Thanks. That's pretty much the whole system. The car is well mantained and only has 63k on it and the breakes work super other than the few times the light comes on and the pedal gets hard. The brakes grab hard and does not create any pull. The issue with the on.off feeling after sitting might be an easy fix. I just wanted to know if there is a certain spot in the system that often can cause this. I don't feel like taking the whole system apart so I was hoping you could lead me to where to start looking. Thanks
