Last week I started loseing hydrolic fluid like crazy. I found the leak on the pump, it was an O-ring that gave up, again. I figured I got lucky, wrong. Now the brake peddle is slowly moveing towards the floor and will go all the way down if I let it. I changed the pressure accumulator less than a year ago. I can't believe that's the problem again. Any advice. Ron

 

My bet would be the master cylinder. I have had two instances of the sinking peddle and in both cases it was the master cylinder.

 

I found it, it was a brake line in the rear. Your right about the master it went about 10 months ago. I replaced it and the bomb, that seems to go bad about every two to three years. Thanks alot, Ron
