V8 two wheel drive automatic 60,000 miles.

I have the yellow warning sign on the dashboard that the parking brake is malfunctioning.

No other problems exist with the car, electrical, warning icons, etc.

Is this a matter of tightening the parking brake cable, or possibly rear brake pads need replacement?

Thank you.

The parking brake shoes are adjusted through one of the wheel bolt holes-E36 models shown, E30 similar. The parking brake may be tight.or there is a binding on the parking brake system.

The star wheel adjuster is moved by pivoting the adjustment tool-E36 models shown, E30 similar

But I am not sure you understood my question. The "malfunctioning brake" light is illuminated, but there is no binding. Simply put, the parking brake will not engage when I press the electronic parking brake button. Is this due to worn parking brake pads? Or shall I try to adjust them? Could this be an electrical problem? A fuse burned out? I can check all, but thought maybe to ask first as this may be a common problem/function of this model. Thanks in advance.

The parking brake is electrically actuated and may need service, it will need to be checked by a BMW knowledgeable technician who can scan the car and deliver the diagnosis. It is not possible for me to pinpoint the issue from here. Do you have a repair facility that has been servicing the car?

That is correct Dr. Hagerty, a continually illuminated brake warning light may be cause by a grounded wire to the parking brake switch, or a continually closed parking brake switch, or low fluid level one section of the master cylinder reservoir.
follow what Dr. Hagerty, take it to a BMW facility. you have a nice car there.

The light is yellowish instead of red as it is when engaged.
