Subject: Brake pipe joints?

Is there any reason why there are several joints in the main brake pipe run to the rear brakes? I'm replacing in copper and could add in the same joints but could also have do it without. I will retain the joints around the bulkhead but this is for aesthetic reasons.

Thanks

Copper is easey to fit malleable. Old pipe plated steel made
to a drewing and gig, also made in section for easy replasement. So no there is no reason not to replace it
in copper or Cunifer 10 trade name.
Ps make shure your OP-1 and OP-2 are correct.

Hi
OP-1/OP-2 are the methods of flaring the pipe.OP-1 forms the olive shape for concave fittings.OP-2 flatterns the OP-1 form for convex fittings.Have a good look inside all of your fittings.
Cunifer 10 is better than copper pipe it is acopper/nickel mix stronger than copper. If you have a good flaring tool it should be marked on the flaring dies.
