The brake switch on my master cylinder has 2 wires. I didn't see any reset button. When I unplug the brown/white signal wire going to the brake light in the gauge. The brake light will respond accordingly to the hand brake and go out. Before it would stay lit all the time regardless if the handbrake was applied or released.

So the question is how do you reset the brake switch or do I need to bleed the brakes ??

The brake light was working fine until the transport company moved my vehicle. I think the driver may have applied the brakes too hard maybe (IMG:style_emoticons/default/confused24.gif)

Let me know you thoughts.

Thanks everyone ! (IMG:style_emoticons/default/driving.gif)

Just reworked my entire brake system with help from PMB Performance. Replaced the master cylinder as well. I too had the persistent "brake" light flashing/alarm and didn't know how to remedy the situation. Was told by Eric at PMB that I needed to reset the switch. Since I had the car up on stands I could easily get to the master cylinder again. Removed the boot protecting the two electrical wires. Adjacent to the two electrical posts is the switch, not really a switch since all you have to do is push it in. It is only a protrudence of plastic and not easily recognized as a switch. Push on it while the key is turned to the on position. You will hear the cessation of the brake alarm. The brake light will stop blinking. Easy. I've had to do this twice now once with the car on the ground.
