I read the description but it’s a bit confusing. Each pad has 2 pins that go through it, so even if you lose one pin the pad should still be held in by the second pin (in a regular 2-pad caliper).
So I don’t understand how he lost his pads? Unless he had a 4-pad caliper, and therefore he would’ve lost 2 of the pads, but then wouldn’t he have still been able to stop using just the other 2 pads?
But then I guess what would happen is the pistons behind the pads that fell out would push out into the rotor, and therefore he wouldn’t get any pressure at the lever until he pumped it a few times.
