits to be honest. You would need some form of mechanical brake aswell. As above, alot of work for no gain (except weight). Just buy KAD. If you really want rear discs I suppose you might be able to use VAG rear calipers with the winding pistons for the mechanical brake. It would still take alot of work though

yep its the handbrake thats the difficult bit (not that te rest isnt!) although aparently on a pre 68 car you dont have to have a handbrake.

hi

thanks all for the replies, i always thought that disks at the back would improve the breaking by a lot., i really dont see how it would be unstable...
as for weight, im not to fussed about that...

where can i find this kad conversion? is it worth th cash?

the thing is mate, the mini is quite light on the back end. especially when made lighter, most of the weight tends to come off the back.

this means that it makes it easy to lock up the back end under heavy braking. a well set-up pair of drums will do this with too much bias towards the back, its not fun.

you might aswell yank the handbrake up on a high speed corner entry.....then try to control it.

google search is nearly as good as TM search

I have to use a limiter on the rear of my car having 6 pots on the front and alloy drums and std linings - so don't waste your money!

I stand corrected. You should know

Don't get confused into thinking that drums are rubbish either. They generally can out perform a disk in pure stopping power, unfortunately they can't get rid of the heat so degrade quickly.

The only reason you would put drums on the read, IMO, is to save weight, not for better braking.
