Working on the VW, installing top German-sourced brakes (folks, it's the first millimeter of reaction for whatever else is going on. take your time and don't scrimp. diy is not scrimp)
There's a logic, four points of contact and a couple of anti-vibration wedges but pretty straightforward. Goes together precisely with brakes made to MOT specs.
Backwards. I had put two rear pads on. I discover this with the wheel on, but not on the road. Back apart, zoink, back together. No caliper pressing this time.
So.. their design was precise, but allowed such errors to happen.You fool, you will learn from your incompetence.
My experience with Japanese cars is a narrowing to a precision. If you get this lined up with that, then harmony is achieved and completion is occurred.
Else it is all a mystery and one should step back and consider intent.
My narrower experience with American cars/ trucks shows that a hammer is a recommended part of the toolkit.
Italian.. French... Swedish. Korean. Australian. If they originated the design (not a 'world car') the culture is reflected in how that #(($# bolt turns, how durable it is, how precise it must be installed, and how much gasket is required.
Sometimes whole principles are off-kilter, so someone competent in one discipline will fail applying it to another. How many VW beetle engines were wrecked from otherwise decent mechanics? more than one.
Knowing a couple of curse words in the vehicle's native language can help, sometimes.
Am I talking nonsense? Well, yes, but what expectations do you have when you encounter a particular culture's mechanical products?
