Bench bleed the new master by putting it in a vice, instaal either the tubes or brass plugs into the ports, push the piston of the master with a philis screwdriver, until it wont pump anymore(brass plugs used) or all air bubbles are gone(tubes), then install it on the car, have someone apply pressure to the pedal, crack open the lines just enough for fluid to seep out, then close the lines, repeat until all air is purged and only fluid comes out, tight lines and you are done! If air got into other lines, blled them as well. Use DOT3 Brake fluid ONLY! DO NOT allow master to run dry during bleeding!
