Brake Problem

[jar2187]

How come when I unplug the connector on the side of the master cylinder my e-brake light goes out on the dash. When I plug it back in it turns back on. What would cause this? Btw my e-brake light and rear antilock light are on.

Just means that the sensor is bad on the master cylinder. Easy replacement.

I just replaced the master cylinder. My pedal still doesnt feel right I can push it to the floor, could this be because of the rear proprotioning valve?
