Thanks mate I get the large spring that links the top of the shoes together but what does the smaller spring do and what does it hook up to???

The large spring on the linking rod is the actual return spring.  The 2 smaller springs on the brake shoes just prevent them from flopping around inside the drum!

Some US models got 2 extra springs linking the brake shoes internally, just like a conventional drum brake.  Apparently the DOT didn't trust the factory set up.

those little springs are the same as the detent roller spring in the gearbox

... this same gearbox spring being a perfect return spring helper for the early Grimeca drum brakes!

.. and the rod of the early Grimeca drum was in turn used for the gear shift linkage of drum brake SFCs!

  .... and those little springs are not only the same as the gearbox indent spring - they are the same as the seat lock lever return spring on a lot of models - Laverda  wisely did try to economise where it could - regards - Phil
