I trying to finish my 5 lug disc conversion and now need some help. I want to keep my booster and lines but what master cylinder do I need? I already have a proportional valve but I think I will need a master cylinder to achieve good pedal feel. I already have this kit Mustang 94-04 Rear Axle Caliper Bracket Kit by Ford Racing at LRS - Same Day Shipping! , so will I just need to pick up so caliper and pads?
