Changed a flat tire? Did you over tighten some of the lug nuts or leave some loose?

No the lug nuts are all torque spec it wasn't making this doing this before I change the tire any help for any answers or helpful


If it was a rear wheel your truck has rear abs may have ripped a wire

And just to let you know I've both drums and shoes . Would it be something in my dump valve or proportioning valve


Oil on the disk?


I'm really leaning towards ABS they don't throw codes very often. Don't thinks it a valve brakes stop working or pedal has major travel if bypassing. Especially all you did was changed a flat tire....was the tire shredded?


Was it a rear tire?

Yup rear passenger, and it was not shredded, had a nail went flat overnight


You could disconnect the abs fuse/ relay the test drive easiest try atleast


Inspected around that wheel the wire may have just been pinched not always cut
