MogLite Posted March 31, 2006 Share Posted March 31, 2006 I'm currently running the brake lines on MogLite, using the regular copper-ish brake pipe. How do you get the brake pipes neatly through bulkheads ? Merlin motorsport don't seem to do a suitable fitting Drilling a hole with a grommet seems a bit low-rent to me, I'd prefer some kind of bulkhead fitting. Using a male-female connector is possible I suppose, but it doesn't seem quite right. Quote Link to comment Share on other sites More sharing options...
minivin Posted March 31, 2006 Share Posted March 31, 2006 Goodridge do bulkhead adapters, might find something here: http://www.goodridge.net/uk/pdf/GoodridgeCatalogue2005.pdf Quote Link to comment Share on other sites More sharing options...
Tonk Posted March 31, 2006 Share Posted March 31, 2006 do u mean a fitting that bolts in the bulkhead as a guide for the pipe to go through or a connection for the pipe to go onto? i always avoid unnecessary joints.......... Quote Link to comment Share on other sites More sharing options...
minivin Posted March 31, 2006 Share Posted March 31, 2006 i always avoid unnecessary joints.......... Yeah, always a bit of a horses-for-courses thing, whether to consider it another possible leak-point, or whether to think of it as a point so that if a pipe gets damaged, you don't have to replace the whole run.... if the joint is properly flanged (decent Sykes Pickavant style tool et cetera, not the cheapie £10 jobbers), and well assembled I don't see any serious issues developing. But nothing is ever guaranteed Quote Link to comment Share on other sites More sharing options...
Tonk Posted March 31, 2006 Share Posted March 31, 2006 why run it through the bulkhead, strap it up under the chassis/cockpit area and it'll come to no harm imo, they only ever get snagged at the wheel areas Quote Link to comment Share on other sites More sharing options...

ISWYM - but I was thinking of something like this I can't see that a guide would be a lot different to a grommet. Can't see anything in that Goodrich catalogue for hard-lines Quote Link to comment Share on other sites More sharing options...

Running the brake lines along the top of the chassis, and then to the bulkhead for all the fittings is my plan. Quote Link to comment Share on other sites More sharing options...

Can't see anything in that Goodrich catalogue for hard-lines Just found a pair of Convex fittings for bulkhead, 90 degrees bend on one side, fitting onto I think a panel upto 8mm, 10mm at a push, got two blanking nuts, think 7/16" UNF fittings, I'll bring em tomorrow if any use Quote Link to comment Share on other sites More sharing options...
Tonk Posted March 31, 2006 Share Posted March 31, 2006 well i've never used olive fittings in brake lines, how much pressure is generated under braking? i dont really know. i've used olice/compression fittings on pas set ups, they hold that pressure fine.

02GF74 Posted March 31, 2006 Share Posted March 31, 2006 someone like Roger will enlighten us. but the problem as I perciev it to be is that any movement between the bulkhead and pipe, the bulkhead being thin will concentrate the wear in a small area of pipe especially one with no protection (not what you're proposing) - and it may over time wear through a grommet. I cannot see what is wrong with the bulkhead connectors? So what if it increases the fittings in the piping by one or more? If you can make good flares, then it doesn't matter if there are 1 or 20 joins in the pipe - surely if you make brake lines for several cars then the number of fittings will be more than those on say the one car so the if failure rate is the same. you have the same problem (sorry - probably not explained that well). If extra joins are a nono, then I would look at increasing the effective thickness of the bulkhead - fitting a length of rubber tubing inside a metal tube e.g. a domestic heating fitting that goes through a panel.

Les will not go wrong totally agree; but the question is will one bit do the job re: chaffing. I am thinking hard but not come across any car or bike I have owned that has brake lines passing through a sheet of metal. As for joins, consider front brake pie: union at the master, then union in and out of the junction box, then union on chassis to flexi hose, then union to another soild pipe then last union at caliper/wheel cylinder; adding one more is an increase of only 16 %, not that mcuh of an increase? I've put question on antoher forum and will update if there are any replies. Quote Link to comment Share on other sites More sharing options...

mmgemini Posted March 31, 2006 Share Posted March 31, 2006 Simple... Well I used to buy a long double female brake tube connector.Ford fitted them to the Transit of the time. Or from Vehicle Wiring Products page 37 in their catalogue.Part Number B598 drill a hole in the middle of a large penny washer and braze the fitting in. Drill two or three holes in the washer to bolt it to the bulkhead. Simple !!!!! HTH Quote Link to comment Share on other sites More sharing options...
