If your planning to keep this car. Not knowing history of maintenance. Personally I would replace the calipers with stock, replace rotors, brake lines and rebuild master. If one caliper has gone bad chances are the others might fail soon. And when your done you’ll know exactly what shape your brakes are in.

Long story short. After installing a rebuilt engine and going on a lengthy tuning drive. Hitting triple digit speeds. It was fun. But, when I got home it hit me that my brakes and suspension where still over 40 yrs old. Ordered parts the next day.

2 cents worth.
