After sitting for 30 years, the brake hoses and wheel cylinders and the master cylinder are going to be toast. Replace them all and carefully inspect all steel lines for rust. If the brake linings are still serviceable, you can probably reuse those as well as the springs and retainers.
www.rockauto.com has most of the vintage brake parts you will need. If they do not have them, try
www.manciniracing.com they stock a lot of the hoses.
www.jcwhitney.com also has some of the vintage brake parts. You should also pull the rear axles and repack and re-seal the bearings, same also true for the front wheel bearings. If you need new brake linings, try to find a supplier of either Wagner or Raybestos linings. OEM linings are also good.
This would be a good time to consider converting the brake system to use DOT 5 brake fluid if the car is going to spend winters idle. You will have new hoses, cylinders and a new master which makes this the perfect time to do this. Dot 5 does not corrode as readily and if properly done will last for many years.
A thirty year down time car is going to need a lot of work to get it road worthy. Tires need to be replaced as do all heater hoses, radiator hoses and belts. If this vehicle has power brakes, most likely fluid has leaked into the booster and it will need to be rebuilt as well. Also do a complete tune up. If the car sat with coolant in it for 30 years, most likely you are going to have corrosion issues with the radiator and heater core also. If the fuel tank had fuel in it, it is most likely junk as well, pull the tank and at least have it cleaned prior to trying to start the vehicle. You should change the engine oil, transmission oil and rear end oil as part of the prep work. Replace all rubber fuel lines as well since they do not play well with today's blended gasoline. These things will give you a good start.
