| Post subject: | Brake System Warning Light |
1970 Dart Swinger. Front disc, rear drum. The brake system warning light on the dash has just started to flicker as I'm cruising down the road. It occurs when I hit bumps in the road. I don't have access to any FSM info at the moment, and was wondering what this light is measuring and where the sensor is. The fluid level in the MC seems consistent. I don't drive this car a lot and have noticed after extended periods (1-3 months) of sitting, the first few times I brake there is a bit of a shudder in the front end. I always attributed that to some minor surface rust build up on the rotors as it would go away after some around town driving. Any thoughts would be appreciated. RC |

"flashes on bumps" "flickers while driving" means the wire is grounding out somewhere intermittently. That light serves two purposes: It comes on when the handbrake is applied, and it lights up if a pressure imbalance is detected in the brake hydraulics. The former function is handled by a "refrigerator door" type switch at the leading end of the handbrake shaft under the dash. The latter is handled by a contact and sliding shuttle in the brass metering block you will find if you follow the two brake fluid pipes downward from where they leave the master cylinder. |

Thanks Dan. I thought it might be something like that, but am glad for the second opinion. |
