is it worth making new disc's?
Turbo Mini Forums

hey, another stupid mistake that im trying to fix. Ok, when i decided to turbo my car i went to a mechanic to find out if he could engineer the car, he said it was fine as long as i had a disc break front end, my uncle sold me a 7inch disc break set up for $100, i then spent $600 reapiring them and a further $400 for a 7inch booster, the same day i got and install'd all these parts i found out how useless they were, mainly because of the thickness (mine are down to 4mm after machining) and design of the disc's and hub's (bad heat transfer causes break fade), so now im thinking of making my own disc's with hub's out of a different (better) material, to origional thickness, with groove's machined in both side's to improve breaking, it wont cost me much appart from time and i can make them very accurate........but i dont wana make the same mistake as my inlet idea and find out there is an easier and cheaper way, can you's help me out with some advice?

Thanks. Chris

i think you should forget all about making your disks. I think you may end up in hospital as a result. Disks are made from some pretty high spec cast iron. Anybody wanting fancy disks really needs to talk to a good knowledgeable AP dealer or similar brake manufacturer.

Yea, the blokes that work next door to me are ABS breaks, they specialise in rally breaks and put me on to a metal call'd Spheroidal Gruphite, its a type of cast iron they use for breaks and i'v been told it can be machined.

Oh yeah machining it is no problem, its quite nice to work with.

Just have to make sure you get the correct material to work with. Just didn't want to see anybody trying to make some from some mild steel or something !! lol

If you want to upgrade you can retain your swivel hubs. Remove the caliber, disc and drive flange as well as CV joint. The swivel hub and wheel bearings will fit any Mini disc brake setup. Instead of Cooper S stuff you can use 12" flange/dics and machine them down. If you fit another make caliber you may need to shim the caliber to hub accordingly. I would sell the 7" Cooper stuff to a restorer, no really worth anything in hi po use. Personally I don?t like mix and match, it is so much more hassle when you need to replace something.

mirage:mild steel breaks, i wonder how that would go? lol

jukka: i was thinking about that the other night(even though i wosnt sure if the discs/hubs had sam bearing size's ect.) but i am realy keen on the idea of grooved disc's, i recon it looks cool aswell as inproves breaking a heep and you cant machine that sort of detail into a standard disc, the cast iron just isnt strong enough (thats what i was told anyway) please correct me if im rong as im completely new to mini's

thanks a stack
