Question on brake rotors

I'm slowly tackling my Dad's TR4A IRS. Some history, very little has been changed since he was the 2nd owner. It's currently at 58,500 miles and a true gem in my eyes.

There are a few things that need tackling, but for now the main thing I'm seeing is front brakes. The last time I took it out for a spin the brake squeal was embarrassing. I was thinking a quick brake pad replacement, but then took a look at the rotors, which are probably original or 40+ years old. There is a substantial amount of pitting along the outer edges (probably 3/8" in from the outer edge). What should I do here.. resurface? Throw some $$ for new rotors? I'm thinking the later option is the correct way to go. Any thoughts?

Thanks in advance for the advice all.

Goodparts sells stock rotors for $69 per pair. I'd go for those and spend some on reconditioning the callipers and putting in some new pads.

Car that won't go is bad. Car that won't stop is terrifying.
 
Consider replacing the flexible hoses too. After as little as 6 years they can begin to collapse internally, or even let go completely due to rubber compound degradation.

It's not a split system so failure of any hose means total loss of brakes.

A little rust on the rotors won't hurt anything. If it's where the pads don't touch it can't hurt, and if the pads touch it they will polish away the rust instantly. I'd guess you are looking at the area where the pads don't touch.

As long as squealing is the only problem, I'd leave the rotors alone.

Take a fairly coarse file (or even sandpaper) and cut a slight bevel on the leading edge of the pads (so the corner isn't in contact with the rotor). If that doesn't work, I'd suggest some of the "cut to size" anti-squeal shims that go between the back of the pad and the piston. They worked a treat on my TR3A and only cost about $5 at FLAPS.
