I have always thought this. Since I started fixing my own bicycles, cars, boats what ever, I learned quickly to try and identify the hardest Bolt, screw, whatever and make that the first one to work on. But some how it still comes down to the last thing, when you're the most tired, that you face the biggest challenge
Well I was again amazed at how true the Last bolt curse is. I was Flushing my brakes. Got all the way round to the Driver front. Bleed the Outside, went to the inside and OMG, I could feel my Flare wrench turning but just starting to round off the Bleeder value. I suspect rounding had happen before me. So the perfectionist in me thought about Vice gripping it. Then the wise old man in me figured, no way, this thing will go side ways for so little gain.
So maybe it wasn't a curse but a good thing it was the last one in the bleeder chain.
At some point in the near future, I'll want to refinish the calipers, so that's when I'll replace it.
