After driving car about fifteen minutes brakes lock up. I have replaced ABS pump. Two front calipers. And master cylinder still locks up. What strange is that it locks up even without driving it after car warms up for say fifteen minutes while parked I tried moving it and it was locked up already. I shut off let car cool down and then it unlocks.

Hello,

It sounds like the master cylinder push rod needs to be adjusted inward. To confirm when the brakes are lock please loosen the master cylinder mounting bolts allowing the master to slide forward slightly, if the brake unlock remove the master and wind the push rod adjustment inward. Please let me know what happens.
