front to rear brake line removal help

I gather, you are saying there is not enough clearance between the axle housing and the body of the car. Put the jackstands under the body instead of the axle, and lower the axle down for more clearance. You can bend 3/16" brake line with your hands. Try and bend it around a radius, like a big socket, so that the bends aren't too tight. If they are too tight, they will restrict the flow. After bending a line, blow through it to make sure the resistance hasn't changed from tight or crimped bends.
