duBro made or still makes a nose or main wheel brake that has a small hub that keys into your wheel hub and has a loosely wraped spring that's around the hub and anchored to the gear leg. The spring has a extended portion that a small line attaches to and then that goes to a servo. Servo pulls>spring coils tighter around hub>hub drags> wheel stops. Kinda?! it actually works well and I have 5 of these units NIB for planes that come in hot. Currently all of mine are tail draggers and it's just a bad idea to put it on those. The duBro # is 157.
