All breaks seized after 5 mins of driving

Hello,

This could be due to a bad modulator unit for the ABS system.
That unit controls brake fluid pressure for all the wheels. It could have a seized valve and keeping the wheels locked.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
