Brake Line Charts

In order to keep my own sanity I have created some brake line charts over the years. These are all based on cars and brake lines that I've gotten my hands on. I've tried to be as accurate as possible but I welcome any corrections and/or critique. I will add to this thread as I gather more info.

REVISED to Version 2


So here is the chart for Duetto brake lines running ATE calipers. The includes the lines with and without vacuum boosters:

The pictures aren't all that clear - Here is a PDF file:

Duetto Brake and Fuel Lines V2.pdf

And for those who may be interested, I have contracted a source to create brake lines using my patterns in stainless steel with the correct fittings. If you are doing a complete brake job and not inclined do the bending and flairing yourself this is a welcome option. I currently have them for '66-'68 ATE Duettos with and without boosters, '69 1750 Spiders with dual boosters and '69 GTVs with dual boosters. These are all floor pedal, left hand drive, USA version systems. I will have hanging pedal lines in the near future. Also, the Duetto lines should be the same for the Stepnose GTs with the exception of the long rear line (R1 in my designation) which is longer but I don't yet have that value or the pattern.

Pricing is yet to be determined but if you are interested, please PM me and I'll see what kind of a discount I can get. I do know that the SS was reasonably priced compared to buying conifer tubing and all the fittings and could be a cost savings if you have to buy the flaring tools for one job.

Yes but the fittings would be made out of Osmium...

Rich, wondering how you are coming along with the hanging pedals? I would like to replace all of my brake lines and this and your previous thread were great info. I have a '71 1300 Junior, the style after the stepnose. Three lines coming off the brake master cylinder, one going to front left, one to front right and the third going to the rear.

I'm not sure if these were redone in the past and are correctly set up. I have the short booster and dual cup reservoir. Thanks.

The hanging pedals are a dream compared to the earlier brake lines. That said, I haven't had a chance to lay out the front lines yet. What you describe sounds correct, FWIW.

I did run into to a delay with the lines that I am making up currently. The fabricator is suddenly swamped (who knew that the was a season to brake lines) and they are behind by a couple of months. I need my lines back to finish a couple of projects so I am going to hand made a set and then send them back to get digitized.

I am hoping that anyone that has expressed an interest in stainless steel lines can hold off a bit while this gets sorted out.

LOL, No need to beg but I would need a donor set of lines to digitize...

The dual circuit Spiders are virtually the same as the GTV with the exception of the length of the rear line (my R4a) which I believe is 4" shorter (114" vs 118").

Thanks! I see now. I looked quickly at your table and saw only a single booster, I didn't realize it was one table per circuit.

Looking at the diagrams, am I missing seeing the flex hoses, or are they not included? I have the rear flex pulled, to be replaced, and where I live Alfa parts are not easy to find, but we discovered that the front hoses match a Hillman Hunter (1" longer). Before I take the several hour journey to the supplier, if I can call him and spec the hose, he can tell me if he has an equivalent.

Flex hose rear: 39 cm long
Male on both ends
From Pro. Valve end: Is it M10.1 Din and if so, what flare?
To Tee end: Is it 10mm.1? and it looks like a flat end, no flare.

Thanks
