I watched about half of it.
Drums are low wear items, I don't agree that they might last four months. A brake fluid flush is recommended per the manual, every three years, so that is likely in the right.
I sense a bit of working to make a story. There could have been unevenness in the brakes, how am I supposed to know?
But many of the other things are just so dumb it's incredible.
But it's also important to be an informed customer.
