Air Brake Antilock problems of the 1997 Ford F-150

I have had this vehicle repaired numerous times under factory warranty, problem has worsened. Three near accidents, could have injured or even killed other drivers and/or passengers. I have complained many times. I can't seem to get anything done about it. If an accident occurs, I will take the proper legal steps to the fullest extent. I feel that this problem needs to be resolved in the very near future so an accident does not occur. At the present time, I am currently researching the florida "lemon law" I will take all neccesary steps to conclude this problem. Have a great day. Please contact me.

Rear brakes lock and front do not when pedal is slammed.
