BRAKE FLUID LEAK AT FIREWALL

Brakes problem

I have a minor brake fluid leak at the interior side of the firewall were the brake actuator rod enters the master cylinder assembly.

Is that most likely the hydraulic booster seal?

Should I replace the master cylinder as well as the booster?

If the booster is sucking brake fluid from the master, replace both. Rear seal of the master is damaged as well as the diaphram of the booster.
