My '55 Victoria has power disc/drum brakes installed by a previous owner of the car. Recently while driving I noticed the brake pedal was soft and loosing pedal height. I was local, so I drove it home to check the brake fluid and leaks. When opening the reservoir, I noticed brake fluid on the brake warning switch and on the distribution valve and inner fender. The reservoir was empty. I replaced the switch and refilled the reservoir. Now the brake pedal is at normal height and firm. I drove the car yesterday and noticed that increasing brake pedal pressure doesn't increase braking. I wonder if my split system is activated and how to reset it. Thanks for advice you might have.
