[TowerTalk] Add on 3" mast brake?

[Jim Kinney]

My son's Audi SQ5, had an electrically operated parking brake built in to the caliper. Might be available in other models.  You might check the junk yards, or even auto parts stores.
Shouldn't be hard to build a bracket for the caliper, or an adapter for the brake rotor.
You could cut the rotor in half to mount around the mast so you don't have to lift mast/antenna.   Bevel the edge of the cut to ease it thru the caliper during high speed contest operation.
