HYUNDAI ENTOURAGE BRAKE

If A Dual Circuit System Had A Leak On One Of Its Circuits, Does The Brake Fluid All Leak Out After Repeated Pumping?

Do You Know What Type Of Tool Is Required To Remove The Caliper And Caliper Mount Bolts For This Vehicle? Thanks

There Seems To Be Something Blocking Removal After I Have Removed The Two Caliper Bolts.
