Hi mate i did this on my old fiesta and it was featured in fast ford some years ago, probably 2002/3 iirc....... anyway 4x4 discs are ok to use as long as the caliper carrier is spaced from the hub by 5mm. As for the braided hoses i used fiesta ones and had no problems with them. Just make sure they dont rub on the inner arch at all

Mart.
