front brake flexi pipes

[onedayTM]

I just want to clarify the fixing brkt point as from pics of finished cars they show the pipe connected to the side panels. Is there an issue with the pipe catching on bodywork if fixed to the chassis brkt? or is it still fixed to brkt but has a grommet fitted to pipe to stop it rubbing on panel.

From experience, terminate it on the side panel. Or at least extend the bracket out to touch that panel. I built it by the book and it's a pita that way.

Grommets are a no and iva fail.

i put tags on the chassis as per book
if you have metal sides then you could mount on them on there but if you have any vibration or movement on copper brake pipe then it work hardens quickly and will crack!

Ok, but how did you achieve going through the side panel? Any pictures you could share?

I have been thinking about this problem too, and I think a grommet seal is a good solution. But do not use the rubber grommets you use for electric cables or pipes trough the bulkhead. There are special nylon ones for flexi lines, which must be used. With these nylon grommet seals, the hose, which by definition is flexible and always moving, can slide in and out inside the grommet due to the waxy nature of Nylon. The hose stays free to move, and don't force on the wall it is attached to (this might be important to think about, to avoid cracking/damaging the gel coat of GRP side panels.). This would not be possible with rubber grommets.

I could supply my brake lines with this kinds of nylon grommets on the front flexi lines, on request, for a very small extra cost. This is actually something I'm seriously considering now.

Just an idea to make your life easier

Thank you for pointing that out !

Sylvian - how did you end up doing this in the end? I am using the same bodywork as you I think - and was going to make up the brake lines this evening (but haven't fitted bodywork yet). I do have the 'book spec' brackets though - so could use those if it's then possible to exit the body with the flexi lines using a grommet to make it all look nice and tidy...

Hi John,
Honestly, the front flexi lines brackets being so close to the wishbone brackets, I just made the wishbone cuts in the GRP panel a bit larger. Finally, I think there is no need for a grommet here.

The hole enlargement doesn't need to be big, because the brake flexi hose movement is almost nothing that close to the bracket.
