My brakes have locked up, the VSC and ABS light are both lit up, I reeased the front brakeson the left hand side using the bleeder screw, the front brakes released, and when I went to try to drive forward they had locked upi again. Meanwhile, there is nothing there when I press the brake pedal. The rear brakes pads were replaced 2 days ago, and the front about a month ago. When I first noticed something differant, it was that the brake pedal travel was very short, and when I come to slow down for a stop the brake pedal seemed like a brick wall, and the brakes were not doing much at all, I let off the brake pedal and pressed it again, rock hard for a moment and then went to the floor, and from that point on, no pedal whatsoever. Could this be a sensor for the VSC, or ABS? Or could it be something differant?

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
