1998 Ford Explorer 6 cyl Four Wheel Drive Automatic 143750 miles
I had a damaged front caliper driver side and all the brake fluid leaked. I just finished replacing front rotors, calipers, and brake pads for both sides. After installing the new parts, I bled the brakes both sides. If you pump brake paddel once or twice when engine is turned off, the paddel gets hard as it would be under normal circusmatance. But, when engine is running and you press the brake paddel, it sinks to the floor without any pressure. The vehicle doesn't stop and brakes don't work. I have bled the brakes twice and there is not air in the system (as I know). What am I doing wrong? I have changed master cylinder and brake calipers on other vehicles (Nissan Maxima 1987, Pontiac Sunbird 1983) before without any problems. Can you please help me? Thanks.
