Do I need a bleed nipple?
Hi all,
I am planning the run of my brake pipes. I am considering running the pipe to the from left brake across a chassis support that is slightly higher
than the master cylinder - no more than 20mm above the max line on the reservoir. The line is shown on this photo in red and you can see the master
cylinder.

I have the option of using a three way connector at one of the ends to make the 90 degree bend, with a bleed nipple in the third outlet. I would
rather not - the question to all of you that have done this before is whether the nipple is essential?
Thanks
JC

Not essential. Plenty of systems have loops that, in theory, could trap air and make bleeding difficult but it shouldn't be effect it in
reality. Putting the T in just means more places to leak and I wouldn't unless splitting the pipe that way made fitting replacement/easier.

Because the pipe is very small bore the trapped air will get flush through as a slug of air.
