2005 Hyundai Accent Brakes have locked up while driving and will stay that until the car is stopped and sits for a while. I have replaced the front brake calipers, pads, hoses, and turned rotors. Brakes are still locking up. What is my next step.
Do you
have the same problem?

When it happens again, crack open the steel lines at the master cylinder to see if the brakes release. If they do, suspect the fluid is contaminated with petroleum product. That will cause all rubber parts to swell and the expanded lip seals will prevent the brake fluid from going through the return ports to the reservoir. You might also loosen the master cylinder mounting bolts two turns each and pull it forward. If that works, the push rod is adjusted too long, but that wouldn't happen on its own unless someone was in there or replaced the master cylinder with one that is a little different.

If any repairs was done at the pedal, check the pedal to booster push rod clearance. If there is insufficient clarance, the master cylinder piston would not return fully for fluids to return when pedal is released. That would result in the brakes seizing when the fluids heats up.

Is only specific wheel locking up or both front/rear in tandem?

Well first off, its really not the brakes. I went through this mess myself, just finished it. Its the bearing in the hub assembly. Makes it sound like the brakes are locking up. But in fact, the bearing went out. Pull the hub assembly, take the hub to a machine shop and have it pressed out, run get a new bearing, go back to the machine shop so they can press it back in. Then slap it all back together. Omg, I was so relieved when it stoped locking up

OMG! I had the exact same problem! I replaced the rotors, pads, calipers, and it seemed to fix the breaking issues I was having, but now my inner pads are wearing bad and my car shimmies when breaking. I'm at a loss what to do.
I have a 2004 Sonata V6
