Dudes, please keep me plugged in on this topic. I am
planning to rebuild my master cylinder and it is of
the same type described by The Roxter. I've rebuilt a
few MCs before (Jaguars) but never an MGB. As we
attack these beasts lets make sure to photograph and
document the procedure. Kelvin makes a good point.
If its a hard job then there's all the more reason to
document it.
best,
rick

Italian iron too
