It is difficult to be specific as one inspector may view the manual wording differently to another, the words lock wire are used as an example in the text from the manual I put up so below is a selection of lock wire options taken from my aviation days.  |

If I remember right are the nuts not drilled through two corners offset from the centre line rather than through the centre line? Hard to explain but the hole passes ONLY through the nut so preventing the need to drill the shaft.
I thought it needed at least two nuts in the same plane in order to work though, on the lock bar there is only one nut each side which would give nothing to wire to.

My IVA inspector wanted the wire through the nut and threaded bar, then looped around somthing that was fixed like the pedal box itself so the shaft could not be turned. He said wire through nut and threaded bar only was no good as you could still turn the whole thing inlcuding wire.

Locking 2 extra nuts against each other and then lock wiring them together by drilling the corners of the nuts should remedy the balance bar "inoperable by mechanical means". Provided you wire them to a fixed point i.e not the bar itself. Drilling a hardened brake balance shaft is something to avoid. IMO. They used to ask for them to be welded until it was pointed out that this may change the structure of the material.

Piping up the brakesThis is going to be picture-heavy.. First up, all my Venhill Powerhose plus bits all lined up. Spot the mistake?   Hey, that's not yellow!  Venhill don't sell a T piece for the 6mm ID low-pressure fluid hose, so I popped into Woodies and got this brass gas fitting instead.  All lubed up with a few dabs of this.  So pretty! I'm trying to forget that the washers omitted from my Venhill order, in this picture, were bought locally at robbing-backstard murraymotorsports.com for an eye-watering €16.69.   All my ducks in a row

Starting with the good news, my Powerhose plus lengths were just right; rear calipers to rear T 125cm each, rear T to rear Master cylinder 225cm. Front calipers to front T 100cm each, T to front MC 60cm. Lovely. The brake-fluid proof 6mm ID tubing was cut with a stanley knife (box cutters), pushed over the T and brake fluid reservoir with lots of brake fluid to lubricate, and held in place with some nice brake hose clips form Venhill. Of course, it couldn't all go smoothly. First, anyone following my build will note they're not yellow as ordered >:-| Venhill, to be fair offered to remake them for free for me, but I couldn't hack the 10 day wait, so I'm going to learn to love the clear. They have a certain industrial look that's good, you can see the braiding, which is cool. The 7/16" banjos for the MC inlets are also stainless steel where everything else is chromed, so not only are they more expensive, but they look duller. Minor annoyance. Venhill only sell 10mm deep banjo bolts, so the focus rears are going to have a shorter 'stem' than the donor flexi (left). Venhill said this'd be grand, anyone say otherwise?  The next bit is entirely my fault though. When ordering the banjo bolts for the low-pressure side, I didn't pay attention to the number of threads, I concede when I read 7/16-20 on the Wilwood spec page, I assumed 20 was the 20mm depth/length of the banjo. So my 24 thread per inch (tpi) banjos won't go. In a brief moment of madness I considered both forcing them in, and tapping both the MC and the banjo to an acceptable metric thread. Instead, I'll send some stuff back to Venhill and wait it out.  While I'm at it, I'll probably send back the SS straight banjos and get some chrome 90 degree ones instead, much nicer. Plus an extra banjo + bolt for the clutch low-pressure end. Update: Venhill don't sell 20tpi banjo bolts, so that's a pain. Going to send back all the low-pressure stuff and get it from somewhere else. Not going to match, which is mildly annoying. So, with all that, my brake lines are far less complete than I'd hoped, but at least the low-pressure part is mostly done.  |

Low pressure sideHaving ordered the wrong banjo bolts from Venhill, I found they don't actually sell the right ones (20tpi) anyway, so I sent that stuff back and ordered 3 each of - 7/16"-20 (AN-4) SS banjo bolt, plus 2 washers.
- M12 SS banjo, 6mm push-fit tail end
Oddly, according to the very helpful person I spoke to on the phone, you order 6 of the same Ebay item number, and then clarify what you actually want in the notes. I couldn't actually find the M12 banjos on their Ebay shop, and my packing list gives what I paid for, so I can't help with actual part numbers.   I'm doing up a full table of all the bits I actually needed, I'll put it here and in the technical section, once I'm certain it's all right. Then learn from my mistake and maybe order it somewhere much cheaper :-(

Ok, the HEL banjo bolts fit much better, thank god. The world of brake fittings was entirely new to me, so I'm glad this is now bought for and I can get on with tightening, bleeding and bedding the brakes.  and connecting up the low-pressure inlet hose. Have to get a few more of this little black spring clips. You need 8, not the 5 I estimated. I have jubilee clips, but I want to keep the look subtle and consistent.  |

Ok, my final list of hydraulic brake components. I went braided all the way because I like the look, to avoid the mess of copper and to save on buying brake flaring tools. Like most builders, I have the Wilwood pedal box in the middle, I have the Hispec calipers provided by RTR at the front, Focus Lucas/Girling rear calipers from the donor at the back, and the standard 6mm OD brake/clutch fluid reservoir from the Focus supplying the wet stuff. I ended up overpaying for Venhill PowerHose Plus kit, and they don't actually sell all the bits (7/16"-20 banjo bolts) we need, so I had to pick up the rest from HEL. Maybe put a word into HEL or Stewart for a one-stop-shop price instead. The first group ('Low Pressure End') comes from HEL, was bought on ebay, link on spreadsheet. I ordered 6 of the banjo bolt, which is the same price as the banjo (£3.49), and explained in the notes what banjo I needed. Odd method, but it worked. Second two groups, ('MC outlet side' and 'Fiddly bits') are from Venhill, with their part numbers in brackets. Could be bought anywhere, just ask for equivalent parts; where I have PowerHose Plus, you could order copper or whatever other brand of braided you fancy. I haven't fit my clutch line yet, still waiting on that part, I'll update the price when I know. braided brake line components |

I beg to differ, I think my copper looks well neat   As for the flaring I got a man to do it, was free as I bought my copper from him. |

Why the s bend level with the mc's? That bend takes the copper back under the top tube and flush against the bulkhead, it looks odd in the photo due to the angle it was taken from. |

The man who sells me my bits doesn't do house calls on a sunday sadly, the only day a week I get to work on my Rocket. Braided looks lovely even with my skill level  Everything I buy has to come across the sea from a dominant economic neighbour at a great cost, but sure you wouldn't know anything about that.. |
