Hi Rich et al,
As a starting point, a huge thanks Rich for taking the time to put this posting / chart together - much appreciated!
I'm deep into the complete brake line redo of my '67 GTV which, when I acquired the car, didn't have a booster - it had clearly been bypassed. At the risk of being wrong, I'm making the assumption that the brake lines for a '67 GTV would have had exactly the same lines / tubing ends - albeit the lengths of the lines would be somewhat different due to the geometry of each car (wider / longer, etc...). Assuming this assumption to be true, I have a couple questions from your chart:
1) For Line F3B (Vac Booster to Tee Fitting), I'm thinking the Vac Booster tubing end should be a "M Bubble" whereas the Tee Fitting tubing end should be a "M Flare". On your chart, it indicates the opposite of this.
2) When you refer to "MALE" in the two Fittings columns, I assume this has the same meaning as "M Flare" - is this a correct assumption?
Lastly, I've attached pictures of the two Vac Booster female connections (both identical w/ a "flat" bottom) and the 4Way Tee middle female connection ("conical shaped" bottom). To my ill-experienced and clearly novice eyes, this is what I've based my above conclusions from.
Best regards and I look forward tp comments from the BB!
Looks like this thread has been quiet for almost a year, but I am going breathe some life into. I too very much appreciate the Table Rich has provided. I am putting into Excel to help me do the math. I also need to add the disclaimer that my car was completely disassembled by a PO in the first 15 years of it's life, so I can't say that anything is as it left Alfa's control.
First to address Chuck's question (probably already figured it out for himself since it is 10 months old). I am working with Rev. 4 of his GTV chart.
In my 1969 USA Spider with Dual Circuit, the line from the front booster to the 3 Way Tee (F4 in the chart) splitter has a DIN flare at the booster end and a SAE flare at the tee which if you strictly interpret the position of the From To columns with the fitting columns, my car matches the table as far as type of flare. When I measure the OD of the threads with a caliper on the fittings I am very close numbers to the sizes in the table, so I feel confident that Rich's values there are correct. That is what I am planning to order.
2. I would find the pictures of DIN and SAE on the board. That made it clear to me. This is my first time replacing brake lines so I was confused at first too. Local AROC member going to help me flare everything after I get it roughed in.
For Line R4B, the strict interpretation of column location is backwards, but I can't imagine that is causing anyone problems.
The disparities I have found between the table and my car are R5, R6 and C2. For R5 and 6 I have an SAE flare at the tee end. That would seem to be consistent with the Tee at the end of F4 that is installed at the firewall for the front brakes. The chart lists DIN for the Tee end. For C2 I have an SAE flare at the end that connects to the flex house instead of a DIN as listed in the chart. This too would seem to be consistent when mating to a flex hose as seen in F5 and F6. BTW the flexible clutch line had no retaining nut on as found. It did pass through the hole, I guess I should be thankful for that.
My only other comment to the chart and I recognize this is nitpicking, but F5 and F6 don't connect To the Caliper like R5 and R6 do, but instead connect to the fixed point and flex hose in the wheel well.
