Taurus Electronic Parking Brake Failure

Sounds like a common issue with those electronic parking brakes. Before you go tearing into the calliper, have you checked the brake switch itself? Sometimes a faulty switch can throw off the whole system and cause those symptoms. Also, is the brake control module getting power? Might be a fuse or a wiring issue causing the problem. I had a similar brake fault on my old Mondeo, and it turned out to be a corroded connector to the control module. Worth a look before assuming the worst.

Thanks for the quick reply. Where is the brake switch located, and how do I test it? Also, how do I check if the brake control module is getting power, and where is that located?

The brake switch is usually near the brake pedal assembly. You can test it with a multimeter to see if it's sending the correct signal when the pedal is pressed. As for the brake control module, its location varies but is often behind the glove box or under the center console. You can check for power using a multimeter at the module's power connector. Look up the wiring diagram for your specific Taurus model to identify the correct pins. Honestly, if you're not comfortable with electrical testing, it might be best to take it to a workshop. A faulty module or wiring can be tricky to diagnose without the right tools and knowledge. I ended up doing that when I couldn't find the issue myself and my local mechanic found it right away. Replacing the motor in the calliper can cost you around 505€.

I appreciate the guidance. Given the complexities, I'm taking it to a technician for diagnosis and repair. Your insights helped me understand what might be going on. The estimated repair cost is about what you said. Thanks again.
