Where did you find a brake line to purchase that would fit the Grob?

as most replacement motorcycle parts do not either, the master

is

separate part number from the external brake lever handle.

What do you mean by "swap over the lever"?

Old cars normally have steel brake cyliders, the BMW part we are
talking
about is aluminium. Putting a steel or brass sleeve in will almost
certainly cause corrosion (disimilar metals).
A new part is available and is not expensive. All that needs to be
done
is
to swap over the lever.

Look on the bright side, at least he isn't in the UK. I'm pretty
sure
BMW don't supply brake cylinders with EASA release certificates. I
can
imagine:

1. Brake cylinder from BMW: =A3100
2. Identical BMW brake cylinder the man from EASA has sprinkled magic
pixie dust on: =A3350
3. ??????
4. Profit

After replacing the master cylinder on our ship we found that the
problem was with the brake line linking the two cylinders. *When we
replaced it the problem of poor braking was solved. *Must have been
unobservable expansion within the OE line!

As I remember, it came from Grob in Bluffton, OH but now they are out
of the parts supply business ?!
