Front left brake caliper will not release?

So, the dragging noise, can you jack up the front of the truck and spin the front wheel in question? If so, the caliper is releasing, and I would check the dust shield on the back side of the rotor because they can contact the rotor and make a dragging sound. Let us know what happens and please upload videos of the problem so we can see what's going on. I assume the problem started after the brake job was done?

No, I checked the dust shield. The only way the caliper releases if the bleeder is opened.

It actually starts to get hot and you can smell it on that one wheel.

There is only one thing left I can think of which is the ABS control valve. You said you replaced the flex brake hose, correct?



Do me a favor and when the brake is locked up try loosening the master cylinder mounting bolts 3 turns to see if the caliper releases. If not, I would replace the ABS control valve, there must be something stuck in the right front control valve. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Okay, thanks! I will try that and let you know.

Ok thanks! I will try that and let you know

Please do, have a good weekend.

I just loosened the master cylinder bolts and wheel freed up.

So, that only loosened the wheel when truck was off. I went for a drive and still same dragging on that side. Also got this come on the dash for first time. Then it went away.

Okay, let's do a scan for the ABS system, here is a guide to help:

Please go over this guide and get back to us.

So an OBD 2 scanner?

It is OBD2 but it can do the ABS system, you can use a CAN scanner as well. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Please go over this guide and get back to us.

Here are the codes.

Those codes should not cause the caliper to not release. When the caliper is locked up can you open the bleeder on the caliper to see if it releases?

What would cause these? Plus auto park disabled comes on after driving for 5 minutes. Traction control light and also check engine?

Okay we are getting closer, also did the wheel turn when you replace the bleeder?

code C1082 this code specifically refers to a problem detected in the "Brake Fluid Pressure Sensor 'A' Circuit,"

So, this sensor is inside the ABS control module which sounds like it is bad, I would get a new or used unit and install it, here are the instructions on how to do so. Once installed, clear all codes.

Check out the images (below). Please let us know what happens.

I just replaced the ABS pump and module.

It’s all the same messages as before except for the check engine light as before I changed the pump and module. If I go through wet grass the ABS comes on. I bought the pump from 50 state auto. It was used. Had 27,000 miles. They said they test the pumps. I also gave them the VIN to program it.

Does the wheel spin if you open the bleeder?

Yes.

I would replace the front brake caliper flex hose.

Did that already also.

The only thing left is the ABS module.

So do you think that one I just put in is bad?

Run the ABS codes to see what it says.

Please go over this guide and get back to us.

Okay, I will. I have a buddy with a scanner that did it last time.
