Libraries of Things are a thing now. The items that are most useful are those that lend things that you use from once a year to every couple of years.
My local library (PEI Library Service) has a telescope, radon detector, a basic (and I mean basic) toolkit, some gardening tools among other things. The collection has a couple of surprises, but mostly underwhelming.
I did request something more practical, like a bicycle disc brake flushing kit, but this has not happened yet.
Auto part stores often will lend both weird and specialized tools, and relatively basic ones, too.
Usually the way it works is you "buy" the tool and then "return" it.

With the right gear, the job is still horrible. SRAM brakes give me an unlimited number of maintenance chores.
