How do you change the steel brake line from the frame to the rubber line that goes to the axle on a 1992 dodge Dakota?

Answer 1

Sound like the main line, front to back. Trace the line up to the front and find a solid place in the line, cut it with a line cutter and get a brake flaring tool. PUT A FLARE NUT on the front section of the line and using aflarein tool flare the end of the line from the front you're going to save. Buy some steel line and run it to the back where the rubber flex hose is. Cut the old line tight to the old flare nut and get a six point socket to fit tightly over the nut. Use a line wrench to keep the flex hose from turning and loosen the old nut. Measure you new line, cut it to fit, take it off the truck and PUT NEW FLARE NUTS ON THE LINE FIRST then flare both ends & install. Bleed the brakes at the wheel cylinders and it should be fine. If you have to replace the whole line its the same proceedure except you remove the flare nut at the front end and then make a longer line. Premade lengths are also available and you use connectors to join them.
