Truck Repair: breaks, break line, bleeder

Question
If the front passenger break line breaks and the master cylinder runs dry what do i need to do? The truck is a 1986 dodge 1 ton dump truck.

Answer
Not to sound rude but first replace your broken line and if the other lines have not been changed would look them over and replace them look real good where they have the brackets that hold them down that's where they like to corrode. then fill your reservoir and with two people open the bleeder at the pass. side rear wheel and pump the brakes til no more air comes out. then move on to the driver side rear and do the same. then the pass. side front. finally the driver front. make sure during the process that you keep fluid in the reservoir or you'll have to start over again.
