I was pulling out of my parking lot at work and brakes suddenly locked up. It felt like they were dragging the 5 miles or so on the way home. When I got home they smelled hot. After they cooled, I checked the pads and rotors and they seem fine. Now it feels like I am "loosing pedal" and there are no leaks. Could this be a master Cylinder or ABS problem?

This happens when the brake booster push rod is adjusted out too far which does no allow the brake master to return fully holding the brakes on . To confirm the issue loosen the brake master mounting bolts 3 turns to see if the car starts to roll again, if so remove the master and adjust the booster push rod inward. Also a brake flex hose can come apart internally causing a short of check valve in the system but this is usually isolated to one brake either front or rear.
