I was going to ask what part number your brake master cylinder and servo have on them to see whether you are running an S1 setup (or whether I am!). Are the original servo and MC in the car?

My car has 4x4 Cosworth brakes with S2 rear drums on what I assume to be a stock MC and servo with braided lines. In all honest the car stops fine and right on the button. No long pedal and for Escort standards it actually comes to a halt! Remember that the Cosworth brakes have a 60mm piston as did the S2 RS Turbo calipers, so the pedal travel will not as long as you think. Going to a bigger master cylinder in some cases can actually reduce braking power but give you a nicer pedal.

I noticed this going from my Wilwoods TBH. Many suggested for me to go with a smaller master cylinder to get around the issue ; the pistons in my Wilwoods were 31mm, way smaller than the Cosworth item even with the surface area of 2 pistons combined.
