I’m the cheapest bastard here, but probably the only one who always has spare brake pads with me. Changing them is easy AF. They’re as disposable as tires or chains or sprockets or even rotors (assuming your attachment hardware isn’t frozen) and would be thrown out if soaked in any petroleum products. That said I’ve ridden with fork oil-soaked pads and they can negatively affect the rotors surface as well. Rotors being harder to source when traveling, it’s just not worth it.
