Brake Line JigSaw Puzzle!!

[FMD159]

Hello part of my 1750 ground up restoration has now lead me to do renew all the brake line plumbing.

Series 1 1750 with a single booster brake system.

I have had all the lines made with appropriate fittings and lengths based on the exsiting lines which were in bad shape.

The new lines have not been bent into shape and are in straight lengths. I am looking at the old lines and trying to make head or tail where they should go...also I am not confident that the old ones are in the correct shapes as they were originally "ripped" out so I am not sure how and where to bend the new ones into the appropriate shape...

Does anyone have any advice on the best approach for this, I dont have bending tools ? Does anyone have any guides or pictures of these lines etc that may help me here?

If you don't have any pictures or can't locate any pictures, the parts book should help, some.

I'd start by mounting up the booster, reservoir, pedal box, brake MC, Clutch MC, etc. Using this page from the parts book should help you get started figuring out where the lines go. They will only go in one way. If they are bent out of original shape, you could try and make them fit. Be careful not to bend them too many times as they could crack. Them you can use them as templates to bend the new lines.

Most people that I know will use hanger wire to form templates. Hanger wire is easy to bend and very cheap to replace.

another option would be to use copper tubing of the same size to create the template part...this will allow you to make the straight lengths between the bends even closer to the final part....and of course copper is super easy to bend.

guys tyhis has been most helpful....question does anyone have aphoto of how the piping is connected to the brake master cylinder. I do not have the Ate type master cylinder, I have the bonaldi type and not sure which is the inlet or the outlet of how to connect, ist such a tight angle!!

[papajam]

Rule of thumb is that the inlet is in the vicinity of the front (pressure side) of the piston while the piston is at rest. The outlet is toward the end of the piston's travel when it's pushed.
In other words, the inlet on your single circuit M/C is the fitting closer to the pushrod end; the outlet is closer to the sealed end.

OK guys...I am trying to find illustrations and photos of examples of how to best run the brake lines and clutch line reservoir in the engine bay....can anyone help?

...ideally for rhd single circuit configuration...but LHD is ok as well i will get the idea....

.....this community is a wonderful reasource and I hope to give back by completing my thread with the results of everyone's advice....

Frank,
last night I proceeded to re-install my old brake lines and M/C so as to take some photos for you. However I then realised that the steering box, boosters, clutch and pedal box should also be in position since the lines need to wrap around these items. I won't be able to get all these installed for at least a couple of more weeks....if you can wait till then I'll shoot some photo's and send them to you.

[1750GT]

Those photos show the routing to be significantly different than for a RH drive GT....so any photos I would have taken would not have been of much use to you...even if you were to symmetry the installation. As for the bracket, most are not much more than flat bent-up pieces of sheet metal which your body guy should be able to tack weld on quite easily.

[FMD159]

I want to purchase brake line clips which I can fasten to the engine bay to neaten up my piping. I am looking for multiple pipe allocations per clip...anyone have any ideas where I can find something like this?

At the time I was going to, but instead marched on with the rust repairs on the body. Again, my car is a dual booster US car and I don't imagine the routing would be applicable to your RH driving car single booster car....would it?
