Torque shop: What if my car's brake fluid is leaking into brake booster?

If my car's brake fluid is leaking into the brake booster, do I replace the booster, the master cylinder or both?

If the master cylinder is leaking, it will need to be replaced. Since brake fluid has leaked into the vacuum booster, it is advisable to replace it too.
