Stock FSVT are not four piston! Someones pulling your leg.
The aftermarket kits such as mine are, but then you'd just be using the one for the Contour anyhow.
None of the rear kits for the Foucs are four piston either. Hardly worth the parts to do it. E brake cables on the Focus have to be changed IF you start with a drum car and chang to disc. No compatability between the rear brake parts on both of these cars that I can see. Fronts yes, with some work that has been talked about before.
