Hello.

Yesterday i went out with my Cougar to a car meeting here in the South of Sweden.
Suddenly i lost my brakes, not totally but i have to step 3 times on the brakepedal to get close to normal brake power.
No missing brake fluid,, no leaks.
I suspect that the master brake cylinder is gone.
Guess this is such things that happens to a car that sits in a garage for 20y.

Sounds like you are right, the master cylinder fluid by-pass. If you can pump pedal and get brakes, and then it leaks off while holding pressure on the pedal, it's the master cylinder.

Just put a new one in mine last week (70 XR7), same syptoms as you described...had to tap it every time before breaking...but after holding pressure (like at a stop light, they would fade)...new one from Advanced Auto, $20 and a $5 core charge. Be sure to "bench bleed" it before installing.
