Question about Chevrolet Blazer
Sounds like a master cylinder failure. Were you able to pump the brakes and build up pressure? If so, it sounds like an internal leak in the master cylinder, perhaps in the diaphragm inside. If that diaphragm allows fluid past it (through a pinhole, say), pushing the pedal will allow the plunger inside the MC to push straight in without actually moving the fluid through the lines, out to the brakes.
