A mysterial is a mystery brake pad material of unknown quality, origin, performance, degradation or composition offered by a brake pad manufacturer for which no fucks are given as they should be focusing on a reliable supply of their popularcore product offering.
Today I received a phone call from a manufacturer offering a new mysterial when I can't even get a supply of the popular materials.
