Brake Pipe runs

[Andy Green]

Well, I’m on another business trip to <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com

</st1:country-region><st1lace w:st="on">China</st1lace> and wide awake at 4am, due to jet lag. I’m currently, considering whether I can put the brake lines inside the main chassis tubes on my Tornado, as I don’t want them under the car or in the cockpit area.

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<img src=" /><o></o>
The plan would be to pass the brakes lines (I plan to use Cunifer, a copper based alloy used commonly in the UK for brake & clutch lines) down the main 2” chassis tubes and to locate the pipes, inject expanding foam at 6” intervals to stop them rattling. By pre-coating the inside of the tubes with waxoyl, it would stop potential moisture or any corrosive reactions. I’ll use grommets on the ends to stop any potential chafing.<o></o>

Does anyone foresee any problems with this idea, or I could just run them down the central tunnel with the main coolant pipes!<o></o>

I'm not sure on how SVA wuld take to your fixing method - but if the pipes are fixed at shorter than max spacings there is not much they can do - but could you prove it to them?

How about some expanded foam / meoprene rubber made into say 1 inch thick (Or Cube) washers with the pipes running through them. Feed it into the chassis rail with the aid of a hollow square section and position them the 6 inches apart (Stop rattles and avoid the expanding foam which can be a bugger to move if you ever need to)

On the Dax they are run along the chassis under the cover over the sill mount gear change mechanism. This is a fairly large space (In Gt40 Terms) and is also where I ran the electrics / loom.

Another thing to consider is your planned use - it is said that with the Renault slave (about an inch and an eighth) it requires such a large volume of fluid to move it that in the standard size pipe the volume of fluid flowing the pedal to slave distance causes the clutch to release too slowly. For race applications this may be a hindrance. Some have fitted a larger diameter pipe for the clutch.

- Just some more ideas to keep you awake

Cheers

Hi Ian

Many thanks for your feedback. I need to read up on the SVA requirements regarding support for pipe runs. I was already considering using a 1/4" pipe for the clutch pipe, especially as the Lotus Esprit uses a larger diameter pipe.

Andy,
you have a PM.

Agree with the 1/4 clutch pipe. My first GTD had it and it made a BIG difference.
