The master cylinders on Volvo’s seem to last forever. We have so few replacements documented here compared to other makes I’m familiar with.
Normally I'd agree but since most vehicle owners don't do PM's, especially brake fluid service intervals. Example: About 6 months ago a customer of mine brought me his 2003 P2 XC70 and the brake fluid system was totally contaminated.
The Master had to be replaced because seals were failing and if I remember correctly one of his rear brake calipers was leaking at the piston seal. I had recommended replacing the MC, rear caliper, the soft lines to caliper, doing a total flush of entire brake system. It looked like someone had introduced a foreign substance into his reservoir.
