So we've been having issues with the breaks. We installed two front calipers and new rotors. We can't seem to bleed the breaks, we have plenty of fluid going through but no pressure. We also installed and bench bled a new Master Cylinder. We are getting plenty of fluid out of all 4 calipers but no pressure. It seems to not be building any pressure. We also hear a whooshing/sucking noise in the front driver side but cannot pinpoint a location. We can hear this every time we pump the peddle but no obvious leaks and we are not loosing fluid.
