Hi, I have a 95 NIssan Pickup two wheel drive, four cylinder. I recently replaced a broken brakeline and bled the system, but no pedal. I tried gravity bleeding the system with all bleeders open with the truck level. Then I pressure bled the system again to no avail. This morning I replaced the master cylinder with a reman. I bled the cylinder on the bench and then installed it, gravity bled the system, then pressure bled, still no pedal. When the truck is not running I can pump up a good pedal. If I take my foot off for a minute, the pedal is dead again. When the truck is running, there is absolutely no pedal. I can't imagine that there is air in the lines because I have gone through two large bottles of brake fluid and bled the system at least six times. Also, when I pump the pedal and crack the bleeder, the fluid comes out with force with no air sputters. There aren't any leaks, I checked all the wheel cylinders and lines. No dripping anywhere. Can anyone please help me? I'm desperate. Thanks in advance.
have the same problem?
