Post subject: | Brake Conversion - Use 8.4 Disc & Calipers |
Ok, I've read lots into all the brake conversions, but what about using stock 8.4 discs and 4pot calipers (KAD or something) or even standard calipers. Would the same still apply, a special braket and spacers?? Your thoughts? |

The KAD calipers would bolt straight onto Mini disc hubs, as far as I know. |

I realise that, thats why I want to know if its possible with a simple adapter plate (ie. to use drum uprights) as in the other conversions. The whole point is to avoid the $350+ cost of each disc upright, and instead use common mini parts including the drum uprights I already have. |

I would recommend using disc hubs. |

A spacer on a drum hub would have to be so thin to fit between the hub and disc that it wouldn't hold up the caliper! ![]() |

What he said.... ^^^ And don't even think about welding a lug onto the drum upright. Apart from being illegal, the swivel hubs are a grade of cast iron, which does NOT like bits being welded on. How do I know this? I have machined swivel hubs inside to fix `em when worn, as a machinist I know what cast iron turns like. ![]() |

Thanks guys, I knew not to weld cast iron (although I did weld a small hole, breather??, in a 1-1/2 SU manifold). So how do these other conversions work then? Is there more offset on the disc to allow a bigger spacer to fit between hub and caliper? |

What he said...^^ They are shallower because they use single piston sliding calipers, which stick outwards less. ![]() So, there is room for a mounting bracket to bolt onto the outer face of the swivel hub. For a Honda setup they are about 7mm thick. |
