He said L-33 in the title. I work on a couple of L-33’s. I don’t think anyone makes a hydraulic brake conversion. The wheel on it is proprietary Blanik. It’s the same wheel off L-23 and 13’s. Interestingly it was supposed to be set up to retract but they never got around to it.

Thanks for answering. The only two non-aircraft specific conversions I found were strictly for Tost wheels. Guess I'll stop trying to find something to tinker with and just fly it for a while
