The driver's side catches more than the passenger side. The master cylinder, calipers on both sides and the flex lines have all been replaced.

Hello,

This could be due to ABS system malfunctioning.
It could be faulty ABS sensor on one of the wheels that triggering the ABS to lock up. It could also be due to an overheating electronic brake control module (EBCM). The EBCM controls the brake function for this vehicle.

Is your ABS light illuminated? If so, getting is scanned can help the with the diagnostics.

Here is a helpful video on how to scan for ABS codes:
