Anybody done it? If so how, and if not, any ideas what sort of scrapyard tat I'm going to need? The lever and cables are easy enough, but how would you go about converting the rear drums and shoes? It doesn't need to be mot legal or even stay on (only thinking it needs to be a fly-off style) as I'll keep the stock one on the front. |

this is a good resource once you click something that looks ok there is a list of other vehicles its fitted to -http://www.apecbraking.co.uk/catalogue im guessing you just need to make a drop lever from the top of the rear shoe and a fixed or adjustable by thread bridge between top of lever near pivot to opposite shoe weld in a piece of tube as cable giude/stop for the cable outer |

Yeah I guess you're right, I'm sitting here just thinking about it but I really need to have a good look at a rear brake shoe set up and see how I could adapt it with some simple to make steel bits and pieces, levers and cranks etc. I wonder I'd simply operating on one shoe would be enough to lock up the wheel? Or would I have to operate both? Would it be easier to plumb in a second master cylinder and do it hydraulically, or would you bugger the rear cylinders up by using huge force on them? |

usual rear brake is simply a lever and a bar that bridges the lever on the rear shoe to the front shoe its a very simple and easily fabricated device to a man of your skills I just wish i could find an easy diagram of the set up - you must be familiar with rear drums on Minis? look at American how tos on tinternet as usual their cars are agricultural and simple |

Noooo, Hydraulic would be much easier, rally cars use them all the time. Google image 'Hydraulic handbrake' https://www.google.co.uk/search?q=hydra ... 52&bih=877, only issue would be finding a master cylinder with LHM seals. |

What would be wrong with using a standard 2cv master cylinder? And how would one plumb it in so it works with the normal rear foot brake system? |

Basically, I can make a lever which operates a standard 2cv master cylinder, I can run brake pipes from that to *somewhere* at the back, but where do I splice into the rear brake pipes? And when I get all excited and wang on the new skid lever, what makes the brake fluid go backwards to the wheel cylinders and not forwards to the normal master cylinder, fucking it right up? |

Need a one way valve |

Surely a one-way valve in a brake system would mean the brakes would just be locked on after one application? |

I've done most of a bottle of Rioja, by the way. |
