Replace the plastic tubing in a noodle?

I'm not suggesting anything, just asking about the normal practice. Is the
plastic inside of a brake cable noodle replaceable?

If so, what plastic is used? I see nothing for sale as a direct replacement.

If the answer is "we just replace the noodle", that's fine too.

Thanks.

Technically, yes you can replace the plastic "liner" in a V-brake
noodle, just pull it out. Practically, it may not be possible as I'm
not sure whether the plastic liner is available as a separate item.

I once bought a large length of cable housing that came with a separate
plastic liner. I wonder if such a thing is still for sale? If so, it
would seem any bike shop that had it could sell (or give) you a 3" piece.

The "noodle" liner has a flange on the cable housing end which keeps
it from moving.

I see both Jagwire and Shimano "cable liners" for sale on e-bay.
Jagwire offereds for ~$7.00 for "two pieces" and Shimano for ~$8.00
for 1,800 mm.

I don't have any on any of my machines, but did install a pair on an
MTB for a lady with small hands to increase the cable travel distance.
However, at $20 EACH, it's a rather expensive way to get rid of the
noodle. It also tends to get clogged full of dirt, but disassembly
and cleaning is quite easy.

There's also the RavX Super Noodle:

which will require replacing the brake cable housing to extend the
extra distance.

On Amazon... "Jagwire Black Housing Liner 30 Meter Roll, Fits up to 1.8mm
Cables" for about $7.50 US.

One reviewer wrote "you can use this inside of brake noodles. This can be
applied to bottom bracket guides as well". Others talk about using it for
in-frame cabling.

A hot piece of metal might work for making a flange, but that's for later.

Thanks.

Using a roller makes sense to me, but I'm not so sure about using the cable
in place of a noodle. Some plastics are self lubricating and wear better
than steel. That's probably the idea behind the noodle... Slippery.

Thanks, I was wondering about using a pulley or a roller.

If I was desperate I'd try a ball point pen refill, but honestly I'd buy
a new one.

That's the theory when both the cable and noodle are clean. Add some
dirt to act as an abrasive, and the plastic is likely to become gouged
by the cable. You can add lube to the equation, but the dirt is still
going to dig into the plastic. The reasons that the noodle doesn't
destroy itself is that the lateral (side) pressure by the cable on the
noodle is minimal, the cable travel is short, and number of brake
cycles are few. If this were part of a continuously reciprocating
mechanism, the sleeve and noodle wouldn't last very long.

Notice in the YouTube video above, that you can run the cable around
just the outer pulley to replace the noodle without adding additional
cable travel. Starts at 1:01.

Yes and no.

It's a PTFE tube with a flared top (so it won't fall though
the noodle. Could be fabricated from a section of brake
casing liner flared with a cigarette lighter by pushing the
hot tube over a section of brake wire in a vise. I haven't
done that but have done similar projects with that material.

OTOH noodles are dirt cheap and available everywhere.
