Removing a stuck brakeline from a caliper
Next up on the trike was the front brakes. I had new brake lines to replace the old corroded ones, but the open end wrench just slipped on the nut. Partially rounded off fittings like this are a common problem, I wasn’t re-using the line, so I didn’t mess around and just cut it off.
Now I was able use a hammer to drive a six point snap-on socket over the abused nut and then turn it off with a 1/2″ drive 18″ combo ratchet/breaker bar.
Yes, I have 1/2″ drive sockets down to 3/8″ (and 1/4″ drive sockets up to 9/16″), and, as you can see, they are very useful. What if the 6 point socket slipped? I would have driven a 1/2″ nut over the fitting and then welded it on. This not only give you a fresh, larger hex to grab, but the heat helps loosen it up (but is much preferred to trying to heat it with a torch and possibly damaging the brake seals).
