the other day my wife comes home and says that she lost her brakes on her trailblazer but now they were fine, she said it happened twice within a 3 day period, she said the pedal went to the floor and nothing happened, and then everything was fine. I went and drove it and the brakes worked fine, a little more pedal travel than what I'm used to In my truck but they worked, im wondering could there be air trapped somewhere? Or does it sound like a master cylinder problem? Would I be wasting my time to bleed them or should I just start with the master cylinder? I do know the front drivers side caliper was replaced by the previous owner because when I changed the hub assembly I noticed it had writing on it from a salvage yard
