TESTING WARNING LIGHT SYSTEM
If the parking brake light is connected into the service brake warning light system, the brake warning light will flash only when the parking brake is
applied with the ignition turned ON. The same light will also glow should one of the two service brake systems fail when the brake pedal is applied.
To test the system, turn the ignition on and apply the parking brake. If the lamp fails to light, inspect for a burned out bulb, disconnected socket, a broken
or disconnected wire at the switch.
Above is an exterior view of one of these switches. They are usually mounted on the left frame side rail or on the brake pedal bracket.
To test the brake warning system, raise the car and open a wheel bleeder valve while a helper depresses the brake pedal and observes the warning light
on the instrument panel. If the bulb fails to light, inspect for a burned out bulb, disconnected socket, or a broken or disconnected wire at the switch. If the
bulb is not burned out, and the wire continuity is proven, replace the brake warning switch.
