Brakes Issue

[mmcporter]

I am looking at a 1972 Skylark that was stored for several years. The car is in good shape but has 2 issues. This post is a question about the brakes. The car has power front disc brakes. While driving the car, the brake warning light is coming on intermittently on the dash. The master cylinder is a little rusty on the outside, but doesn't look too bad. Inside, the fluid is full. The car seems to stop OK, but I thought I felt a little fade when driving it (maybe psychological?). Any thoughts on what could be causing this?

mmcporter,
I just happen to be tooling around with a '78 buick regal that was stored for a while --had a similar problem--I took out old brake fluid and re-bleed all the brakes.There was some condensate in the old fluid.------Just a starting point good luck-------------JoeG
