All I would be selling is the pair of brackets. You have to set the spacers correctly to put the spot caliper in the middle of the rotor. The brackets are made to bolt in on top of the factory 3" bolt spacing. You use longer bolts, and put the park brake bracket on top of the caliper. The type of main caliper doesn't matter. |

So how much do you think the bracket is going to cost? It will come with an assortment of spacers I assume? Even if I have to file down to make it perfect, that is fine.
I like this idea a lot. |

It won't come with spacers. If I do this, it will be just the brackets. The spacers are from the local Ace Hardware store. The brackets are made from 6061-T6 aluminum, and the holes are tapped for M-8 x1.25 bolts.
I may just get the G-code files and put them here for anyone to grab. |

Hey Clay...
1:1 scale copies in a word or pdf file could be posted as well...not too hard to make that with hand tools if you don't mind working up a sweat (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) I should have my CNC mill running again in a few weeks if you can wait that long......(as long as I don't break anything else again...pretty sad, 2 CNC mills and both are broken (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) ) |

If they are that easily accessible (the spacers) then that's fine. Not sure where I could get the bracket made, but maybe Mueller will be up for the task? Please?

so we gave up on the idea of an inboard mounted brake? (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) iclays solution looks cool too.... adds sprung weight though... hmmm... what if you made the wilwood caliper mount on top of the rotor, so less bracket material is needed.... EDIT: Duh... like this (IMG:http://www.914world.com/bbs2/uploads/post-2-1107358864.jpg) |

EDIT2: also... who made the above one?
EDIT3: also...with clays solution, you need to remove the hub.... new bearings (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) |

I'm not gonna argue over a couple pounds of unsprung weight. I doubt I will ever notice it.
Mueller, that is cool, the important part is getting the bracket made. I don't care if we export it to the chinese, if it is going to still be reasonably priced, then I don't care who sells it or makes it. Of course it is Clay's design, so I rather him at least get something for it. |

The caliper mounts UNDER the rotor. That way you can hook the link up to the cable with the cable mounted in the original location. No custom cable, just a rod to connect to the caliper arm.
The bearing and calipers don't have to be removed, just the bolts that hold the caliper on. Then you replace them with grade-8 bolts that are longer. The park brake caliper bracket acts as a washer. The material is 1/2 thick 6061-t6 aluminum plate. |

okay. thanks clay. that looks like a winning solution (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) so what should we expect to pay for a set of brackets, and 2 wilwood calipers? do we need longer cables?

I am not going to supply the calipers. You have to find them from Wilwood.
As for the brackets, that would be up to the machinist. No, you don't have to put longer cables on it. Just a rod with a ball end to hook the factory cable to the caliper. |

Clay,
Another question came to mind. How does the amount of pull necessary to activate the spot caliper work with the travel of the stock 914 hand brake lever cable travel? Bet you never thought you'd generate so much interest after so much time.......Bet you wish you had a dozen sets of brackets already made up!! BTW, thanks for fielding so many questions. Andy P.S. Wilwood does not show the mechanical spot caliper on their Site. A quick phone call confirmed that they still stock them....Apparently when they originally removed them from their site, they got a bunch of calls, so they will re-post them soon. P/N 120-2280(P) for .81" rotor RH, and P/N 120-2281(P) for .81" rotor LH. |

Mike, That's the wrong one. The one in your link is the hydraulic one. You want the "MECHANICAL SPOT CALIPER." See above; the correct P/N is 120-22XX (XX depending on which width you choose). Andy |

When I had them hooked up on Betty's car, the handle did not move as much as the factory park brake. I put the pull on the inside hole to make it pull the longest distance. I was able to get it on the ratchet 2 notches. but that will depend on the cable adjustment on the car. More slack in the cable will let it pull farther up the ratchet. Personally, I don't want the park brake handle too high. I don't want to neuter myself getting in the car. I am going to contact my machinist about making a run of them. I will see how much he wants to do them. |

That looks intresting. I do have one question as far as parking brake.
For rear calipers without parking brakes why not just install a line lock solinoid in the rear line. Press foot brake, push line lock, release brake. Instant parking brake! (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) |

Two problems. 1. Most states (Texas is one) require a mechanical park brake to pass the state inspection statue. A line lock is not a mechanical park brake. 2. A line lock will bleed off pressure over time leaving your car rolling down the hill. |

Ahh I see,
1) Isn't a problem here 2) I suppose that might be a problem in "long term" parking, I was thinking of "short term" parking (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Carry on.... |
