I just bled all four brake calipers and my brake pedal is hard when the car is off and pumped up. But, when I start my car up my pedal is spongy. What could be the cause of this. Could it. Be my brake booster or my abs box I talked to a auto part manager he said it could be the abs box. But if it is how can I bleed it there is no bleeder screw on it I need help bad.
