ATF versus G60 versus Brembo piston sizes.

I've put a couple hundred thousand miles on different 200q's with UFO and G60's over the last 12 years. IMO, the UFOs have far better braking ability.

I've heard many times that effective area is the same but I am unable to find actual ATE piston diameter to verify the statement.

Recently somebody described here that after ATE -> G60 swap the brake pedal travel increased. It means that ATE (UFO) effective piston area is smaller.
