Replaced trike handle bars, AGAIN

I had given up on the 1st set of replacement bars, they were not the correct size for the stem and my work around didn't hold it securely. I was literally on my way to "The Lab" to look for a replacement, when I hit a pothole and the screw snapped, eliminating the possibility of further delay. While I was there, I collected some mountain bike brake pads and adjusted the hub brakes. My dad cut down the excess bolt length in the breadbox with a Dremel for me. I'm looking for a pitbull on ebay to replace the whole sidepull brake unit. Got to have optimum braking power with a kid on the back!
