When I leave my house brakes are normal after a very short time, I'd say 3-5 minutes the brakes pedal gets very firm and the front right brakes are sticking. I have replaced the brake pads, the caliper, and the brake hose. I'm at a loss, I have no idea what to do next. please help.

This is common when the brake master cylinder needs to be replaced or the push rod in the brake booster is adjusted out too far. To check if the push rod from the booster is the problem slimly loosen the brake master mounting bolts two turns to see if the left front wheel starts to turn, if so, remove the master, (you can keep the lines connected) and turn the push rod adjuster in two turns and it should fix the problem. Let us know what happens and please upload pictures or videos of the problem.

The front brakes are dragging left and right side. I'm not sure what could cause both sides to drag. Help

Did you read my first response? Please loosen the brake master mounting bolts three turns after the car is jacked up in the front to see if the wheels turn.
