Here are a couple of things I'd suggest:
1) Replace all of the flex brake hoses even if they look ok... They deteriorate from the inside out.
2) Rebuild the calipers... After 28 years and a lack of brake fluid flushes, the amount of "glorp" inside will impact the small passages inside the calipers and will cause uneven or no application of the pads to the braking surface. The caliper rebuild kit includes the appropriate new rubber seals and stuff.
3) Replace the brake fluid in the system by bleeding the brakes until you get clear fluid out of the bleeder nipples.

We did all of this and my car stops on a "dime and gives 9 cents change"!

Don't cheap out on this... You're life, your passengers and potentially anyone who may be contacted by the car with bad brakes is on the line!
