Why does the parking brake warning light on my 1973 Buick Centurion not turn off when car is running ?
Since yesterday, the red parking brake warning light within the instrument cluster continues glowing when the engine is running / while driving. The parking brake was fully released and the brakes seem to operate properly. Is this rather an electro-mechanical issue (e.g. sticking switch) or should I have my brake system professionally checked ?
Not sure on your car, but there is usually a sensor in the brake reservoir that when the brake fluid gets low the parking brake light will also come on. Make sure it is at the MAX level, if not add and find out where the leak is.
I don't know if the early cars had the fluid level sensor...... You problem is probably the switch on the parking brake....If you look at the parking brake assembly you will see some wires going to it....follow the wires to the connector. If you unplug the connector and the problem goes away it is the switch
