Brakes - advice wanted for improvements

[AdamIsAdam]

Hi all. I'm interested in improving my brakes, although I'm not sure if they need improving. I'll explain.

I have 13" 1993 Mustang cobra R brakes up front (calipers were rebuilt last year and system bled) and the FFR 11.65" rear brakes. I think the master cylinder is OEM Ford. It's non-power.

I didn't build the car. I have never owned a car without power brakes so I don't know what is considered normal/good.

The pedal requires a good amount effort. The car stops pretty well, but I'm not sure if the brakes can be better and/or be set up to require less pedal effort.

Suggestions?
