I've replaced the master cylinder with a stock and now a NBS version, all 4 brake calipers [disk rears] along with wheel cylinders back when the rear was drum, and all the hoses with steel braided lines. I've never needed a special tool. I've never cycled the ABS pump either. Master cylinders do go bad on occasion remember.
