Mine broke also. My KR had at least 100 hours on it with the old mechanical brakes and a pull cable. I added hydraulic brakes on the rudder pedals and I snapped a joint like Larry during my initial taxii testing and almost took out some lights at the end of the runway.
What I did was to get some tubing the next size bigger (sized so the 5/8" tube would fit inside it) and I made some corner reinforcement pieces about an inch long. I split them longwise and sandwiched them over the existing corner joints and welded. I also added some triangular corner gussets out of I think 1/8" material.
