Rebuilding yourself will probably do the trick and the kits are not much $$$. Might be a good investment to get bleeder valves, new hoses, and the short hard brake lines all at the same time. Probably less than $100 in parts total. (For the fronts)
Getting the lines will make it much easier to demo and you'll know you should be able to do everything in one shot.

Regardless of the milage time take it's toll on the rubber and in terms of rusting things together.

1st step is to push the pedal 1/2 way down and prop something against it. This closed the valve on the Master cylinder that goes to the resiorvor to keep it from draining and gettin air in the lines. If you are goung to scrap the old lines than cut them with tin snips and you can put a box wrench on the fittings and thus not round them off.

Good luck!
If you want to stop by we can do the calipers in my shop.
