Try checking to make sure your parking break is all the way up. I have a 97 suburban and every now and then someone brushes the parking break pedal just enough to make the light come on.

if brakes work ok leave well alone ,this sounds like an electrical fault that big money to repair.At the end of the day the brakes are failsafe manually operated

you have an abs fault. have your abs system scanned for codes.

your base brakes will continue to function normally

check common rail. maybe the problem concerns with a lack of ground (car chassis), and the return path is made through the other bulbs.
Use a 400-grade sand paper to clean the contacts and the metal part of the bulbs.

hi check your charging system make sure it is charging [belts not broken] and most important check your brake fliud level if its low the waning light will come on or the parking brake light may be faulty as these lights on the dash should not be on the same circiut excect if there is a short in the grounding circiut on the dash yates210456

MSchmdt1702 I just fix this problem. I had to replace the switch that the turn signal handle plugs into. The switch cost about 450 from the dealer. I'm sorry I can not remember what the exact name of the part. If I find it I will post it
