I am trying to comvert my 71 torino to rear discs. I was going to use the explorer disc brake kit from ford performance parts but they said it wont fit my car. which one should I go with the SS brakes or a swap that uses lincon rotors and cadillac calipers. Help please. Also I want to add a power master cylinder but do I need to change the pedal or not. I have seen a master cylinder somewhere were the porpotioning valve was mounted under it on a bracket and it was already plumbed you just have to hook up one to the front brakes and one to the rear. I can;t remeber where I saw it does anyone know?
