So I replaced the original powersteering side cause of every seal leaking and going through quarts of fluid!

I order one from autozone(nice piece) all the numbers matched up to the original one!

Now my problem is the pedal feels normal as it did before.but as I'm driving and hitting the brakes the pedal gets harder and harder until the brakes are completely locked up! (Melted my hub cap) I let the car sit for 15min,and after that the brakes are fine? I don't understand! Pedal goes back to normal and brakes work good until I drive and keep stoping? Any ideas

sticking caliper?
old brake hoses?
master cylinder new?
the proportioning valve on the frame in good condition?
