I have a 97 contour sport with the 2.0 liter, everything standard with disc front drum rear brakes. Every once in a while, maybe every other week, the brake pedal gets hard for a stop or two. Pedal never goes to floor. It will pump up hard with engine off and then when I start it, the pedal will depress to its normal height. I am thinking either an intermittened vaccumm leak in the booster or hanging caliper or wheel cylinder. Am I barking up the wrong tree? And then how to I tell which wheel cyclinder of caliper is sticking?
Thanks.

Bleed the brake system....check out the FAQ's if you need some guidance. Brake fluid is hydroscopic (picks up water) so maybe your fluid has been contaminated/degraded over time.

I'm more inclined to think it is a vacuum related problem than a hydraulic problem. Look hard at the booster.

My old Tempo had a problem almost similar to that. It would have a spongy pedal, but catch and be hard every once in awhile. I think it prolly was a fluid problem, but I had the shoes replaced in the back, and the rotors and pads replaced up front, and it went away. I would try a fluid flush/bleed first.

first check the booster and check the lines for cracks that could be leaking during certain pressure or on turns but not under normal standstill. if nothing have the fluid flushed, places around here that will flush a brake system usually refill and bleed for you.

I just remembered that i have seen a few Taursus with collapsed vacuum lines to the booster that acted exactly as you have described. Look over the vacuum lines for any kinks or other things that can restrict vacuum.
