Some shops do it, but you shouldn't go to them.
All it takes is a couple feet to move the torque required into the lower end of human capability.
But it still happens. Having a means of greater torque gets past that failure condition and reduces the work burden.
And that's a net good. Older people, young, small, women with nails, guys who may not be very strong, someone hurt or sick all see a much improved task, well in bounds for them.
This is precisely why I brought all my kids up knowing these things. Same for anyone I've helped. I'll leave it with them and just go get another lever. cheap.
Better to be equipped to get this done than be stuck, merely understanding one should not be, but is anyway.
A small extension of this thinking means equipping the vehicle with common sense, useful tools. BMW does this from the factory. Most go unused, but its ultra cheap insurance. May actually end up applying to another vehicle. All good.
It really doesn't take much to equip a vehicle for trouble cases. Anyone who does is likely to get a nice return on that modest investment in skill and gear at some point in their lives. This is true even when their skills are somehow lacking, or they become physically unable somehow.
Getting help means people, and it often means tools. Having both is again, cheap insurance.
Talking about a damaged fastener on your way from the trouble incident is a great problem to have when compared to the side of a road.
The fastener problem is real too, but not nearly the potential safety hazard as the damage to the brakes.
And, given they must do that work, having the means to complete it makes all the sense in the world.
Nobody has to tighten anything that way. I've never shown, nor recommended people do. It's all about having the means to change a tire, should that need arise. And that means removing the fasteners.
So, I'll tell you what. I'll continue carrying a lever, and will continue to not be stuck somewhere ugly, and you do whatever you want.
Everyone can and should express concern when the job is done poorly.
Nobody should be stuck because it was done poorly, unless they want to be, and I for sure don't. Nor does anyone I know.
I'm getting older. Can do it. Just don't want to. May not be able one day. There is that too.
