Front Brake Lockup?

Front Brake Lockup?
Hi all, did a search, didn't find my exact situation (i think). So here it is:
On initial start, car drives fine, nothing feels funny about the brakes. After a little while of driving, the pedal begins to feel stiff and you can notice some resistance while accelerating. After this begins, it will get to the point where you can barely push the brake pedal (because it is stiff), and the car will not move forward while pushing the gas pedal, as the engine races.
The rotors get too hot to touch and even sizzle water if you put it on there.
I replaced both front calipers and the driver font brake hose to the caliper.
After this, driving the car on a slightly longer than normal trip (for a days commute), the front brakes locked up again. I opened the bleeders and fluid came out of the driver caliper with such force as if someone was stepping on the pedal. Then the passenger caliper bleeder bled no fluid. I was able to drive the car after this.
What is keeping this extra pressure that slowly builds up on my brakes? Could the pushrod need adjustment? Do I just need a new booster/master? Any ideas are appreciated. Thanks!

Re: Front Brake Lockup?
Sounds like a leak in the master cylinder not allowing the return spring to come back and relieve pressure...
May also want to check your pads and rotors to make sure they are not glazed/warped from the heat... once you get it fixed.
