I noticed smoke coming from the brake light switch that is threaded to the power brake booster. I unplugged the two wires going to the switch and the lights went out. The brake lights were on since yesterday and had drained my battery. There is no oil puddles underneath. The reservoir is full. The brake pedal returns to the top position very slowly with the car running or off. It makes a squeaking sound. The pedal is stiff but travels to the floor with the car off and soft and spongy with the car running. I am wondering if the brake booster has failed. I'm not sure where to start. Thanks to all that reply.
