After tuning for awhile I taxied around the ramp a bit and did a few minor adjustments, then got clearance for a high speed taxi on the runway. I did 2 high speed runs and the engine was tuned perfect (well maybe not as perfect as the autotune will do:-). As I neared the end of the runway, I decided that I would backtrack and ask for take off clearance to circle the airport while I checked the tuning in-flight. As I began to brake from that second run, there was a loud bang and I lost right brakes. Using full right rudder and light left brake I was able to keep it straight, but went 30' off the end of the runway before stopping (not a problem). Taxiing back with one brake was a bit challenging. I taxied past the charred remains of my wheel pant, then had to make a 270 degree left turn in order to turn right onto the taxiway. The fire truck has to do the runway sweeps after something like this so he returned the remains to me. It was clear that the wheel had been engulfed in flame, but it all must have gone out with the departure of the wheel pant. I removed my wheel pants for the initial taxi testing, but installed them for first flight and other than for inspections, they've been on since. I never really thought I was doing enough taxiing to cause a problem, but as this demonstrates, it doesn't take much. It shouldn't take much to fix the brake, but I'll need to closely inspect the tire and repack the wheel bearings with grease, then I'll be able to fly without wheel pants for awhile. I'll need to completely redo the right wheel pant. Unfortunately, next Sunday I head back to tech school (BCIT) for 2 months. I'd hoped to bring the plane down there with me, but it's unlikely now.
