JJ,

I did purchase a master cylinder from a BMW motorcycle dealer that did fit
in place. Unfortunately it did not function properly. It was properly
bled and all but it did not work. I don't know what to do next. There
must be at least 100 of these gliders in the US that will need a master
cylinder replacement in the future. I don't see how we can junk a $30K
glider for lack of a functioning master cylinder.

Thanks for your comment,

MC

If memory serves me, its a motorcycle master cylinder BMW? I believe
they cut it down from the original, good luck getting your inspector
to sign off on installing it!

My club has a 1983 Grob 103 Twin II that needs a new master cylinder.
Over
the years the Grob factory has made changes to the system without full
documentation and as a result the US distributor can not be sure of
how
I
go about purchasing the proper master cylinder for this glider.

If you or anyone you know has replaced the master cylinder on a
vintage
Grob 103 Twin II recently I would appreciate your input on where I
might
purchase the correct system.

Thank you,

Mike
