I had Michael "Mercury" Morris overhaul my Tost P.O.S. err I mean drum
brake. The new pads and blueprinting (as described by Bob and others
in this thread) significantly improved braking and fade resistance.
In addition, Mr Morris found and corrected a worn/ovalized actuator
arm and hole on my Tost.

I would recommend Mr. Morris and his modifications highly.

That said, there is NO comparison between a (modified) Tost drum and
a Cleveland disc brake. Putting anything less than a 500X5 Cleveland
on a modern glider is ignorant.
