Hello List, Another problem which is kind of scary, I seem to be losing brake pressure when I am at a stop light or pulling out of my driveway. Pressure I mean the car is stopped then I feel the pedal move, all the way down to the floor, I pump it and the pressure is back. I would think Master cylinder etc. but here is the funny part. It happens only sometimes (haven't seen a pattern yet), the day could be super hot or cold doesn't matter, there is no leaking brake fluid anywhere, the fluid is always full. Someone once told me that I had air in my system, maybe but that's kind of weird. Or an internally bleeding brake master cylinder, so I can't see the leak? I first noticed this during a parade and we were going stop and go up a steep incline for a while and then stop and go all the way down, and that's when I noticed it. Anyone had a similar incident before? Suggestions? Thanks in advance Felix [Non-text portions of this message have been removed]
