The brakes engage on their own after about ten minutes of driving?

I recently had my brakes done. When I say done, I mean rotors, pads, calipers, and master cylinder; everything you can do. Now the brakes engage on their own after about ten minutes of driving. Left to sit for an hour they disengage, and I can drive a varying amount. I also replaced the hoses. Anything you can do to shed light on this would be great. Thank you

Hi,

There is a drag on them causing them to get hot. Brake fluid expands when it gets hot, so the more you drive, the hotter it will get and the harder they apply.

Craw under the dash and check to make sure the brake pedal is fully releasing. There is a clevis pin that attaches the pedal to the pushrod. Disconnect it to see if the pedal is fully released. I have a feeling something is out of adjustment. Don't drive it with the clevis disconnected. You will lose the brakes.

See pic below and let me know what you find.
