This is an odd issue so we need to get a few more details to fully understand.
If you go start the vehicle and never touch the brake pedal, do the brakes lock up? I assume they do not. So does that mean they are applying and not releasing the first time you are pressing the pedal?
If this is the case, are you sure it is all four wheels? Let's lift the vehicle and make sure it is all the wheels and if not which ones are not releasing?
I am thinking this is one of two issues depending on these questions. First if it is all the wheels then the issue has to be something that affects all the tires which would be the master cylinder.
If it is just one or two wheels then I suspect we have an issue with the rubber brake line that is swelling and not allowing the caliper to release.
Let us know what you find with this and we can go from there. Thanks
