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) |

im bringing up this old thread because im having a few issues with a blinking red light in the dash above the fuel level.
ive been banging my head against the wall on this one. i have a 1973 1.7 and i have a 2 pole brake switch that does not have a reset. i have two wires plugged into it and if i pull them out it makes no difference. so my fasten seatbelt light is on when the brake is down or up...its real iintermittent as im moving the brake up and down. but it goes out when buckled. on the back of the cluster, if i pull the "black/white stripe/green wrap stripe" wire, the blinking stops and the fasten seatbelt light continues to work until buckled. any ideas here? i did recently replace the soft lines and one hard line and bleed the brakes. thanks for any help, just trying to get the electrical sorted out before attempting to get the motor in there. |

The switch for the parking brake is down on the floor under the parking brake lever. Fills with garbage over the years. Pull the driver seat and clean it up... |
