As part of my re-build, the engine is being fully stripped including paint being removed and when doing this to the bleed off pipes, I found this:
So, the question is, whats the best approach, remove the fittings (they look to be soldered rather than brazed) and replace the pipe with copper brake pipe?
Also, here's a little pic of my cracked head (replacement sourced from Agriline)
A minute or so with the blow torch resulted in a nicely detached fitting and standard copper brake pipe is the same outside diameter (internal is slightly smaller but I suspect that this wont be an issue).
You are right. It's soldered. You could solve it like you say, but the part is new to buy for the major these day's. About 25 to 30 euros. Don't know if theres one for the Dexta.
Hi Russelm
You have found the problem and identified a 'fix' but what was the cause?
What is routed in that area? Wiring or something, that what you must find to prevent it happening again.

The damage to the pipe looks as if it was caused by corrosion. If it had been chafing on another pipe or wire then the pitting would be smooth and bright.
Using a slightly smaller bore replacement pipe shouldn't cause any problems, as the amount of leakoff should be minimal.

Hi Jerry
Pretty sure its corrosion as other areas of the pipe are also pitted (although under the removed paint).
So, brake pipe repair it is, I will post a picture of the finished item.
