I can adjust brakes, it's my job, I just don't like to!
I like "fit and forget"

Brake conversions here are no problem, we can pretty much do anything we want with cars here so long as it meets our quite basic safety test (MOT) which is once yearly.
We do not have to mark any modifications on our log book (V5, same as your Fahrzeugbrief, sorry, probably spelt wrong but I'm sure you understand)
I have not seen the info in the WiKi? do you have a link?
