Hey Kilo Papa,

Have you considered sending the brake to Vintage Brake in Sonora, CA
(http://www.vintagebrake.com/index.html)? They are familiar with the
TOST brake and charge about $175-$250 to improve the brake's
performance. A search on RAS has will indicate that they reportedly do
good work. I had a TOST brake re-worked by them but haven't actually
tried it because I'm STILL waiting for the repair on A5.

Hi All
Our drum wheel brake on the club Grob 102 is almost useless. I was
wondering if there is a conversion to a diskbrake.
