Angry Parking Brake
I have a 2013 Mercedes ML350 and I’m getting the message “Parking Brake See Operator Manual” and the yellow parking brake light stays on also. I stopped using my parking brake because the left rear brake was getting stuck and won’t disengage so I would have to play with the parking brake switch to get it to unlock.

I replaced the parking Brake switch but the lights still stay on. I did a computer diagnostic and got 2 faults with the Parking Brake.

1. The position of component Electric Parking Brake is Implausible

2. The left brake caliper is faulty. An open circuit exists.

Can someone tell me if this could be a faulty sensor on the left rear wheel or something else?

You are on the wrong forum.

The problem is not your caliper. It is with the parking brake shoes. One or both of them have detached.

Here are the procedures, especially the last PDF.

After you remove the caliper, you must adjust the parking brake shoes so they contract. Turn the adjusting wheel in one way and spin the rotor and see if it gets tighter. If it does then spin the wheel in the opposite direction.

Took off the caliper this past weekend and saw I don't have parking brake shoes! I think I might have to buy a new caliper.

All cars have parking brake shoes. You have to remove the rotor to see them.

Why did you order shoes when you did not remove the rotor to see if they were damaged?
