Keith,

If the compensator port doesn't seal when you step on the brake pedal, the brake fluid displaced by the hydraulic plunger goes back into the reservoir. As the resevoir becomes full, some of that fluid would follow the passage, to the rear, down to the bore for the seals, which terminates between the hydraulic and leather seals.

All other things being in good repair, I believe only a small amount of brake fluid could get into the vac shell, in that case.
