Brake Problems
 

My dad has an 01 ecll everything works fine and the fluid is full. The problem is when you brake hard its like the ABS unlocks and the braking power is terrible. Someone said something about a block that could have air in it but the couldnt tell me exactly what or where it was. i assume it to be a distribution block but im now sure. Anyone ever heard or know anything about this? Any help would be awesome.
