For mounting the hydraulich brakes of Mecatech to the Cleon you need the Harm adapterplate 1515920-40 to mount the brake saddles.
The original Cleon wheel squares need to be filed of slightly on the outer edges to make the original Mecatech brake pad fit.
Elcon brake pads 18809 do not fit.

Note there is no hole foreseen in the standard Cleon radioplate for a 3rd servo. On request we can foresee an extra hole for an extra brake servo on the by you advised/desired place.
