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) |

I have the same concern, have left the one wire loose. I think the switch is bad. Going to replace it with a 2 pole switch.
