Usually on a brake system with adjustable bias front/rear---if you have a obvious problem with a wheel---the fault is at the other end of the car---in this case, the rears aren't doing there job and the driver just pushes down on the pedal to stop the car and the brake that is working correctly will lock up and get the blame for something wrong with it-- in this application, the bias is too much toward the front, the rears aren't contributing there portion of the stop force and because of a heavy left front weight causes the right front to lock up.
