Yet another tire went flat on Ranger and havent got it on road yet. Bead leak so break it down, wire brush, paint, put it back together. This one however had some green antifreeze looking stuff run out when I broke the bead. I cleaned it out before remounting tire. Just wondered what the green stuff was. Never heard of anybody putting antifreeze in a truck tire before and a tubeless one at that. Another nice surprise, while I had wheel off, I thought ought to pull brake drum to see how shoes are wearing. No innards. No shoes, no hardware, no pistons in the wheel cylinder. Drum is deeply grooved probably cant be turned. Takes a genius to disable half the brakes on his truck. Whats got me is the master cylinder is full up and I cant find where the genius crimped the line. Didnt do it where I could see it from the back and not up around the master cylinder. Guess I got to trace line from front to back. Oddly the front rotors are in excellent shape. Do need to put in new pads.
