How much and how frequently have you been adding brake fluid to your car? If this just started and you have put only a small amount of brake fluid into the system I would think it would be OK to replace the master cylinder only. The brake booster should have no brake fluid in it at all. I just put a master cylinder and booster on a car, the owner said he had been topping up the brake fluid every week for the last 6 months. The brake booster had about two full cans of brake fluid in it.
