Brake Antilock Control Unit/module problems of the 1999 Chevrolet K2500

(1)brake pedal goes to floor slowly (bleeding back through master cylinder system) and pulsation from front brakes at 5 mph: brakes release and can not stop. (2)can not stop in emergency situation or in foul weather. (3)replaced master cylinder and disconnect ebcm (electronic brake control modual power lead. Note: upon doing research from NHTSA website found various complaints from consumers with similar problems. I was disappointed that dealors concluded removing the fuse. In my case, if you remove the 60 ampere fuse the power windows and hvac system become inoperative! I own a 1999 Chevrolet K2500 pickup with 56,500 miles. Additionally, I have two CO-workers who purchased 2001 k1500's that have similar abs problems. Luckily, they are under warranty.
