how to blled the breaks ?

when the bleeders are open ,we think it my be the abs pump because we cant get fluid threw the rear line after the abs pump .

You may have a faulty master cylinder that is not pushing the fluid, also the ABS module needs to be bled first then start at the furthest point, hence passenger rear and ect..also check for a crimped line, some times rubber lines will deteriorate and not let fluid through..
