brake pipe supports
Hi guys. i've run into trouble with my brake pipes. They were cut to length by bgh and flared, in hindsight this is was a mistake...
I orginally planned to support the right hand rear pipe with nylon p clips along this rail.
but this leaves me too short to meet the other pipes:
so my question is what is the longest distance i can run a brake pipe unsupported?
this picture shows the other side, where i made a mistake, and plan to run it along the red route instead.
bgh manual suggest 200mm spacing for p clips, but 200+ of thin air?
any help appreciated.

Why not bend it into position and secure it. then lengthen with another piece of pipe and joint etc.

300mm centres and the pipe shouldnt touch the chassis.

If it were me I'd buy a flaring tool off ebay for £15 (I did) and get a roll of pipe for a tenner from a factors ( I did) and make them yourself
so you can put them where you like and make a really neat job of it. It's easy to do and satisfying too.
The ends are about 30p each in my factors too so it's not a mega money job.
All the best

I don't know who came up with that, but its not a rule in the IVA manual. The manual simply says "A brake pipe or hose must be adequately
clipped or otherwise supported". Which I don't think that section of pipe qualifies for.

IVA manual says 300mm max. Why would that be taking the piss?

Are you sure, what page?
I've just checked the latest version I can find ( 124_IVA_M1_Inspection_Manual__Version_4_0510.pdf ) and can't find anything beyond
"A brake pipe or hose must be adequately clipped or otherwise supported" as deezee says.
I seem to remember either the SVA manual specifying it, or it was something a tester was suggesting as "adequate" but if it was it
doesn't seem to be in the current version of the manual.

surely brake pipes touch the chassis at t pieces and chassis mounts for flexible hoses?

No, the T piece or the union is connected to the chassis, the pipe itself doesn't have to touch anything but clips. Whether that's banned
(now or previously) it doesn't appear to be in the current IVA manual explicitly.
The problem with pipes touching the chassis is there is the possibility they will rub due to vibration.

aha many thanks for that explanation. wondered if it was some sort of cathodic action they were worried about.

Ditto that. I've had to redo several bits, so it's handy being able to knock up another run. The pipe itself is dead cheap.
