PARKING BRAKE MALFUNCTION

2002 BMW 745

Brakes problem
2002 BMW 745 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'm 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.

Thanx 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.
